Report of the Laboratory of Comparative Path- 
ology FOR THE Year Ending February 28th, 
1915. 
The mortality in the Garden for this fiscal year has 
been important both in the number of autopsies (352) 
and the character of animals dying in the collection. 
The number of deaths was considerably swollen by 
reason of an epidemic of infectious enteritis among 
newly imported quail. Aside from this, the number is 
greater than that reported in 1914, but about the same 
as in previous years. Among the important animals 
lost are the Indian elephant Empress/' a Leche ante- 
lope, a sun bear, a Livingstone's eland, an Indian coucal, 
a huanaco, a Tasmanian devil, and a giant salamander. 
Empress" had suffered from a mild rheumatic 
arthritis for several years; at autopsy it seemed that an 
acute inflammation of the upper bowel had hastened her 
end, for she showed chronic afflictions of several organs, 
such as tuberculosis of the lungs, nephritis and fibroid 
tumors of the ovaries. Could her condition have been 
diagnosed and treated it is doubtful if her life could have 
been greatly prolonged. 
During the year Dr. Weidman has continued to study 
the parasties in addition to the general work of the 
laboratory that he has had time to do. He has reported 
a piece of work entitled A Contribution to the Anatomy 
and Development of Cladorchis Stichorchis Subtri- 
quetrus." He is now investigating the relation of 
lipoids to the local accumulations of adipose tissue so 
frequently seen in wild animals, and the importance of 
the Coccidium bigeminum. 
Dr. Schumann has undertaken to arrange for the 
Laboratory a series of adult and fetal skulls and adult 
female pelves to show the evolution of these parts and 
theif relation to the mechanism of labor. His second 
paper ''The Dynamics of the Female Pelvis; Its Evolu- 
tion and Architecture with Respect to Function" has 
been published in the American Journal of Obstetrics and
