with bicarbonate of soda is given by Schidlowsky 1 in doses up to 

 o-oi to o - o6 grm. three times daily, and a dose of castor oil on the day

 according to age (Bodenstein 6 ). Bn'ining 7 , 8 recommends the so-called 

 American worm-seed oil, derived from a plant native to the United 

 States, Chenopodinm anthelminticum, Gray. It is given in emulsion 

 (ol. chenopodii anthelm. 10*0 grm., vitelli ovi unius, ol. amygcl., gi.

 in these different sites to a whole series of irritative symptoms. In the 

 rectum, also, Oxyuridcz give rise to such symptoms, which are mani-

 intestinal catarrhs are thus explained. The frequent coincidence of 

 haemorrhoidal troubles with Ox\uridcc may be attributed to the fact 

 that the veins of the rectum participate in those changes which have
