Gratifying progress is to be reported from the department 

 of Neuor-anatomy. Professor Tilney's technician, Miss Unger, 

 has completed during the year the task of serially sectioning the 

 brain of the gorilla "Dinah." This invaluable and unique speci- 

 men is now, after the taking of the surface records, measure- 

 ments and photographs, in a complete series of about 1,560 sec- 

 tions, of which every fifth section is mounted with a Weigert 

 stain. Together with the brains of chimpanzee, orang and Hylo- 

 bates, treated by the same method, this material will furnish the 

 basis for an exhaustive study of the neural architectonics in the 

 Anthropomorpha. 



During the year Mr. Camp, from the American Museum of 

 Natural History, used the material received in a study of the 

 Carnivore, Marsupial and Primate myology of the pectoral and 

 pelvic girdles and the extremities. 



The receipt of a specimen of Crijpturus cinnamomeus af- 

 forded an opportunity for investigating and assembling the stru- 

 thious characters of this group. 



In spite of the unavoidable reduction in the number and 

 range of the specimens caused by the war, the year has been 

 productive and satisfactory. 



Respectfully submitted, 



George S. Huntington, 

 Prosector, New York Zoological Society.
