CHAP. II.] PERSPIRATION I HIDE-BOUND. 77 



can be understood as well without them, we find 

 less occasion for introducing them here than is 

 generally practised. For, the peculiar nature of 

 the horse having assimilated together, by its action, 

 the three kinds of secretion more so than is the 

 case with other animals ; and his habits contribut- 

 ing as much more to the hasty calling off of one 

 kind of fluid from certain parts to the assistance of 

 another part, which may have been exhausted of 

 its kind ; and as the treatment of the horse in all 

 cases of a disordered secretion of these fluids is the 

 same throughout, the action of medicine upon one 

 always affording assistance to another (as we shall 

 prove shortly), there is no such necessity for car- 

 rying the distinction farther in horse-medicine, 

 although it may be very proper in the human 

 practice. 



Perspiration is always at a great height in the 

 horse ; it is one of the chief means of cure in most 

 of his disorders, and consists in drawing the watery 

 secretions from all parts of the body. These pass to 

 the surface readily, coming through the membranes 

 from the joints, the solids, and even the bowels and 

 their coverings : as may be noticed in the case of 

 hide-bound, upon opening the animals that die in 

 this state of exhausted nature, the mesenteric canal 

 (hereafter described) is invariably discoloured with 

 yellowness, being, at times, nearly orange colour ; 

 but we have almost as constantly found the lacteals 

 of a fine-coated horse shine through as white as 

 milk. Again, on over-working the horse, so much
