In some cases the specimens were

Az to the animals containing trichine be-
ing out Of health, the report answers in the
negative, and quotes the following from Van
on the subject: ".They are not
more abundant in delicate individuals than
in thsse who enjoy the most robust health.
On the contrary, all wild animals harbor
heir parasitical worms, and the greater part
them have not lived long in captivity
before nemxtodo aud ceetode worms cem-
disappear" III
AZ proof of this, trichinous pork was fed
to a white rat. A liberal supply of the pab-
ulum was given the animal, and 1t grew
and always enjoyed the best Of
health. The animal was finally killed, and
tue muscles were found to be literally alive
with trichine. Every musc.e was infected
from the tip of the nose TO the end of the
tail.
The only infallible means by which the
meat inspectors can detect the parasite liz

infected meat presents no peculiar appear.

The parasite is not destroyed BY thorough
sailing and smoking, a. is evidenced by the
fact that most Of the cases Of trichinosis in
he western country are traceable to raw
smoked hams. To ascertain whether or not
an infected ham could be rendered harmless,
. series of experiments were instituted in
the physiological laboratory of Rush COL

in snlphurous acid We have an agent which
kills the worms, but readily permeates the
entire ham, and is a. readily expelled. Ow.

In view of the results of the investigs-
items. several important questions suggest
Themselves. /. Why is the percentage OF,
infected hogs SO much greater than it
wss eight years sg0i Az that time q CON-
mittee of the Chicago academy of science
examined q large numner Of hogs, and found
bat 2 per cent infected. We are unable al
present tn offer any satisfactory solution of
this question.
3. Why is the percentage Of infected
hogs 90 much greater here then in Ger
many? Engelbrecht' states that of 1926
hogs examined between October, 1865, and
April, 1873. but seventy were found to con. +

ments which We hope may lead to Q solu-
lion of this problem.
The third and practically most important
query in this: Since 8 per cent of our
hogs are trichinous, why are cases of tri.
90 rare?
We would advance these propositions:
l. That, 10 most instances, the meat lie
previously subjected TO thorough cooking,
the worms are killed.
2. That, in consequence of the close re-
emblance of the symptoms of trichiBosis
0 those induced by other causes-not4bl,

8. That the injection of a certain num-.
