REPORT OF 

 THE PATHOLOGIST 



TO THE BOARD OF MANAGERS 



DURING 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
