a Management worthy of a Physician; but yet I will appeal to any that are Sober, Calm, and free from Prejudice, whether if they allow that this Exercise, does dispose to Sleep as I affirm, upon this Supposal, any thing can more exactly hit the miserable Circumstances of those Persons. To the Sick, these little things are of great Moment, and in such seemingly little things as these, the Accurate Management of the Ancients consisted, by which they were sometimes enabled to accomplish, that which we, for want of those Measures, do sometimes fall short of. As to the other Property of this Exercise, it may be convenient for me to make some Apology, before I enter upon the Mention of it, because it is such, as cannot be well understood, but by those who are Conversant with _Sanctorius_, upon one of whose above-mention’d Maxims it does depend, _viz._ Upon that which shews the great Increase of the insensible Perspiration by _Pandiculation_ and Gauping; now I hope the taking Notice of this, will not be thought odd in an Age, of which it is one of the Good Qualities, that Men will not take up with the old superficial Way of accounting for things by Occult Qualities, _Putredo_’s, and the like, but enquire into the _Modus_ of the more Abstruse Actions of Nature, and will be convinc’d, that whatever are the legitimate Measures that she takes, they cannot be thought little or uncouth, seeing ’tis by such _Minima_, that she comes to be able to compleat her great Things. If therefore by Gauping, this Perspiration is so very much promoted, as has been discovered, and adjusted by the Experiments of that Admirable Author, we may reflect upon how little things our Deliverance from Feavers, and other Inconveniences, does depend; nothing being more common upon taking Cold, Surfeits, or the like, than for People to Gaup often, till the offensive Matter is let out, and consequently it is very apparent, that whatsoever will promote the Pandiculation must be beneficial, when the Perspiration is obstructed; and this, tho’ it cannot be effected by any Internal, may be done by Riding, which will dispose all People, the Healthy as well the Sick, more or less to it. I know it may be alledg’d, that all People when they are tyr’d, are more or less apt to Gaup and Retch, but yet it cannot be said, that Thirty Miles Riding is a Tyring to a Healthy Man; and yet let any one observe, if that or less will not dispose all People to this Affect, unless they over-rule it by Drinking of great Quantities of good Liquor, which I believe will not always suppress it neither; but for those who are Sickly, the least Use of this Exercise disposes ’em to this Method of Nature, which perhaps no other Exercise will do, unless they are tyr’d by it; which shews how much Riding is preferable to other Exercises for Sick People, because it does some way or other act upon the Secret Springs of Nature, after a more peculiar manner, and therefore more proper for the promoting that
