APPEJ^DIX C. 
Philadelphia, March 1st, 1881. 
To the Board of Directors of the Zoological Society of Phila- 
delphia. 
Gentlemen : — I have the honor of presenting the follow- 
ing report of the cause of death of the animals that have 
died during the past year in the Garden, and which were 
submitted to me for examination by the Superintendent. 
I take pleasure in calling the attention of your Board to the 
greatly diminished mortality as compared with that of 
former years, and of other Gardens, notwithstanding the 
very severe and unusual season just passed through. I 
attribute this to the steady and continued improvement in 
the internal management of the menagerie. Such deaths 
as have occurred are incidental to the nature of the condi- 
tions often otherwise than natural to which animals are 
subjected in confinement and which neither the foresight 
nor the prudence of the best manager can avert. I take 
this opportunity of stating that whatever of scientific 
interest was found in connection with the post-mortem ex- 
aminaiiions was communicated to the Academy of Natural 
Sciences of this city, and was published and illustrated in 
the Proceedings and Journal of that Institution. The most 
important of such papers were the Structure of the Orang, 
Generative apparatus of Elephant, &c.
