head and neck favors this view, also its attachment to the 
mesentery. It is, besides, a wide-spread form among the lower 
animals. Yours respectfully, 
W. R. Birds all. 
The death of the two valuable animals, likely to be followed 
by that of others of the same family, which are kept in close 
proximity to the ground where these were placed, induced me to 
inquire as to the cause of the presence of the parasites and of the 
source whence they came. Suspecting that the tape worms 
which they give rise to, might be the cause of it, and that these 
tenias being deposited in the food, grass or water these ruminants 
partook off, I suggested the propriety of examining the rats 
which crawl about those places, and to see if in those I could not 
tind the starting cause of the trouble. After waiting a few days 
a rat killed on those grounds was brought to me. Mr. A. 
McKenzie, student at the College, made a careful post-mortem 
examination of its whole intestinal canal, and the result was the 
discovery of a large number of tape worms, the true nature of 
which however, Dr. Birdsall is inclined to consider as of a differ¬ 
ent origin than the cysticercus tenuicollis. Further investiga¬ 
tions remain to be made, and if the two parasites can be con¬ 
nected, the remedy is plain of itself; get rid of the rats and the 
ruminants will escape the fearful death which threatens them. 
But unfortunately the advice is much easier to give than the 
appplication is to follow.

Mr. Fresident and Gentlemen of the Association : 
The case I am about to describe to you was of much interest 
to me, and I hope it may elicit some remarks as to the treatment
