The horse to have bran mashes, gentle exercise, and 

 well clothed. 



Diarrhea. 



Causes. — This disorder may proceed from a defective 

 perspiration, from an increased secretion of bile, from 

 too violent exertion, or from hard riding, over feeding, 

 or eating unwholesome food, and sometimes from a 

 morbid change in the secretion of the stomach and 

 intestines. It may also proceed from drinking imme- 

 diately of cold water when heated, or occasionally from 

 worms; sometimes it is the critical termination of a 

 disease, in which case it proves salutary, and ought not 

 be suddenly checked. 



Symptoms. — This disease is indicated by a constant 

 and copious discharge of dung, accompanied with pain, 

 restlessness, and loss of appetite. As the disorder in- 

 creases, the discharge is chiefly mucous, or mixed with 

 small hard lumps of dun g, covered with greasy matter. 

 "When this disease has been neglected, and evacuation 

 becomes involuntary, attended with coldness of the 

 extremeties, a fatal termination will generally ensue. 

 This disease is most prevalent in winter or cold weather. 



Cure. — Both astringents and violent purges are 

 improper in this disease — such medicine as invigorates 

 the intestines should only be employed ; a drink may be 

 given every morning, for two or three mornings, 

 composed of 



Castor Oil 6 ounces. 



Tincture of Opium ^ „ 



In two quarts of thick gruel.
