140 ON THE STABLE. 



the pores of the skin, which, when the animal 



is at rest, and not kept too close, is insensible 



to our organs; but when he is put into violent 



motion, or kept too hot, it becomes sensible in 



the form of sweat, or of steams issuing from his 



skin. 



The sensible perspiration is greatly augment- 

 ed whenever the air surrounding him is not 

 changed sufficiently quickly to enable it to ab- 

 sorb the moisture as it is perspired*, therefore 

 when the horse goes with the wind, he sweats 

 more than when he goes against it, because, in 

 the first instance, he is constantly surrounded by 

 the vapour which flies off from the surface of his 

 body, whereas, in the latter case, the wind, 

 .meeting him, drives it behind him. 



* Hence it is that, in hunting, the best scenting morn- 

 ings are the most fatiguing to horses, for the same mois- 

 ture of the air which suffers the scent to lie on the earth, 

 prevents absorption of the sweat from the body of the 

 horse.
