120 NEW YORK ZOOLOGICAL SOCIETY 
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 receint of a specimen of Crypturus 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.
