after a good dose of castor oil, to free tlie bowel from of- 

 fending matter, if such there be. This is a safe proced-

 by mechanical means. Castor oil or syrup of buckthorn 

 may be given by the mouth. Kneading the abdomen may

 opposite kind, tends to constipate. Exercise and a suitable 

 diet remedy the irregularity in most dogs. In old animals 

 the muscular coat of the intestine loses tone, and then 

 medicine and massage of the abdomen is demanded. A 

 pill made as follows will possibly do good :
