of relief, the accumulated contents of the ftomach, 

 after diftreffing that organ fome hours, pafs into the 

 inteftines, where the weight adds flill greater diftrefs, 

 producing fometimes cotlivenefs, and not unfre- 

 quently cholic. 



Being perfeftly convinced of thefe circumftances, 

 I have long been in the habit of recommending for 

 dogs thus fituated, once or twice a week, an artifi- 

 cial vomit; and where it has been regularly pcrfifted 

 in, it has been attended with the moft beneficial 

 efteds. Dogs beginning to get purfive, and fat, have 

 been kept by this means in moderate cafe ; and the 

 early Hate of difeafed cheft, producing fliort breath 

 and conftant cough, has been removed. That con- 

 flant ficknefs^ likewife, united with cough, in which 

 a dog, after fome violent efforts, brings up froth 

 alone, has been done away by a regular emetic now 

 and then. 



I have tried for this artificial emetic all the various 

 fubfiances ufed in common as emetics among our- 

 felves; but I found that fome of them afted too 

 roughly, and hence defeated their own ends; while 

 others that were more mild were uncertain in their 

 effects : this fet me upon more clofely imitating na- 

 ture, and extrading the virtues of the dog grafs from 

 the plant itfelf ; and which fo completely anfwered 

 my expectation, that I have ever fince invariably 

 ufed it.
