the straights of Magellan which renders the Passage so very difficult into the South Seas But were the whole Sublunary Globe of the same equall and uniforme superficies wee should have VVinds in most places no lesse constant then the Monsoons and as regularly govern'd by the course of the Sun It will be no hard matter to explicate the cause of the Easterly Monsoons this being the perpetuall course of the Trade-wind all the year round between the Tropiques But that they afterward revert to the VVest may possibly be occasion'd from the great Magazine of vapors lodgd about the Island of Madagascar and the Coasts thereabout which are reflected from thence by the Advent of the Sun into the Tropique of Capricorne for VVinds are both the result of rarefaction and condensation also and the rarify'd vapors not only cause a more vehement Protrusion of the Air after their dilatation but being over much compress'd in one quarter as often by the Elasticall power thereof beget a Reverse VVind in retiring to their former places So that there can scarce be a moments rest in the Universe the Atmosphere being as one continued scene of Action and Passion that I believe the Air even in the calmest days is almost every where Agitated at least by some insensible Wind. But thus farre of their distinct Species and particularly of the Monsoons In relation to their Qualities I before rejected the Hot and Dry Exhalations as too narrow and insufficient to resolve the innumerable Phaenomena of VVinds for they consist no lesse of Omnigenous Vapors Salts and Mineralls with other different species of matter and we must expect their Qualities to be Various as they have greater or lesse Allays of such Bodys Some of them are Corrosive others Suffocating and Pestilentiall they are sometimes Hot and then Cold from the same Quarter and so successively capable of all Qualities and Extremes according to the Diversity of their Constituent parts or Mediums in which they blow This might appear from many obvious Experiments Let them pass thorough a Tunnell or Pipe of a convenient length but much wider at one end then the other that it may give free admission to the Air in the cavity of which strew severall sorts of Aromatics and odorous herbs such as Thyme Roses Violets c. then let it be stuck in the wall of some house expos'd to the open fields with the larger end obverted to the VVinds and the lesser so plac'd to conveigh them into the house somewhat after the manner of the Italian Ventiducts and you shall have the whole roome perfumed with a pleasant and agreable smell but instead of these if you put in herbs or mineralls with Virulent Deleterious Qualities you shall have some complaining of their heads others seas'd with Lipothymies and inclin'd to sleepe when the stupefactive fumes enter together with the VVinds and surprise the Spirits The same we may conclude of all such whose component particles are either noxious in themselves or make their entry through unwholesome places which are stord with Antimony Mercury or other Putrid and Arsenicall vapors I made diverse tryalls of this nature instead of common Water I fill'd the Aeolipile with water distill'd from roses which generated VVinds with a very gratefull Perfume afterwards I experimented the same with severall sorts of liquids I likewise cast in Camphire and then small shavings of Juniper Wood into the Aeolipile that sent out flatulent steams according to the nature of the bodys injected which makes it evident that the Qualitys of VVinds are oftentimes deriv'd from their Constituent particles But as to the Medium through which they passe I judg'd the use of the Aeolipile by no means suitable to my design in discovering their degrees of heat or cold the Winds generated therein being actually hot before so I caus'd to be made a Tinne pipe about 4 foot long which I fitted to the nose of a pair of bellows and covering it with a mixture of snow and ice perceiv'd the. VVind which pass'd through the pipe to be very excessively cold but because our Organs are not all ways equally dispos'd nor indeed are they sufficient Criteria to be rely'd on in such nice cases I therefore made use of an Hermetically-Seal'd VVeather-glasse and blowing thereon found a very visible alteration in the liquor of the Weather-glasse which being ventilated from the same bellows wrought no such effect before the Frigorific mixture was apply'd I afterward heated the Pipe in the Fire through which the Winds should passe and there came forth an exceeding Hot blast So farre upon all accounts may the Disposition of the Medium influence the Transient Winds If wee further enquire upon what account Winds thus farre sympathize with their Mediums wee must acknowledge it to be no dreame of the Epicureans that continuall effluviums doe issue from all materiall concretes And the Winds not only bear off with them those particles which are already disengag'd from their textures but help to loosen others that ther 's scarce any Body so solid which pays them not some tribute as they passe Those which have made no farre excursions from their Fountains cannot be much adulterated in the way and so preserve their first Qualitys entire But the Travelling Winds that arrive from remote Countrys and drive before them different species of Air and mingle with other Heterogeneous exhalations in their passage they are at last quite overcome by them and so farre influenc'd by their long entercourse with the medium that they almost Universally borrow their Temperament and Propertys from thence The Winds in Italy which blow over the groves of Myrtle doe often perfume the Air for many miles and in those Countrys where the Rosemary grows wild in the fields the smell thereof has been carry'd a considerable distance from their Coasts The Levants are accounted Soultry and troublesome in Spain yet on the shoars of Murcia where they come off the Mediterranean they are agreable and pleasant The Tramontanas at Rome are often more piercing then the sharpest North Winds either in England or France because they blow from the Snowy mountains And I might instance in a remarque out of Captain James The Southerly Wind was then coldest the reason I conceive to be for that it did blow off the Main Land which was all cover'd with Snow and the N. Winds came out of the Bay which was hitherto open I conclude that VVinds have more frequently their Qualitys from the Places or Mediums through which they passe or at least from the Fountains that gave them birth then from the Quarters which are reputed Hot or Cold or otherwise qualify'd for producing such Winds As in Holland and the lower parts of Germany they have very often colder weather with the Midland VVinds though from the South then with the N. or N. E. which passe over the Sea and mingle with the tepid vapors of the Ocean The Southern Blasts to us here in England are accounted noxious
motions being excentricall to the Earth cause so unequall a distribution of heat cold that the Air must of necessity be denser in some parts then others and consequently lyable to the frequent disturbance of VVinds and the vapors according to the distinct seasons of the yeare being continually either retiring from the Poles or on their voyage thither the Sun as Prince of the Atmosphere obliges them to a motion no lesse constant then his own Insomuch that neither These or indeed any other VVinds are so fortuitous as many suppose but proceed from regular causes and are guided by the certain conduct of nature though happily the manner of it may not be fully understood by us The Norths are often exceedingly impetuous on the shoars of Florida and Virginia taring up Forrests of vast Trees by the roots and wasting the whole Country like Hurracanes They blow very hard toward the Orcades and on that side the British Coasts But they must needs be very sensible of their effects in Finmark Russia which lye more expos'd to their fury The Bishop of Upsal in two Chapters De Vehementiâ Venti Circii De Vent Sept. Violentiâ informes us of many disasters which happen by them in Norway and Island particularly that at the Port call'd Vestrabord the N. E. VVind blows with such vehemence that it dismounts the Horsemen and Souldiers driving them away before it On the Western shoars of Norwey it suffers not so much as a tree or the least shrub to grow that the Inhabitants are forc'd if you believe our Author to roast their meat with fire made of great fishes Bones And in Bothnia and that part of Norwey which they call Vichia the Northern Whirlewinds are so terrible that they carry away the roofs of their houses and of the Churches which are cover'd with lead blowing away great beams and rafters removing Wind-mills stones and even Castles and Villages from one place to another If this be an Author suspected the Annals of our own Country will furnish us with relations of the same nature which would require as large a share of credulity to believe them if the rage of these Tempestuous Winds was not sufficiently understood in most parts of Europe though happily in remoter Climates which are less acquainted with the great Disturbers of the Northern World they might seem fabulous Some of which are solemny recorded in our Historys that even exceed the Hurracanes of the West Indies Yet I have heard that those Winds which we count very great stormes here in England would be thought no wonder in Scotland where they are accustomed to these violent Blasts and for this reason build their houses universally with stone exceeding thick low and with narrow windows But not to be prolix in their History we might offer at the cause whence this strang vehemence and impetuosity of the N. VVinds does proceed Shall we say from the great quantity of exhalations laid up in the Treasuries of the North or because they find the resistence lesse toward the South where the Atmosphere is rarified by the heat of the Sun so that they glide without opposition through the yeilding Air especially in the day time wherefore the aforesaid Northerly Winds are observ'd to blow harder by day then night They are more Sonorous then other Winds because they rage with greater violence and so make a stronger collision of the Air. I have thus farre considerd their nature in the remoter parts of Europe where they are nearest their Source But after they have made a long Progresse Southwards and are heated in their approaches towards the Sun we find them in Africk to be farre different from what they were in Norwey or Island and their qualityes no lesse various then the Temperature of the Heavens So likewise in America and as Acosta observs more particularly of some Countrys in Peru the Northerly Wind is counted unwholesome and the Southerly extremely cherishing to men and beasts The first is not penetrating nor disperses clouds as among us but causes rain and the South Wind is just qualify'd in those climes as the North is in our country's that lye nearer the Arctic Pole Nay not only comparatively to different situations and places but the judgment to be made concerning the Qualitys of Winds from the Quarters whence they blow is very various and fallible in relation to one and the same Latitude Many of the hardest frosts which have happend in England began with a Southerly wind and then commonly are the more lasting and violent which nevertheless is generally much hotter then any other which arrives at the British coasts I took notice no longer since then the 11 of January last that in the morning we had much rain the wind being N. and N. E. which ceasing about noon there followed first a showre of haile and then a considerable fall of snow the wind still continuing at N. and N. E. which was the most part of it dissolv'd by 3 or 4 in the afternoon then the VVind vering to full South it froze exceedingly hard for the time So little certainty is there in observations of this nature that we had Rain with a Northerly and Frost with a Southerly VVind in the same day And not only thus but it appear'd by the Weather-glasse to which I had recourse upon this occasion that there was a very suddain mutation in the Air from heat to cold when the Wind came about to the South more then in the morning while it continued at N. and N. E. VVee must expect these so different Qualifications of VVinds to happen even in the same Climate since not only the Variety of their Component Particles and the Fountains which gave them birth but either the Cutting down Forrests Draining of Fenns Changing the Currents of great rivers Their Vicinity or Distance from the Course of the Sun whether they blow off from Land or Sea or Snowy Mountains and a thousand extraneous accidents are sufficient to alter the Properties of Winds Neither are the laws of their Motions reducible to such certain rules as Aristotle pretends That two Opposites alwaies blow at Contrary Seasons of the year As the N. W. about the Vernall and the S. W. at the Autumnall Aequinox and it would likewise be examin'd whether the same Contrariety happen constantly between the Solstitiall Winds Others have observ'd that wee commonly feel a a S. Wind at midnight an Easterly at the Rising and a Westerly after the Setting of the Sun and last of all a Northerly about Noon when the Solar rays are most powerfull to resolve the grosser mists and clouds in the North. For VVinds being for the generality Nothing but Dilated Vapours or Air they almost wholly depend on the Presence of the Sun at least are generated from the heat left behind him in the Earth and Waters VVhereupon De-Cartes ingeniously remarks that wee should have no such Variety in the Qualities and Production of Winds if the whole

THe Origines of Winds are no lesse Various then their Motions we ought not to determine positively concerning those Appearances in nature which may be rationally explicated severall ways Though we consult the Placits of the learned Ancients consider also what we owe to the improvements of latter times yet I question whether any Theory was ever yet started on this Argument which will adequately resolve the whole Phaenomenon of VVinds and we must never expect to confine their Originall to any one determinate Cause Most of the Graecian Philosophers agreed in the same Definition of Wind till the Prince of the Peripatetiques was not only ambitious to establish a New Hypothesis of his own but likewise undertook the confutation of his Master Plato the rest of his Predecessors The Philosophicall Monarch thought he could never raign securely in the minds of men unlesse like the Family of the Ottomans he destroy'd all his Bretheren first I have no intention to disparage the Authority of the Ancients but I cannot be so injurious to the many noble productions of our present Age to think that all Science is only to be sought for in the Urns of the Dead we have a more intimate converse with Nature then heretofore which displays her beautifull Bosome and every day affords new Discoveries of usefull knowledge and further conducing to the Benefit of Human life If we consider the successe that Philosophy has met with in the VVorld we shall find that those Opinions which obtain'd most in one Age had their Fatall Periods were as much exploded decry'd in the next it 's as impossible that any one Hypothesis should be calculated to the Gusto of all persons when the sentiments of men are different as their complexions I have therefore taken a larger compasse then the Generallity of writers and deriv'd the Origines of Winds from severall Causes which I rather endeavour to prove from Accounts of our Sea-Voyages and relations of Matters of Fact then to refine on them by any nice speculations of my own For this Philosophy is not to be had in Colleges or Books but must be fetch 't frō both Indies we must traverse the wide Seas be tost to as many points of the Compasse as Columbus or Drake we must climb into the Regions of the Air descend into the Caverns of the Earth to detect the innumerable Causes Qualities of VVinds They are diffus'd like the Universall mind and it requires a kind of ubiquity to understand them How small a portion is it of the vast system of the World that we inhabit and how much lesse of it that we comprehend How Extravagant are the Phaenomena of the large American tracts their Tydes VVinds and other Aeriall impressions how different and irreconcileable to Ours How many noble discoverys have been made in these Countries which the Athenian Sages could never think of in their narrow Porches Gardens They might spin fine webs out of their own bowels but for want of a closer inspection into Nature their Texture Materials are slight And we must acknowledge that even the Stagirite himself has left us no very perfect Theory of VVinds though this Province of late years has been more succesfully undertaken by the Lord Verulam Galileo De Cartes and other illustrious Moderns Aristotle constitutes two species of Exhalations the one vapid or moist the other 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 Fumid or Terrene and as the first is employ'd in Rain Hail or Snow c.

W. throughout all India from noon till 12 at night and coming out of the Sea towards the Land are therefore call'd Viracoins or Sea Winds They often stay late and blow but slowly Nearer the Coasts of China you have the Terreinhos out of the West and N. W. S. E. and E. N. E. Being in the North they change to the South and then ensues a calme till the Terreinhos come in The Brises in the Straights begin about 9 or 10 in the Morning blowing freshest at noon and so gradually declining till 4 or 5 at last cease in a Calme which lasts till 10 11 or 12 at night VVhen begins the Land Brise till 5 or 6 and then Calme till the Sea Brise comes in This account I receiv'd from a Sea Captain well vers'd in all parts of the Levant having serv'd under the Venetians severall years in those Seas At the river of Constantinople the VVinds commonly blow thorough but in exceeding fair VVeather you shall have both the Land and Sea Brises as in the Straights If either the Easterly or VVesterly VVinds blow fresh they hinder both the Land and Sea Brises in the Mediterranean of which wee must note They are always the more languid and weaker the later they come in In very hot days and when no other VVinds are stirring you may sometimes observe this alternation between the Land and Sea Brises on the Coasts of England but scarce with any certainty beyond the Latitude of Portugal Brises of all sorts are more constant in Summer then Winter and between the Tropiques then in the Temperate Zones The Etesians or Anniversary VVinds are those which blow constantly at certain seasons of the yeare The most remarkable species begin in Summer about the rise of the Dog starre and last 40 days being preceded by their Prodromi or Fore-runners 8 or 10 days The account of Pliny is not much different from Aristotle as he computes their Etesians in the 2 d book of his Naturall History Not only the Stagirite and Theophrastus but of late De Cartes and many other Moderns derive their Origine from the colliquated snows and ice in the Northerly regions For the long continuance of the Sun neer 6 months together above their Horizon at last overcomes the obstinacy of the cold and dissolves the snows which being attenuated into VVinds make long marches towards the South where they find the Air more yielding and pure then the Foggs and grosse vapors of the North. They were call'd the Sleepy VVinds Venti Delicati Somniculares by reason they intermit in the night time and rise again with the Sun happily because the vapors were then only sufficiently dilated by the celestiall beams though in the night time they subside and hover neare the Earth being too refrigerate and dense to constitute VVinds till they are again quicken'd put in motion by the approaches of the Sun I am willing to acquiesce in the aforesaid cause and I believe wee in England or France might owe our Etesians to Groenland and other parts of the Frozen Zones because wee have no constant visible Fountains of any such VVinds in our own dominions but if the Etesians of Greece according to the sentiments of Aristotle doe allways depend on the resolution of snows in the North they would certainly take Russia Poland or Germany in the way which lye neerer the Artick Pole before they arrive at Greece and yet on the other side of the Taurican hills they are said to have Southerly VVinds about the time of the Graecian Etesians VVee may better make judgement of these Winds that being most Peculiar to this Country they were no Forreigners in their Originall but sprung from particular Fountains within it selfe such as the hills of Macedon and Thrace that have perennial Snows of their own and these being master'd by the scorching heats of Summer may give birth to their Etesian Winds which has this advantage over the other opinion that it clears the difficulty why they are silent in the night and blow with fresher Gusts at Midday when the Sun mounts highest in the Northern Hemisphere I shall only adde not to mention severall others of the modern Naturallists that even * Cabeus himselfe who was a person sufficiently Zealous in asserting the Peripatetique Hypothesis dissents from the opinion of Aristotle will scarce allow the Etesians of Greece a remoter Origine then the neighboring Alps. I shall not insist upon the mistake for which some of his own interpreters have severely enough reflected upon Aristotle That he should first deduce the Origine of these VVinds from the Frozen Zones and afterward assign the reason why they blow stronger in the Day time because the liquefaction of the Snows is interrupted by the Nocturnall Cold when it 's Notorious that in those Countrys the Sun for many Months together is never depres'd below their Horizon Towards the Adriatique and many parts of Asia they have Set Winds which arrive from the N. and N. E. Yet all these which were reputed the Venti Stati blow not from the Northerly Points for in Gascony about the same time with the Etesians of Greece they have rather Southerly Winds which Scaliger who was best able to judge of his own Country observes to be unwholesome and Pestilentiall At Madrid for the most part of the Summer they have a Brise from the Pyreneans or the Adjacent Guadarama which extremely allays the excesse of heat You shall have different sorts of Winds from the same Snowy mountain blowing to severall quarters according to the situation of the Countrys As was observ'd in those Countrys by the foremention'd Cabeus Saepe nobis Boreas Borealibus Auster Spirat It being not unusuall for them in Lombardy to feel a Northerly and at Tirol which is situate on the contrary side of the Alps a Southerly Wind at the same time In Italy they can never fail of Etesians from their own Appennines and so happily on the shoare of Guzarat and the Indian Ocean from mount Caucasus And where ever great Chains or ridges of Hills run along as the Caucasean or Appennine this very often renders an account of most Etesians there about Yet I question whether many Authors may not ascribe too much to this one cause for in some places they have Anniversary Winds that can never possibly have their rise from the Resolution of Snows And I believe it would prove extremely difficult to lay down any tolerable Hypothesis of the Monsoons on the Coasts of Afric and India from the best discoverys wee have yet been able to make of those Parts There are other Stated or Anniversary Winds which they call'd 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 Avicular and White-South Winds either because they were so friendly to the procreation of birds or rather that they return'd with Nightingales or Swallows in the spring beginning to blow after the Summer Solstice by the computation of Aristotle 70 days about the beginning
and Pestilentiall but to certain African Provinces healthfull and Pleasant The Northerly are coldest in our European World and the Southerly on the other side of the Aequinoctiall For the Arctick and Antarctick VVinds must needs be of the same nature blowing from either of the Poles where the cold is equally predominant So that the Qualitys of many VVinds seeme not so much to respect the Points of the compasse as the Course of the Sun The Eastern Winds according to Aristotle are hot and dry nor is their Siccity only remarkable in Greece Palestine Asia the Lesse and most parts of Africk where they make long marches over the parcht and barren sands but likewise in the more temperate climes of Holland and France by reason they passe through Poland Germany other vast tracts of Land and lastly arriving at our Isle they can suffer no considerable alteration in their qualitys by so small a passage over the Narrow Seas They are no very welcome guests to us in England being ominous to our Gardens Fields by blasting the corn and fruits I have known strange destruction done in one Night when they come late in the spring Sometimes they not only blite the leaves and blossoms but kill the Trees with their poysonous breath They bring after them swarms of Caterpillers and other devouring insects or those dry and tabid mists which corrupt the lungs and cause Epilepsys Consumptions c. whether by driving before them the putrid Air from Holland or however they contract that malignity in their natures Nevertheless wee can make no Generall conclusions of their propertys from hence which are chang'd by innumerable acidents For though in these Countrys of Great Britain they are inauspicious both to animals and plants yet in the West Indies the Eastern Brise is refreshing and healthfull above all other VVinds. In Arabia and those Asiatique regions they are exceedingly dry by travelling for many thousand leagues over the sandy desarts yet Blondus observes them to be rather humid in Italy and to occasion a relenting in the Air where they blow immediately from the Adriatique Seas In relation to their degrees of heat though Aristotle declares they are much hotter then the Westerly wee find by experience that with us in England the Easterly are at certain Seasons of the yeare exceeding cold and very often the most freesing winds especially if they hang somewhat towards the North. I need assign no other cause for the frigidity of the Easterly Winds then that they have their first rise from the Continent where the Midland Air is much colder then the Maritime The South Winds are generally reputed Hot and Moist on this side the Line being heated in their entry through the Torrid Zone or because they consist not of melted Snows as the Northern but of the Tepid and Sulphury steams from Africk and other Sunburn'd climes They passe over no Seas of any large extent just crossing the Mediterranean and British yet they moisten and relax the Air and cause wet weather by dissolving the Clouds into rain which are rather dissipated and blown over by the impetuous Norths Yet I think it very irrationall to conclude that all the Southerly should have their rise from the Torrid or the Northerly VVinds from the Frigid Zones Since it is not unknown to the Curious that in part of Italy and Provence they have very often Northerly VVinds rising as is suppos'd from some places about the Alps whereof they are not at all sensible in other Countrys of France through which they must of necessity passe if they came so farre North. In like manner at Marseilles and in the Mediterranean they have oftentimes Southerly VVinds when they blow from contrary points on the African Continent which lyes more to the South I believe very few of the South Winds here in England ever took a longer flight then from the Mediterranean Sea or the lower parts of France and it can scarce be suppos'd that the same Numericall Exhalations could ever travell from between the Tropiques and not be spent in the way long er'e they arrive at the British Coasts yet happily by protruding the Ambient Air and that successively the Contiguous to it the motion may at length be Propagated many hundreds of Miles beyond the reach of those vapors which caus'd the first Agitation So that it is not impossible but that a VVind which began neer the Aequinoctiall may by this means be continued even to the Poles of the VVorld However I shall make no longer digressions concerning their Extent but proceed to the Qualitys which are vulgarly ascrib'd to the Southerly VVinds. They are laxative stupefactive and pestilentiall They cause Epilepsies and pains in the head and were therefore styld 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 by the Grecians They render men Shaagrin and melancholy and in some of the Azores Islands the children are said to sit dejected and leave their playing when they blow For first they open the pores of our bodys by their heat and then insinuate the malignant influences and the parts being pointed and volatile have not only an easy ingression into our blood but thaw and unloose the textures of ice and snow Nay it 's most certain that iron it selfe takes the file much better when the South Wind blows then at other times They many times cause a farre rougher Sea then the most Tempestuous Winds from the North Happily because they blow more obliquely and rake the Surface of the Water when as the Northerly oftentimes descend as from a precipice downwards which immediately deads and weakens their force They magnify visible objects As our Seamen observe their ships to appeare bigger at a distance either in misty weather or when the South Wind blows For the humid and nebulous vapors of which they consist distort the visual beams and by refracting them to the Perpendicular cause more rays of light to enter into the eye which makes the object seeme larger then otherwise would arrive at it in strait lines Many who are naturally inclin'd to Stammering in their speech do find their infirmity evidently worse when the Wind is toward the South Probably because the moisture of the Air causeth a greater relaxation of the Nervs and thereby a tremulous and unstable motion of the muscles at that time Which perhaps hath more power upon the Vocall muscles then others because they lye in the Road and are more expos'd to the invasions of whatever is breath'd in at the mouth or nostrills then others are Whence also wee find the tongue more apt to falter though somewhat in a different manner whensoever it is overmuch bedew'd with strong and vaporous liquors Smells are said to be most Fragrant in these Winds when the Air is humid and lax to convey the odoriferous particles They anticipate the Spring and cause the trees to blossome and bud forth before their time and by this means exhaust their spirits and nutritive juyce They damp linnen and paper though never
Terraqueous Globe were of one uniforme superficies as wee may perceive that in wide Seas their motions are farr less irregular then by Land since the great diversity of Climates Mountains and Lakes varies them exceedingly I have thus farr discours'd of the 4 Principall the Collaterall or Intermediate VVinds if any right judgment could be made of their natures from the Quarters whence they blow might be suppos'd Hot Dry Moist c. as they are farther remov'd or hang nearer towards the Cardinal Point But we are like to expect little satisfaction from the generality of writers concerning the temperature of VVinds For who can with patience hear the impertinence of those Notionall men that enquire no further but declare That the South Wind is allways Hot and Moist the North Cold and Dry the West c. which obliges us in the following discourses to offer at some more accurate account of their Qualitys and the most Universall causes from whence they proceed First VVinds are Moist either because their Constituent parts are made up of Vapid and Aqueous corpuscles such as rain dews watry Clouds or by reason they make long Voyages by Sea or over great Lakes Morish Countrys Fenns and so are tainted with the Qualitys of the Medium through which they passe Those which proceed from Melted Snows have some small allay of the Terrene but approach neerer the Moist The Siccity of VVinds is from their Saline and Terrestriall parts or that arriving from those Parc'ht and Torrid regions neer the Line they are exsiccated as they travell by the Ways of the Sun I shall not dispute whether this has been cautiously enough minded by most writers How many nice circumstances are to be consider'd in judging the Qualitys of VVinds and how difficult it is to make a just Estimate of their severall degrees of Heat and Cold. For there must not only be especiall regard had to the Temperament of our Senses but to the Climes in which they blow and seasons of the year Since those which would seem hot at Christmas comparatively to the winter Cold should the same happen in July when wee had been long accustom'd to a different temperature of our Organs and the Ambient Air would undoubtedly appeare exceedingly Cold. Then wee denominate VVinds either Gelid or Hot in respect of those that usually blow in such Climats as the Southern Blasts with us here in England though they are Colder then the Ambient Air may be reputed Hot comparatively to the N. or N. E. which are much more refrigerative in these parts of the VVorld Thus wee ought not rashly to make judgment of their Qualitys but first consider what Symptoms of Heat they betray in relation to Weather-glasses or the Winds that commonly blow in such Countrys as likewise what mutations happen by them in the Temperature of the Air And afterwards compare all these Circumstances with the present disposition of our Organs least wee determine concerning the positive Qualitys of VVinds from only the Prejudices and Hallucinations of Sense There are severall Causes Productive of Heat As their passage through Hot Regions Or because they consist of the ignite and suffocating Air which infests the Burning Zone where the whole Masse is corrupted with such intolerable heats that the Winds which are either generated therein or only pervade the Torrid regions must needs for some time retain their temperament and Qualitys till at length they loose them in long voyages and the calorifique particles languish and dwindle away by degrees being oppres'd with multitudes of Heterogeneous exhalations in their course Then I think it not improbable but that the Solar rays or whatever parcells beside of the Subtil and Aetheriall matter may by mingling with them actually advance the heat of VVinds. And Lastly The ignite Damps such as wee sometimes discover in Colepits and Mines and all other of the Minerall and Metalline Kingdomes that finding no Vent cause Earthquakes in the Bowells thereof if they escape through the Pores of the Earth occasion Presters and Hot VVinds And those fiery eruptions which in many places of Calabria and Sicily are continually breathing out from the Subterraneall Regions must needs diffuse the seminals of heat through the whole body of the Air and VVinds especially such as come reaking from under Burning Mountains or at least are the results of those Calorifique mixtures by which some Mineralls and salts fermenting together in the Cavitys of the Earth emit Hot fumes Like severall Chymicall preparations such as Oyl of Tartar and spirit of Vitriol which cause a strange Ebullition and Heat by their commistion only And if wee suppose any thing Analogous to these under ground where Nature in her own Elaboratory often exceeds the greatest Sagacity of Art why may not the Tepid Steams and Vapors that ascend from thence be able to produce so considerable a degree of Heat in the Air that might occasion Scorching Winds And happily the Rancounters of Certain Mineralls with each other in those Passages where the VVaters flow may likewise by their mutuall ferments be the most probable cause of many Hot Baths Springs Neverthelesse Fromundus some other Naturalists of late in the Number of which wee may reckon our Countryman Mr. Hobs affirme that all VVinds whatever doe actually refrigerate and oftentimes so intensly that they prove the fittest instruments for the Congelation of Liquids And I must confesse it seldome falls under our observation that in any parts of Europe the VVinds are comparatively hotter then our Sensories or the Ambient Air yet in many Provinces of Afric Arabia but most of all near the Persian Gulf where they come just off from the Burning Sands they are intolerably hot and suffocating as appears from the Relations of the Portugalls first Voyages to the East Indies where they felt Gales of the E. and N. E. Wind so Hot that the Air seem'd to be inflam'd and scorching like fire So likewise Gasparo Balbi in his Travells speaks of four persons that weary'd in their Journy sat down near the Banks of Euphrates to refresh themselves a while and were all stifled by one of these Hot Winds And wee have a more surprising Narrative from Marcus Polo that when the King of Chermain sent an Army of 16 Hundred horse and 5 thousand foot against the Lord of Ormus for not paying his Tribute they all perisht by these Suffocating Blasts But if wee distrust the integrity of these writers Olearius in his Voyage to Persia describes the intemperature of the Air in those Countrys to be such that with the North or East Wind they felt a Cold which depriv'd them of their Limbs and on the Contrary the S. Winds were ready to choak them with the extremity of heat But Della Valle a Nobleman of Rome whose Curiosity led him through most of the Eastern Kingdomes reports that towards Arabia there was a VVind so scorching and Dry that it left behind it like marks of Fire wherever it came
