these Parts grow accustom’d to the Air, or other Moisture, and receive little or no hinderance in their discharges from it; as we see the Palms of the Hands shall sweat copiously, notwithstanding the External Air immediately striking upon ’em; and none are more Strong and Healthy, than those who are wont to have their Feet wet without changing their Shooes and Stockings for it. The Stomach plac’d in the midst of the Body, and consequently exquisitely warm, is so adapted, as to bear large Draughts of the Coldest Liquor, without the least Damage, unless the Body has been extremely heated; and tho’ its Office seems to require great and continual Heat, yet it is not obstructed in it, by the admission of Cold things, nor are its Glands benumn’d or constring’d, so as to hinder the Secretion of digesting Juices; and can we suppose the Fabrick of the Skin less perfect, and exquisite, when by its position it is to be immediately subject to the effects of the External Air? Can we think its Vessels are not endu’d with a strength sufficient to answer the Force and Weight of the incumbent Air? And its Glands of such a make, as that the Particles they strain shall be of so fine a Texture as to pass the Skin, when it seems to us to be too close to permit any transition? We make but indifferent use of a very good Theory, that _Sanctorius_ has furnish’d us with, if we give way to these Thoughts, and encourage too frequently the promoting of Sensible Perspirations; which, be they in never so small a degree, are the effect of some Violence upon Nature, and consequently not to be compar’d with the other more Even and Regular Secretion.
