Man lofes that Way, <vix. thro' tlie Pores of the 

 Skin, even the Weight of himfelf. And I ?.m fare 

 that a Horfe mull lofe more in Proportion to his 

 Bulk by infenfible Perfpiraticn than Man, by rea- 

 fon that the other common Evacuations are not en- 

 joy'd by him in fo great a Degree as in us ; parti- 

 cularly the Evacuation by the Mouth is much lefs 

 in a Horfe than a Man : And if Nature be over- 

 burthen'd, this Creature cannot difcharge himfelf 

 by Vomit ; therefore is he furnifh'd \^ith a Hide 

 exceeding porous in order for a Difcharge of any 

 peccant or offending Matter which might diilurb 

 the Vital Flame. And that this is the Cafe is plain 

 from the Ufes fuch Leather is put to ; for it is not 

 of fo firm a Contexture as to ferve for Shoe-Soles, 

 or the like. 



The Subje6l of Infenfthh Perfpiration is m.ofl cer- 

 tainly of the utmoll Concern, and ought throughly 

 t-o be underflood both by Phyficians and Farriers ; 

 and they ought not only to acquaint themfelves 

 v/ith the Nature of this Evacuation, but likevvife 

 throughly to know by what Means it is to be pro- 

 moted or lelTen'd, according to the feveral Exigen- 

 ces of the Creature they have to deal with, either 

 for the Prefervation or Recovery of Health. 



Infe-nfible Perfptration is either made by the Pores 

 of the Body, which is all over perfpirable, and 

 cover'd with a Skin like a Net ; or it is p>erform'd 

 by Refpiration thro' the Mouth, which lafl in a 

 Man in Health amounts to about half a Pound in 

 the Space of twelve Hours, as has been made to 

 appear by breathing upon a Glafs for that Time. 



By the Pores we are to underrtand the Excretory 

 or difcharging Du6ls or Pipes of the cutaneous 

 Infenfible Glands or Glands of the Skin, both thofe internal, 

 Pcrip-ra- as of the Guts and Vifcera, and the common Co- 

 tion hin- vcrings of all the Mufcles ; as well as the external 

 caulcs ^^^^^ ^^ ^^^ Cuticida or outward Skin. And Na- 



Gr;piiigs, ^^'"^ ^^^ ^o provided, that if by any external Caufe 

 c^f. ' this neceffary Evacuation is hinder'd in any one Part, 



it
