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 begintoshow signs 
of life and in about seven months contain embryo 
worms one one hundred and twentieth of an inch 
inlength. 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 cedaz 
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.
