A60474	Of the unequality of natural time, with its reason and cavses. together with a table of the true æquation of natvral dayes : drawn up chiefly for the use of the gentry, in order to their more true adjusting, and right managing of pendulum clocks, and watches / by John Smith ...

set The same Clock being also set to the Hour on the 4th of May or the 15th of July shall on the following Year be sometimes too fast and at other times too slow These are all strange and unaccountable things to such as understand not the Nature of the Unequality of Time from whence all these Varieties do still arise and are scarcely to be demonstrated to the Understanding by any other way than by this or some other Table of the Aequation of Time Since therefore there is a necessity for setting Clocks a-new to the Sun at some times that they may be kept as near as possible to the apparent time given by a Dial I advise that this setting may be if possible the first day of every Month so may you the better discern by the Time set down at the bottom of every Column whether your Clock have gone right to the mean time and be as exact in his Motion as 't is possible to bring him to For if it be exactly adjusted it will then either gain or lose near that time that is set down at the bottom of every Month those Sums being nothing else but the Aequations of the whole Month added together into one Summ as before I directed when I gave you the Method of adjusting a Pendulum to the true or mean time But in case you cannot set it right the first day then must you be at a little trouble to add together the Aequations your self at such time as you come to set it a-new but when the Clock is well adjusted there needs little of this trouble being assured that it 's brought to the nearest pitch of Motion it 's capable of and that when it is at any time found to differ from the Sun it must be lookt upon as the natural Consequence of the Unequality of Time and not any Deficiency in the Motion of the Clock I speak this of those long and curious Pendulums that vibrate within the Compass of 2 or 3 Inches for the less Compass a Pendulum takes the more steady is it's Motion not being so subject to rise and fall as others are that vibrate in a larger Compass As for those shorter Pendulums of a Foot long or under although they may go very steady for the most part if Frost or foulness hinder not yet are they not at all intended in this Discourse their Motion being apt to an Alteration in some Cases for a short Pendulum that goes well when clean shall go faster than the mean time when foul because the Pendulum is by the foulness hindred from taking its wonted Compass The same effect does Frost produce for by congealing the Oyl in the Pevets its freedom of Motion is interrupted so that the Pendulum not fetching it's wonted Compass shall go too fast but those long and curious Pendulums of 40 Inches that fetch not above three Inches compass they are so exact that being once adjusted they shall alwayes keep the same time if their motion continue for if the Pendulum should fetch a smaller compass their Motion would cease and themselves stand still When such a Pendulum as this is well adjusted you may trust to it as to it's correspondence in Motion with the mean time and only give your self the trouble sometimes to set it a little forward or backward according to what the unequality of Time has made it to differ from the same Dial with which you did use to set it which times of setting may be as I said before once in a Month yet if the Table be well noted you shall find there be some times in the year in which a good Clock may go a longer time without any material difference from the time given by a Dial For Example Suppose you set a Clock right to the Sun the first of January this Clock if let go till the first of March shall then be but two Minutes four Seconds too fast for though it gain in January six Minutes no great matter yet losing in the next Month about four Minutes it shall at the end of that Month be but two Minutes to fast nay if let go another Month as to the last of March is it shall then differ but about seven Minutes which is no great matter Moreover if you set a Clock the first of May it shall if let go till June lose but two Minutes thirty five Seconds in the whole though it shall at the beginning of May be about five Minutes to slow which is no great matter so also if it be set right the first of June it may well go without setting till the first of September for though it gain five Minutes in June yet losing eight Minutes in August it shall then be but about three Minutes too slow in this three Months time but at some other times as from February to May if a Clock were let go 't will be extreamly out losing above eighteen Minutes so also in November December and January in which time it will gain above thirty Minutes By the Table you may also readily find out what difference there is between the lengths of any two daies in this manner First If the daies are both shorter or both longer than the mean day then substract the Equation in the Table belonging to one day from the Equation of the other and the remainder shall shew their difference in length But if the daies be one longer than the mean and the other shorter then add the two Equations together and the summ shall be the time that they differ in length Thus the tenth of January will be found to be thirteen Seconds longer than the tenth of May also the fifteenth of September will be found to be fifty one Seconds shorter than the fifteenth of December Note That if men be very nice in keeping a Clock true to the Sun they should then make use if possible of but one time on the Dial that they set it with and that pretty near noon for few Dials being drawn exactly true great mistakes may arise when a Clock is set to one hour and then compared with another and by reason of refractions great errours may also arise for the Sun by Refractions being made to appear higher than really she is there can be no certain account taken of the time till near Noon where Refractions cease And when all this care is taken in regard it is so very hard to distinguish Minutes by the shadow of a Dial you will be much more exact if you do thus Let two plain and flat plates or boards about ten Inches square be joyned so close together that a Six-pence may but just go between let them be fixed so that this Cranney between them may respect the true South this will give you the time to less than half a Minute by observing the first moment that the Suns beam is darted through it and cast upon some dark body that is plac●d on the North-part to receive the light so that having thus the exact time when the Sun comes to every Meridian it will be found a much better way to adjust Clocks by such a device as this than by the truest Dial. One use more and that a Principal one I shall add that is this When a Clock is once well adjusted to the mean or equal day you may then by this Table keep it right to the time given by the Sun although you never set it right to a Dial nor see the Sun above once a Year to perform this do thus set your Clock right to the Sun the first day of any one Month and then the Table still giving you the time it should lose or gain in that whole Months ●ime 't is then but setting it forward or backward the first day of the next Month what it either hath got or lost in the Month immediately preceding and it will then be right with the Sun as if it had been set by a Dial and so from Month to Month you may by still setting it either forward or backward according to what the Table tells you it will gain or lose keep it true to the time given by the Sun though it should never shine so as to give you an opportunity to set it by a Dial above once in the whole Year but be sure your Clock be first well adjusted or else there may be some errour Note that for this purpose it will be very convenient to Paste the Table it self on a board and then putting it into a handsom Frame let it be hung up near the Clock that you may have ready recourse to it on all occasions especially for this in particular for without the assistance of such a Table as this I know no way in the World to keep a Clock right to the apparent time in case Clouds should intercept the Beams of the Sun for any long time together FINIS BOOKS Sold by Joseph Watts at the Half-moon in St. Paul's Church-yard JOsephus's Wars of the Jews Fol.
