produce these Fetors by Separation of a Volatile Oyl and Salt from the Acids and Earthy Parts of the Plants So Spirit of Soot has an Oyly Salt and the Fetid Oyly Salt is easily separated from Vrine and Blood after Putrefaction Many Acrid Plants are Fetid so Sophia Chirurgorum and the Pouches of Aron are abominable Cotula Faetida Nettles Garlick and Onyons have an Acrid Taste and are very Fetid So is Galbanum Assa Faetida and Sagapenum Divers Bitters are Fetid as stinking Horehound and all Elder-Smells as Scrophularia are Bitter-Fetid So the stinking Gums are Bitter as well as Acrid and Fetid The Mucilaginous are also Fetid as in Atriplex olida That there is but a Difference in degree betwixt Aromatick and Fetid Plants appears by many Instances as Galeopsis smells Fetid at first handling afterwards Aromatick The Flowers of Valerian are very strong and offensive at first getting after a little drying they are Aromatick So in the Preparations of Musk and Civet if in a great quantity or while fresh they stink afterwards in a small quantity they are more grateful So the Leaves of Coriander stink but the Seed is Aromatick Elder-Leaves are Fetid yet the Flowers are very Fragrant so are the Flowers of Saponaria though the Leaves resemble Elder The Blossoms of most Trees are Fragrant though the Leaves smell Crude From the afore-mention'd Instances Fetids are 1. Bitter 2. Acrid 3. Mucilaginous which are generally Narcoticks From the afore-mention'd it may be inferr'd that Fetids inwardly are of a very hot Nature discussing Tumors outwardly and opening the Pores Inwardly Fetids by their Volatile Parts do pierce the Channels of the Nerves mend the Crudity of their Nervous Juyce and by their Faetor they excite a different Motion from that in Hysterick Fits and in Convulsions and do remove the Cause of that tumultuous Motion in the Spirits by correcting Acidities and Stagnation in the Succus Nervosus which is disposed to them as all other Glandulous Liquors be Narcoticks have all of them an heavy offensive Smell like Poppies or Solanum or have a sweet heady Smell like Roots of Bears-Ears Milky-Narcoticks taste Mucilaginous Bitter and Acrid as Poppies and Lettice The Milky Juyce is an Argument of an Oyl and the Acrid of a Volatile Salt adjoyned Opium is a Bitter-Acrid has a Resin and Gum inflammable Though it 's easily extracted by the Spirit of Wine yet the Bitterness and Acrid in which its Vertue is founded is most corrected by Spirit of Vinegar Juyce of Lemons Juyce of Quinces or any other Acid as well as by drying it and evaporating some Part of the Narcotick Fume The Second Class may be of Bitterish Sub-acrid Mucilaginous Narcoticks as Solanum Lethale Bacciferum Stramonium Cynoglossum Besides the Pungency Solanum Lignosum has a Bitterness The Roots of Cynogloss boyl'd smell like Spirit of Harts-Horn Fresh Tabaco smells Narcotick about the Flowers and is Bitter Mucilaginous and Acrid It much resembles Henbane by its Figure Oyl and Clamminess to the Touch but by its Bitterness and Pungency Solanum Lignosum The Third Class of Opiates is Sweetish Acrid and Fetid differing from Poppy smell as Cicutaria Napellus The Roots of Henbane are very sweet These produce Giddiness with a stupor and their best Antidote are Acids as Vinegar The Fourth Class has a Bitterish Acrid Taste as Cowslips and these have also a Fragrancy very heady being of a low degree amongst Opiates The Roots of Cowslips are very Acrid and Bitterish By the afore-mentioned Instances it appears that Opiates have very hot Effluviums which offend the Smell By the same Opiates inwardly produce Sweat in so small a quantity as one or two grains and are very Fetid by their Oyly Acrid Salt which runs through all the Classes of Opiates The Bitterness and Sweetness in some Opiates no way conduce to encrease their Soporifick quality but are different in many Opiates Narcoticks taken inwardly immediately affect the Nerves in the Stomach and produce an heaviness there which I have been sensible of in tasting the Solanum and Poppies and they cannot pass a Digestion and Separation nor by a circulation arrive at the Brain so soon as their effects are produced therein Therefore Narcotick Fumes must pass through the Pores of the Nerves and begin to fix the Spirits in the Membranes and Nerves of the Stomach by which a stupor is communicated to the rest Something of the Opiates passes a Digestion and afterwards a Circulation through the Blood where it makes no alteration by its Narcotick quality but being Bitter and Acrid it produces a Diaphoresis as others of that Taste do In the Nerves these Narcotick Fumes weaken the brisk expansion of the Spirits which causes waking and their too great Agitation which causes pain and likewise stops their Tumultuous motion in Convulsions and the violent motion of the Heart and Pulse as well as any Flux of Humors whatsoever by abating the violent contractions of the irritated Fibres Humors that are Acid are corrected by the Acrid Taste and Bitterness but Choler can no other ways be helped but by abating the Acid combined with it and making it corrosive as well as by stopping the motion and evacuation of it From the Symptoms allayed by Narcoticks I argue That they work not as Oyls and Volatile Salts though they have them for they rather produce an expansion agitation and tumult in the Spirits And I also conjecture that the Narcotick Faculty is best deducible from such a combination of the Volatile Oyl and Salt with a Mucilage as to gain thereby a particular Figure Motion or Texture by reason of which it weakens the motion of the Spirits and in too great a quantity destroys their fluidity Burnt Alum mixt with Gun-Powder destroys its Elastick force and weakens the burst of a Gun. Water loses its fluidity by the small Particles of Cold And Mercury is made Solid by the Fumes of Lead Nothing can be more easily fixt by divers additions of other things though in it self it has a greater Agitation of parts than other fluids which being stopt in their internal motion become Solids and if Opiates do weaken or deprive the Nervous Juyce of its Internal Agitation from thence all their Phaenomena may be explain'd All Narcoticks have offensive Smells by which we are taught by Nature to avoid them and this Antipathy can proceed from nothing but the disagreeable Texture and Motion of the Narcotick Fumes to our Spirits Opiates cause not Sleep unless in great quantity in Consumptive Bodies for in them a little quantity troubles the Head and disturbs the Spirits with Giddiness because their Spirits are very hot and fiery and their motion for want of a serose Vehicle very violent but it seems not probable as some conjecture that one grain of Opium should force so much Serum to flow to the glandules of the Brain as to fill them and produce Sleep by too much diluting the Spirits Whereas we frequently drink a full Gallon
of Water or other Liquors which supply a greater quantity of Serum without causing Sleep Opiates by their sharp Acrid Salt stimulate as Venereals and by their Bitter Sliminess and Acrimony they purge A slimy Mucilage attends Opiates which outwardly has a good effect to temper Heat in Inflammations whilst the Effluviums that are Narcotick abate the Agitation of Spirits By their Mucilage Opiates may repel and also inwardly given by the same they allay sharpness of Coughs and corrosive Salts whilst their Narcotick Fumes fix the motion of Humors by robbing the Spirits of their Activity by their Bitter-Acrid they discuss and by their Mucilages mollifie Tumors as inwardly their Bitter-Acrid corrects the Acid the Mucilage tempers the Choler and for this end the Poppy-Syrups and Waters are the best having more Mucilage than Acrid or Bitter But Opium more Bitter and Acrid than Mucilage wherefore it is more convenient in Acid Humors CHAP. IX Of Volatile Salts and the Tastes and Vertues depending on them IN many Plants there is a Volatile Salt discernable by the Acrid Pungency produced on the Tongue as in Aron-Roots That this Pungency is a Volatile Salt though it has no Saltish Taste appears by the following Experiment I distilled some Mustard-seed in a Retort which afforded both Oyl and Spirit which being rectified turned Syrup of Violets green though this Salt in its natural state will not so readily turn Syrup of Violets as Animal Salts do The Infusion of Aron-Roots in Water did a little green the Syrup of Violets after some time Spirit of Scurvy-Grass or Aqua Raphani composita would not turn Syrup of Violets nor Horse-Radish-Roots infused in Water tho' the leaves bottled with Water turned the Syrup after some time Juyce of Aron-Roots would not turn it the Leek-Roots sliced into Water mixt with Syrup of Violets turned it after a long time The mixture of other Principles with the Salt hinder its greenning of the Syrup of Violets So a Decoction of Harts-Horn for the same reason will not do what the Spirit does in turning the Colour It 's well known that Vinegar and other Acids as Lemmon Citron Sorrel do best correct the Pungent Acrimony of the Vegetable Salts and therefore Vinegar is used in Sallets Oyl is used for the securing of the Stomach from their corrosive Acrimony Yet the Acrid Salt of Vegetables will not ferment with Acids as the Animal Salts do Juyce of Aron-Roots and Spirit of Scurvy-Grass will not ferment with Oyl of Vitriol These different Classes I have observed in the Volatile Salts of Plants The Watry-Acrid having a pungent Smell like Mustard or Scurvy-Grass and the Cresses These have a tolerable Pungency and but a little Oyl with their pungent Salt. The Vertue of these Cress-tasted Plants is first from their Salts which excite Appetite and volatilize the Acid Ferment in the Stomach and therefore are Stomachicks In the Blood they amend the coagulating Acids open Obstructions in the Spleen and Brain and all the Glandules and therefore are Antiscorbutick Splenetick Diuretick and Sudorifick outwardly they discuss and have the Virtues of Volatile Salts in Pains and Scald-Heads and Scorbutick Spots By the Watry crude Parts adjoyned they temper their own Acrimony and make it more agreeable to hot Bloods as in Brooklime I distilled Colewort-Roots which tasted like Horse-Radish and had an Acid mixt with Pungency which would not turn Syrup of Violets this distillation was in Sand in a glass Retort There are many degrees of Pungency in this Class so that choice may be made for particular Constitutions There is a Bitterness in many of this Class which helps the Operation of the Acrid if the Acrid prevails they belong to this Class if the Bitter they are referrible to the Bitters with Acrimony The second Class of Volatile Salts is in rank Tastes and smells like Garlick and Onyons whose Smells are rank Fetid and their Tastes very pungent Hot. From Horse-Radish Leaves bottled up with Water two Months and from their smelling like Garlick as well as from their pungent Taste and quick flying up the Nose and Eyes like Sal-Ammoniack I conclude that the Cepaceous kind would very properly constitute a second degree of Volatile Salts and a much stronger than the former They correct Acids and Phlegm in the Stomach and excite Appetite by their Pungency they attenuate the Phlegm in the Lungs and open Obstructions there by their Volatile Salt and therefore are good Pectorals and Stomachicks They alter the Blood as Volatile Salts and are good against Infection and the Scurvy and as Diureticks by their Salts they are good for the Dropsie outwardly they discuss more than the former Class and their Mucilaginous Roots are emollient and ripen Apostumes and by their Salt they draw forcibly and discuss and attenuate Thlaspi tastes like Horse-Radish and smells like Garlick The third and highest degree of Vegetable Acrid-Salt is in the Exulcerators Vesicatories or Corrosive Tastes These have an Acrimony that destroys the Organ of Tasting as among Animals a fierce Volatile Salt is in Cantharides which is Vesicatory And strong Spirit of Sal-Ammoniack blisters the Tongue So in the first Class of Exulcerators there is a very Acrid Taste and quick pungent Scent depending on the Salt only the Plant being Watry having no strong Oyly Smell and these may be called Watry Exulcerators as the Ranunculus Anemone Aron Dragons Ranunculus flammeus Vesicatories pierce the Pores and by their pungent Acrimony irritate the Glandules in the Cutis to send forth their Serum and separate the Cuticula into a Blister The Corrosives have a higher degree of Acrimony they pierce the Cuticula and Cutis with Pain they alter and tear their Pores drive out their Serum and thereby induce an Vlcer and corrosion of the Cutis Note That the first Class is Vesicatory or Corrosive Watry The second Class is where the Volatile Salt is mixt with a hot fiery Oyl as in Euphorbium Ivy-Gum and these Plants have a strong Smell with an Acrid Taste The Milky or Resinous Exulcerators have an Oyl more fixt joyned to an Acid-Acrid Salt as Tithymalus and Esula and these smell Acid rather than of any hot Scent Mezereon and Laureola have a faint Lily-Smell in these the Oyl is not much conducing to any Corrosiveness But that depends on the Volatile Salt alone made more Volatile by addition of some Oyl The third Class of Corrosives is in the Acrid-Acid as Rosa Solis which is accounted Vesicatory but very mild the Acid being contrary to Volatility Acids mixt with Minerals as in Crystals of Silver and Aqua Regia become Corrosive and divers other Minerals which are not in themselves very sharp by their mixture become Corrosive as appears by Sublimate Lime has a mixed Salt. This sort of Corrosiveness happens in the fixt Salt of some Plants as in the Salt of Ash-Tree Acids become Corrosive in the Fire by their separation from Earthy Parts as in Salt-Peter Spirit Oyl of Vitriol Aqua Fortis
is very nauseously Sweet and Manna Gummy It is the Gum of a Tree and by the very sweet Gummosity it is Purging It also contains a very Acid Spirit by which it is injurious to the Hypochondriacal and good for the Cholerick Acids are given with it to abate the luscious Sweetness Honey By the Sweetness it is Diuretick Mel. and Pectoral It is partly Vegetable and has an Animal Digestion In Distillation it yields an Acid Spirit by which it is offensive to the Hypochondriacal Honey contains also an Oyly Spirit by which it is Vinous in Liquors after Fermentation and by the Acid outwardly cleanses Vlcers It seems to partake of the Nature both of Watry and Turpentine Gums Sugar is a Salt very Sweet and Oleous Saccharum and therefore inflammable It melts without Water at the Fire mixes with Oyl and by Fermentation yields a burning Brandy Spirit Therefore the use of it is very inflaming to the Blood by the Oyly Part and by the Acid corrosive which it yields in a strong Fire It is like the Acid of Tartar as all Essential Salts be which are more or less mixt with the Oyl of the Vegetable From this great Quantity of Oyl mixt with the Acid the Sweetness arises And because Sugar is dissolvible in Water as the Gums be and may easily be turn'd into a Gummy Consistence as happens in boyling of Sugar with Acids I think it fit to place it here amongst Gums whose Taste it resembles more than the Tartarous Salt of Vegetables CHAP. II. Of Fetid Gums FEtid Gums were originally Milky Liquors They are strongly Bitter or Bitter-Acrid and have a Mucilage whereby they soften and a Volatile Oyly Salt whereby they discuss By an Acid the Mucilage is coagulated into a Watry Gum and the Oyly Volatile Salt which gives the Foetor is coagulated into something of a Resin whence the Gum is dissolvible into a Milky Liquor by Water and the Oyly Salt is best extracted by Spirit of Wine Tartariz'd These Gums are frequently dissolv'd in Wine or Vinegar and put into discussing Emollient Plasters but the Vinegar abates their Acrimony Opopanax is from the Root of Panax Opopanax and tastes Gummy very Acrid and Bitter and smells like Garlick It is Emollient and discussive outwardly inwardly it is Carminative loosening the Belly Pectoral and Diuretick Sagapenum smells Rank and tastes Biting Sagapenum like Garlick and is of the Nature of Opopanax Bdellium is Biting very Bitter and Bdellium Gummy and of the same Vertue with the former Opium is very Bitter Acrid and Gummose Opium and of a Poppy-Smell It is Inflammable and Resinous and is the greatest Opiate It is Diuretick Venereal Diaphoretick and sometimes it vomits and purges Euphorbium is very Burning and Exulcerating Euphorbium in Taste and of a Fetid piercing Smell not to be us'd inwardly but externally in drawing Plasters and for Carious Bones The Acrimony may be corrected by Acids It is said to be a Tithymal and all Tithymals have the same Vertue Euphorbium is the Gum of a Milky Plant purging violently and sneezing strongly Gum-Ivy is of an offensive Smell and Gum. Hederae very Biting and Exulcerating in Taste Camphore is a Gum out of a Tree like Camphora Poplar It has a strong Smell and tastes Bitterish Acrid Hot and Pungent It is an Antihysterick inwardly and outwardly it opens the Pores in Inflammations and so cools It is us'd as an Alexipharmack It dissolves in Spirit of Wine or Oyl having a great deal of Oyl and Volatile Salt in it A good Tincture is made of it with the Spirit of Wine Tartariz'd Assa Foetida is the most offensive Fetid Assa Foetida like Garlick and very nauseously Bitter It is therefore the greatest Antihysterick Galbanum is very Fetid and smells like Galbanum Garlick It is very Gummy Bitter and Sub-Acrid and therefore very Emollient and Discussing and inwardly Antihysterick It burns like Resin and is Soft and Gummy like Wax Gum-Ammoniack is a Gum of a Ferula Ammoniacum It smells strong and but little like Castor It is very Gummy and Bitter by which it opens all Obstructions cures the Asthma and Fits of the Mother and by the Gumminess and Bitterness is Laxative and Carminative Outwardly by the same it discusses and softens Scirrhous Tumors Soot I place it here because it has Fuligo a Smoaky Fetidness of Burnt Wood and an Oyl and an Acid in it by which it is manifestly Bitter and Acrid It is very Sudorifick inwardly and seems a State of Vegetable Principles betwixt Bitter and Salt. A great Quantity of Earth rises with the Oyly Acid Particles by a stricter Union whereof a Volatile Salt is produced from Soot in Distillation I could not find much Difference in the Taste of Soot of Wood from that of Coals The Last is more Fetid and Saltish the First more Acid. Wood distilled yields a Fetid Oyl and Smoaky Acid The same separated by a Fire from Wood carries Earthy Ashes with it and constitutes Soot which is not very Bitter The Soot of Coal and Wood being almost the same I suppose the Oyl and Acid in the Principles of Vegetables and Minerals are nearly related CHAP. III. Of Turpentine Gum-Resins REsins melt with Heat burn with a Flame and will be easily dried to Powder They dissolve in Oyl or Spirit of Wine They generally taste Brittle and smell of Turpentine or else are more Aromatick or Fetid And some have a Gum joyn'd to the Resin and are call'd Gum Resins Resins are Oyls and Volatile Salts coagulated by an Acid which all Resins yield in Distillation They are Acid-Oleous Liquors at first being originally Turpentines Dr. Grew Fine Frankincense tastes Gummy Hot Olibanum and Bitterish and smells of Turpentine It stops Rheums by the Gumminess and is Diuretick by the Turpentine-Smell and by the Heat dries much and provokes Sweat in a Peripneumonia Mastich has a Turpentine-Smell and Mastiche tastes Hot Gummy and Brittle It is us'd as an Astringent By the Gumminess it stops Rheums The Mastich-Wood is Bitterish and Styptick This is a Terebinthinate-Tree Common Resin tastes Brittle and is of a Resina Turpentine-Smell Resin Mastich and Olibanum have no quantity of a Fixt Salt but yield a Salso-Acrid Spirit or Salt as Succinum Colophonia is Resin of the Firr-Tree boiled Colophonia Resins digest by their moderate Heat and agglutinate by their Gumminess Gum-Juniper is a Gum-Resin of a sort Gum Juniperi of Cedar and smells strong of Turpentine Pitch is of the Nature of Resin Pix CHAP. IV. Of Gum-Resins MYrrh is of a very bitter Taste Myrrha Gummy and Resinous It dissolves best in Spirit of Wine It agglutinates and cleanses in Vlcers Inwardly it is an Vterine Pectoral and Antifebrifick It is the best cleansing Vterine given to half a Scruple Amber tastes Brittle and Resinous and Succinum
Martis and Saccharum Saturni for which reason the haematites is supposed to partake of both Metals and its Vertue lies in the Astringency The Magnet is used in Wounds and all Martial Medicines but neither this nor the haematites nor the Ore of Iron ferment with Acids Amber and other Bitumens attract by their Sulphureous Steams for rubbing increases their Electrical Vertue by exciting the motion of the Sulphureous Effluviums The Load-stone being Iron must attract by its Sulphur Effluvia of which Iron smells strongly And those circulate through the Stony matter with some respect to the Poles to which the Materia subtilis determines it The Pyrites tastes Vitriolick and smells Sulphureous It is the Mysy Diascoridis The Copper-stones are of a Sulphureous burning heat and Vitriolick Taste Lapis Lazuli and Armeni are Vitriolick Purgers and vomit sometimes They are washed to abate their Acrimony They are sensible of Acids and Urinous Spirits extract a blue colour by which it appears That Copper may be dissolved in the Stomach and thereby those Stones purge Smiris contains Iron and its Tincture turns black with Galls Mr. Boyle Pumex is a soft Stone but out of it a Copper Tincture may be extracted whereby it dries and cicatrises 4. Stones of a Bituminous Smell as Gagates Lithanthrax The white Belearnites is mentioned to smell like Amber but the Ash coloured like Cows-Horn as Dr. Grew observed Lapis Lyncis tastes Fetid and smells Sulphureous and therefore is not fit for inward use as a Diuretick It is described of an Electrical Vertue There are some Stones indissolvable by Acids neither melt by the Fire and therefore they consist of an Earthy Principle alone without the mixture of Oyl or Acids as Talc and Selenites or Specular Stone both are used only as Cosmeticks Burnt Minerals and Stones retain the Particles of Fire whereby their weight is increased and they acquire a heating and drying Faculty Magisteries of Stones ferment neither with Alkalin or Acid and therefore are little esteemed Stones dissolved by Acids are Styptick and Coral Austere The Tincture of Coral is binding and rough in Taste and no other Vertue can be expected from a petrified Substance in Tincture though the Chymists unjustly boast of it and have writ so much about its Tincture Lead-spar burnt yields a Lixivial Salt as Dr. Grew affirms The Powder of it unburnt is good for the Stone and Gravel as I have observed all gritty Powders pass by Vrine as Crabs-Eyes c. These are the chief parts of Salt to which an Oyly Acid joyns it self for compounding a Salt. Of the Tastes and Smells of Metals and Metallick Bodies and their products as Vitriols Calces Sulphurs and Bitumens ALL Metals taste something Vitriolick by reason of their Sulphureous Acid. In their Composition there is little Water much Earth and Sulphur which last is compounded of an Oyl and Acid. All Metals have the same Principles but in different proportions and mixtures of them And we may evidently smell the Sulphur in all Metals except in Gold which does not smell Sulphureous Metals have little Taste or Vertue of themselves but by their Preparation First Of Vitriols 1. Of the Taste and Vertue of Gold Medicines Le Mort in his Pharmacia Rationalis gives the taste of the Tincture of Gold and says It is a little Styptick and afterward very Sweet the sweetness following the Vitriolick Taste This Vitriolick sweet Taste agrees exactly with the Steel-Taste of Blood and therefore may be a great Medicine for the strengthning of the Blood as all Steel Medicines be which have also a sweet Vitriolick Taste Mr. Molt an Ingenious Chymist informs me That his Tincture of Gold tastes like Spiritus nitri dulcis therefore this Preparation is different from the former The Volatile Alkali which extracts the Tincture acquires the nature of an Ammoniac Salt by mixing with some of the Acid Menstruum adhering to the Calx of Gold and that Salt may render the Tincture Diuretick and Sudorifick There is in the Blood an Ammoniac Salt besides the Vitriolick Taste And in all these the Tincture of Gold and the Flowers of Sal Ammoniac Martiale agree with the natural Taste of Blood and therefore very much help its digestion and the sanguification of Chyle The Sulphur of Gold cannot be extracted but may produce some effects like Sulphur so the Sulphur of Flint and Iron may appear burning by striking both together which excites a brisk motion And Iron looks of different colours by different degrees of Heat The detonation of Metal their smell of Sulphur and also their burning are plainly effects of their extraverted Sulphur though that cannot be divided from the other Principles Aurum fulminans has a Vitriolick Taste and purges if unwashed and colours the Stools black It yields a purple Sublimate like the solution of Gold this colour proceeds from its Sulphur but that is not separable from the Earthy parts for the Tincture of Gold may be reduced into Gold again The fulminating Vertue depends on a new Nitre regenerated by a mixture of the Salt of Tartar with the Menstruum and this is lodged in the Pores of the Gold and thence exploded 2. Silver Medicines The Crystals which are the Vitriol of Silver are accounted very Bitter In the Pil. Lunares they purge violently The blue Tincture of Silver tastes Bitterish by which and the Volatile Alkali of its Menstruum it is Antiepileptick and it tastes also Styptick for which it is used in the Gonorrhoea 3. Copper Medicines are Vitriolick Bitterish of a Brass-savour Taste very Nauseous The Roman Vitriol is most Acrid Copper Ore and all Copper Medicines have a strong Sulphureous Smell by which they discuss and deterge and eat proud Flesh as Aerugo does but the Vitriolick Taste cicatrizes Galen mentions the Acrimony of Copper Vitriol with a suffocating Smell Spirit of Verdigriese has a strong Acid pungent Taste by which it is a great dissolvent and smells of a quick Acid. Sal Vitrioli vomits by its Brass-savored nauseous Vitriol-Taste White Vitriol will not coagulate the Serum of the Blood neither will burnt Vitriol I mixed both with it but Roman Vitriol curdles it Aes ustum must be drying and Astringent in Taste Sulphur Vitrioli narcoticum tastes Vitriolick The Sulphur in all Vitriols when it is precipitated from the Acid smells Fetid as in Oyl of Vitriol and thereby it becomes Narcotick or Anodyne Copper has a very strong Sulphur whereby it becomes inflammable and very prejudicial to the Miners A Copper-Farthing swallowed by a Child caused a large Salivation The Lunar Caustick tastes of a Brass-savored burning Vitriol as a Chirurgeon informs me Burnt Alum and Lime have also a burning Stypticity and are thereby also very Corrosive Common Verdigriese coagulates the Serum of the Blood into which I put some of it and therefore it acts the same on the Succus nutritius which is bred from the Serum and flows from Vlcers and therefore by this Vitriolick coagulative Vertue
