yards. Early in July, after having drunken of this stagnant water, coming both 
from springs and rains, he was seized with colic which lasted two days and then 
ceased for about tv/o months. Then loss of appetite developed, together with vomit- 
ing after meals; this condition of malaise lasted five days and during the last two 
days was accompanied by colic. On the fifth day, after a light meal, together with 
a drink of pure water, vomiting occurred, resulting in the expulsion of a large female

developed to its present size in the man’s intestine.
