REPORT OF THE 

 PROSECTOR OF THE ZOOLOGICAL SOCIETY. 



I BEG to submit the following report of the Prosector's De- 

 partment of the New York Zoological Society, for the period 

 from May 27, 1913, to February 14, 1914 : 



Material Received. — Two hundred and ten (210) animals 

 have been received from the Zoological Park, distributed as 

 follows : 



Amphibians 5 Mammals 



Reptiles Marsupials 4 



Lizards 7 Insectivores 3 



Tortoises 5 Rodents 17 



Snakes 57 Ungulates 12 



Alligator 1 Carnivores 22 



Birds 48 Primates 29 



Treatment of Material. — The routine treatment of the ma- 

 terial has been an intra-arterial injection of the Lefkowski fluid 

 on receipt of the animal at the laboratory. This has been fol- 

 lowed on the succeeding day by a gelatin injection of the vascu- 

 lar system; after this a general examination of the body was 

 made, and the pathological protocol taken when asked for by the 

 medical department. 



Use of Material. — The material has been used both for the 

 general morphological investigation of the individual forms, and 

 in furtherance of the special lines of research, now under way 

 in the laboratory. The latter have comprised the following 

 topics : 



1. The Prosector and Professor Schulte have made an ex- 

 tensive addition to the research on the structure of the salivary 

 glands, which has been carried on for a number of years pre- 

 viously. The new material received from the Society has added 

 a number of highly important observations to this subject, which 

 the department hopes to publish in the near future. A copy of 

 the previous work on the salivary morphogenesis of the mam- 

 mals is enclosed under separate cover for the Library of the 

 Zoological Society.
