Material for scientific purposes is being issued from 
autopsy animals as follows: — 
Wistar Institute of Anatomy (Dr. Greenman) . — Brains 
of mammalia. 
University of Pennsylvania — Department of Biology 
(Dr. McClung). — Normal tissues of all kinds, especially 
fresh testes and ovaries. 
Pennsylvania Department of Health (Dr. Dixon). —

A pure culture of Bacillus tetani was obtained from 
the Persian wild ass which died on June 9, 1912. The 
material was obtained from a wound on the flank. 
A pure culture of Bacillus tuberculosis has been ob- 
tained from an ischio-rectal abscess of an American bison 
which died on August 7, 1912. The virus passed through 
man and guinea pig, the former having been accidentally 
inoculated at autopsy, the latter with material from the 
infected human wound. 
The common occurrence of parasitic cysts in the rumi- 
nants aroused the suspicion that the Canidoe, opposite 
whose dens the deer and camel are parked, might be the 
disseminators of the disease. The feces of these canines 
(15) were examined. Only two animals were found in- 
fested, as follows: — 
1. Red Fox. — Ascaris and trichocephalus, 
2. Gray Wolf (No. 3).—Cestode ova. 
The parasite found in the last-named animal is the adult 
form of that found in our ruminants at autopsy, and this 
wolf could easily have been the source of this infection. 
It has been isolated and is receiving treatment. 
Endocarditis. 
This year we have had but two cases of endocarditis 
in the opossums, although seven have died (2544, 2550).
