a few examples. I showed a case of mayhem in an ocelot 
possibly due to heavy infestation with lice, multiple 
tumors in a jaguar and discussed the development of 
pneumonia in birds and mammals. In the latter, the 
exact method of the production of pneumonia cannot 
be said to have been seen whereas the simpler construction 
of the avian lung permits one to trace the disease process 
from the bronchial tubes into the respiratory spaces 
proper, or if the disease virus come via the blood, from 
deep in the lung to the bronchi. This will be published 
later. 
Dr. Corson- White has ready for publication two papers, 
one upon the incidence and cause of osteomalacia and 
rickets in the lower animals, the other upon osteitis 
deformans in monkeys. I read before the College of 
Physicans of Philadelphia on December 7, a paper upon 
the Comparative Pathology of the Heart. The work, 
which will be published, goes to show that the large 
heart of the bird does not become diseased or enlarged 
as readily as the relatively smaller heart of the mammal. 
The following is a list of the animals dying during the 
year. The total will be found not to tally with the re- 
cords upon the table as some specimens have died from 
injury and some were decomposed. Moreover, in many 
instances animals are included in the figures of more 
than one heading since lesions of importance may have 
been found in more that one of the systems. It is 
seldom the case that only one of the systems is sufficiently 
affected to be the only cause of death.
