stomach or backwards to the rectum and some- 

 times escapes from the intestine through the anus. 

 This worm has also been found in the biliary duct, 

 gall bladder and the substance of the liver. There 

 has been a number of experiments made to find the 

 origin of this worm, and it is found that the eggs 

 of this worm are passed from the bowel. They re- 

 tain their vitality for a long time; they appear 

 never to be developed in the bowels, but when dis- 

 charged and kept in water they begin to show signs 

 of life and in about seven months contain embryo 

 worms one one hundred and twentieth of an inch 

 in length. These have not been seen to break shell 

 but the ova carried into streams, ponds and wells 

 sometimes probably find an entrance into the stom- 

 ach with the drinking water, when the embryo es- 

 capes from its -shell and completes its growth in 

 the intestine. 



Treament: The best remedy for this worm is 

 the fluid extract of spigelia and senna given in 

 half ounce doses every four hours until it causes 

 purging. Worm seed oil (chenopodium) in doses 

 of from five to ten drops given in a tablespoonful 

 of castor oil is also good. Turpentine in doses of 

 from fifteen to twenty drops three times a day fol- 

 lowed by castor oil or epsom salts is useful. The 

 cedar apple, an excrescence found on the red cedar 

 has been used with good results in doses of from 

 twenty to twenty-five grains of the powder, re- 

 peated three times a -day, followed by a physic.
