GENERAL DISEASES 7 



turpentine, creolin, tar disinfectants, sulphur, etc. 

 Turpentine is the one most used, and is easily dissem- 

 inated by pouring on boiling water or on hot bricks. 

 It is necessary to put the hogs into a tight enclosure, 

 or they will get but little benefit from the vapors. 

 However, care must be taken or the animals may suf- 

 fer from the lack of air. 



Drugs given hy way of the rectum in the form of 

 an injection, enema or clyster, are used for their local 

 effect on the intestine and to accelerate the action of 

 a purgative. 



-It is best to use some form of a fountain syringe 

 in giving a rectal injection. About two feet of rub- 

 ber tubing carrying a funnel at one end wiir answer 

 the purpose very well. In giving an injection, the 

 feces should be first removed from the rectum and 

 the nozzle of the syringe smeared with vaseline be- 

 fore introducing it. From two to four quarts of 

 water may be slowly injected into the intestines of a 

 grown hog. When giving a large injection, it is best 

 to elevate the hind parts, so as to help the water to 

 gravitate forward along the canal.
