VERMINOUS DISEASES. 295 



coats of the bowel being stimulated, it should con- 

 tract hastily and expel the glyster, Avhich acts with 

 more certainty, if it remains for some time. This 

 operation, repeated for a few successive days, will 

 seldom fail to remove, for a time, the ascarides and 

 the symptoms they produce. 



Purgatives employed alone are of little service ; 

 but during the use of the glysters they ought to be 

 occasionally exhibited." 



Of these worms Dr. Fisher says, " they reside 

 principally in the rectum. A brisk cathartic will 

 remove part of them ; but medicines which have to 

 pass through the stomach cannot be depended on. 

 Anthelmintic enemas, such as oil, a solution of sal. 

 marin. or sal. martis, repeated once in a day or 

 two, for five or six times, very seldom fail of des- 

 troying them." 



A medical friend of mine was lately entirely re- 

 leived from a violent irritation of the rectum from 

 these worms, by introducing once only a sort of 

 large bougie into the bowel, smeared with whale 

 oil. In these cases, if other remedies fail, the spir-. 

 it of turpentine should be tried. If it should pro- 

 duce any considerable pain of the rectum, this in- 

 convenience might be easily removed by some mu- 

 cilaginous injections ; or by castor oil taken by the 

 mouth. The oil might be previously taken, and the 

 turpentine injected half an hour before the oil would- 

 be expected to operate.]
