REPORT OF 
THE PATHOLOGIST 
TO THE BOARD OF MANAGERS 
URING the last eight or ten years in which I have been 
honored by the appointment as pathologist to the Zoological 
Society this is my first report. As this is the first opportunity 
that I have had of publicly expressing my great appreciation of 
the honor conferred by the Society in appointing me as patholo- 
gist for their great collection of biological specimens, perhaps 
the greatest in the world, I gladly do so now. 
In such a collection, kept under confinement that is unnatural 
to the members of it, many cases of sickness and death must 
occur, so that the opportunity for examinations is exceedingly 
unusual, and to one interested in such work immense possibilities 
are sure to present themselves. I have found this to be the case 
and have not been slow to take advantage of it all, making it the 
sole object of my study and work. 
In doing this, I may say that I have made a collection of 
thousands of specimens that I have tried to mount and preserve 
carefully so that they may be of use in the future as a reference 
for those who necessarily will be engaged in similar work. 
Much of the material, I may say, is new to science, and as 
the tendency of students of biology today is devoted largely to 
an endeavor to discover the cause of disease, not only in mankind 
but also in such creatures as man necessarily comes in contact 
with in the source of his food or drink, etc., it becomes a very 
important study. This fact has been recognized all over the 
world and many of the best minds of today are engaged in such 
work with unusually good results, a fair share of which has 
fallen to men devoted to the study of science in this country. In 
fact, many of the best discoveries of the age in that line have 
fallen to Americans. Since the above facts must be acknowledged
