 Oil of turpentine is an excellent remedy for all worms which 

 inhabit the digestive canal. It may be given in the dose of i to 

 3 teaspoonfuls, and is best administered by forcing it through a 

 small flexible catheter that has been oiled and passed through 

 the mouth and oesophagus to the crop. This medicine is less 

 severe in its effects if diluted with an equal bulk of olive oil, 

 but, if it fails to destroy the parasites when so diluted, it may be 

 given pure. The method of administering medicine by deposit- 

 ing it directly in the crop can be advantageously used with many 

 other liquid remedies, and should be adopted in all cases where 

 it is important to have the full dose in the stomach in a short 

 time. It does away with the uncertainty attending the giving 

 of medicine in the feed or drinking water, and with a little 

 practice is more expeditious than making and giving pills. The 

 open end of the catheter may be inserted into a rubber bulb 

 having one opening. Just sufficient air should be expelled from 

 the bulb, so that the dose of medicine will be sucked up without
