en-hundredth of an inch in-thickness coiled up in 
two or three turns; the size of the cyst is about one- 
eighth of an inch long and one one-hundred and 
thirtieth thick. If the flesh of the pig containing 
these worms be eaten by man, they become liber- 
ated in the stomach and, entering the intestine, at- 
tach themselves to its soft lining, and there, sur- 
rounded with abundance of food, they grow very 
rapidly and become mature, with fully developed 
sexual organs, in two days. The females are more 
numerous than the male and become about one 
eighth of an inch long when full grown. They pair 
as scon as mature and the male soon dies, but the 
female begins to give birth to living worms in five 
or six days from the time it enters the stomach and 
lives long enough to produce a brood of from five 
“hundred to one thousand young worms each. As 
one ounce of pork often contains a quarter of a mill- 
ion or more of the worms, it is not surprising that 
the million of adult worms and their offspring 
sometimes resulting from a single meal of raw 
pork should by their presence, produce great irrita- 
tion and inflammation of the intestine and violent 
diarrhea and vomiting, which are often the first 
symptoms in severe cases. But the young worms 
as soon as they are born, begin to eat or force their 
way through the membrane of the intestine into 
the minute blood vessels and other organs, thus 
vastly increasing the irritation. Entering the cir- 
culation they are carried by the blood to the heart, 
thence to the lungs and then become diffused 
through the whole system. (Verrill.) Some other ob-
