70 THE FARMER'S 



ogy of animals differ. For example, the dog has 

 no insensible perspiration. The mouth of the 

 horse performs but one office, that of conveying 

 food to the stomach. It conveys nothing to the 

 lungs or from them. It has nothing to do with the 

 modulation of his voice, as in most quadrupeds and 

 in man. The passages to the lungs and to the 

 stomach in the horse are distinct. 



The horse unlike most other quadrupeds has no 

 gall-bladder, notwithstanding a work which has 

 been through twelve editions, and one at least in 

 this country, (Taplin's Farriery) gives a particular 

 description of the diseases of the gall-bladder, and 

 the symptoms of those diseases. 



It has been, stated above, that the anatomy and 

 physiology of animals differ, so also do their dis- 

 eases. 



The horse is not subject to fever, i, e. he has no 

 simple, idiophatic fever, no cold, hot and sweating 

 stage, as man has. The feverish action, which the 

 heart and arteries of the horse sometimes assume 

 is sympathetic, and is always preceded by some 

 local affection. It is a disease of irritation. 



The eyes of the horse are subject to a species 

 of cataract, that affects no other animal. It arises 

 from a constitutional disease, brought on by bad 

 stabling. It is never produced by local injury. 

 This species of cataract commences with an in- 

 flammation of the conjunctiva, without any appar- 

 ent cause. Local applications have no effect in 

 removing it. The only rational method of treating 

 it is to remo,ve, if possible, the constitutional dis- 

 ease and improve the health and condition of the 

 animal.
