REPORT OF THE 

 PROSECTOR 



TO THE BOARD OF MANAGERS. 



I BEG to submit the following report on the operations of 

 the Prosector's department for the period from December 

 31, 1914, to January 1, 1916: 



Material received. — A total of 225 specimens, divided as 

 follows : 



Primates 62 Cetaceans 2 



Carnivores 39 Birds 43 



Ungulates 19 Reptiles 17 



Rodents 24 Fish 2 



Edentates 7 



Marsupials 10 Total 225 



This material has, as heretofore, been used in the research 

 work of the Anatomical Department of Columbia University. 



1. The brain has been removed and preserved in ail forms 

 by Professor Tilney and Dr. Smith. The former has extended 

 his researches on the morphology of the hypophysis, already 

 published in part, to the important new forms received during 

 the past year. 



The Department of Neurology is undertaking an extensive 

 research on the architectonics of the primate brain in serial 

 sections, with a detailed study of the fibre tracts. The unusual 

 number of primate brains received from the Zoological Society 

 during the year has greatly aided this important investigation. 

 The anthropoid brains have been of especial value, including 

 several specimens of the orang and one each of gorilla and 

 hoolock gibbon. 



2. The Prosector and Professor Schulte have continued 

 their investigation into the morphology of the mammalian 

 salivary structures, extending the same to include the avian and 

 reptilian forms. The earlier results of this research were pub- 

 lished as Vol. IV, under the George Crocker Special Research 

 Fund of Columbia University in 1913. The material received 

 and studied since then is now awaiting the opportunity of a 

 second publication on the subject.
