DISEASES OF THE STOMACH AXD INTESTINES. 387 



horses start well on a journey, but before they have gone any 

 great distance, commence to purge more or less freely. Such 

 horses are hard to keep in condition. 



Symptoms. — The symptoms of diarrhoea are the passing of an 

 undue amount of liquid f?eces. Slight griping pains may be 

 manifested by the animal. The pulse becomes quickened, the 

 animal weakens, and the extremities are colder than natural. 

 Excessive thirst is manifested, and the animal is off his feed. If 

 it be not checked it nuiv terminate in enteritis, or farcy and 

 glanders may supervene. 



Treatment. — Endeavor to find the cause of the trouble. If 

 due to an irritant, it is not safe to check it thoroughly; and on the 

 other hand, if there is great weakness and prostration, it must be 

 checked as soon as possible. "Where nature is throwing off some 

 offending matter, it must be assisted by a dose of linseed oil or 

 castor oil. If there is prostration from undue passage of liquid 

 faeces, it must be checked by giving opiates. The powdered 

 opium should be given in drachm doses three or four times a day. 

 "Where the animal is not too weak, I think it best to administer a 

 pint of oil. In cases where great weakness is noticed, it becomes 

 necessary' to check it at once by giving opiates as above men- 

 tioned. Boiled starch or flour gruel may be allowed the animal 

 to drink, and the food should be of the best kind. If there be 

 much fetor the hyposulphite of soda may be given in the feed in 

 one-half ounce doses. Catechu and powdered chalk are highly 

 beneficial. Prof. Smith recommends the use of catechu, a half 

 ounce to an ounce; gentian, two drachms; ginger two drachms, 

 and repeat in twelve or eighteen hours. Oil of turpentine, one 

 ounce; opium, one drachm, beaten up with two or three eggs, is 

 a good remedy. The intense thirst should not be gratified, and 

 the animal should be allowed to drink only small quantities at 

 a time.
