AND RURAL ECONOMIST. 245 



mumber of horses are soiled, a pair of poles, or a hand-cart, 

 will be better than a basket to carry the hay to them. This 

 practice, called soiling, answers well near cities and large 

 towns, where lands for pasturage are not plenty ; and where, 

 by means of the plenty of manure, lands may be made to 

 yield the greatest crops of grass. For very thick grass 

 should not be fed off; because the greater part of it will be 

 wasted by the trampling and the excrements of animals. 



When grain is given to horses it is an economical practice 

 to have it either ground or boiled. When horses are soiled, 

 or fed in a stable on green grass, it should be cut and carried 

 in during the morning while the dew is on. 



A disorder, called 'ptyalism, has for some years past been 

 gaining ground among horses in various parts of the United 

 States, which is an excessive watering or slavering at the 

 mouth. Various causes have been assigned for this disorder, 

 but none of them satisfactory. Soiling them is, however, a 

 certain remedy. 



The following remarks on the diseases of the horse were 

 written by Dr. J. B. Brown, of Boston, and were first pub- 

 lished in the New England Journal of Medicine and Surgery. 



A knowledge of the diseases of animals, in general, cannot 

 be inferred from a knowledge of the diseases of any one par- 

 ticular species of animals. 



Thus he who is acquainted with the diseases of the horse 

 would not from that circumstance be able to prescribe cor- 

 rectly for the disea.ses of quadrupeds generally. The anato- 

 my and physiology of animals differ. For example, the dog 

 has no insensible perspiration. The mouth of the horse per- 

 forms but one office, that of conveying food to the stomach. 

 It conveys nothing to the lungs, or from them. It has no- 

 thing 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 diseases. 



The horse is not subject to fever, that is, he has no simple, 

 idiopathic fever, no cold, hot, and sweating stage, as man 

 has. The feverish action which the heart and arteries of
