APPENDIX C. 
To ilie Board of Directors of 
The Zoological Society of Philadelphia : 
Gentlemen: — I have the honor of presenting my 
report as Prosector of the Society.

paring the tabular list of the animals which have died in 
the garden, and sent to me for examination by the Superin-

preceding report — it will be seen that the causes of death 
are generally the same — usually unavoidable — being evils 
inherent to the nature of animals in Zoological Gardens. 
Where no organic disease is specified the animal seems to 
have simply wasted away. As regards the disposition of 
the remains, whenever anything valuable presented itself 
it was preserved, prepared, and deposited either in the 
Museum of the University of Pennsylvania, or that of the 
Academy of Natural Sciences. Among those specimens, 
in addition to skeletons, viscerae, etc., may be mentioned a 
collection of brains, which have been photographed by Dr. 
Andrew Parker, and made use of as the basis of his prize 
essay on the " Convolutions of the Brain," recommended for 
publication by the Faculty of the University. 
Below will be found the list of animals which have been 
subjected to me for examination: —
