and made it possible to accurately determine some still doubtful 
points. 
4. The entire neuraxis was removed in excellent condition 
for histological study and is now being embedded for serial 
section. 
Another accession which should be especially mentioned 
in this report is the recent receipt of a foetus near term of 
the pigmy sperm whale, Kogia breviceps. This unique specimen 
the Prosector owes to the scientific interest and liberality of 
Prof. F. A. Lucas, Director of the American Museum of Natural 
History. It was removed from the uterus of an adult purchased 
by the Museum and reached the laboratory in perfect condition. 
Many of the anatomical structural details of this whale are 
either unknown at the present time or very imperfectly deter- 
mined. It is hoped that the receipt of this fresh and well-preserved 
material will make an important scientific contribution to this 
subject possible. The study of the head, including the nasal 
passage and the larynx, has been placed in the charge of Dr. J. D. 
Kernan, who has already published his observations on the soft 
parts of Kogia and other cetacean material in the “Annals of the 
New York Academy of Sciences.” 
The Prosector’s Department keenly realizes that the oppor- 
tunity for the study of two immature and fresh specimens of 
hippopotamus and Kogia is a most unusual and fortunate occur- 
rence. The unwieldy bulk of the representatives of these types 
which occasionally become available makes a careful and com- 
plete morphological study practically impossible. In these two 
unique specimens, dwarf character and age have both cooperated 
to obviate this difficulty and have made complete fixation of the 
tissues attainable, ensuring a vastly increased range of exact ana- 
tomical investigation. 
The routine work of the Department and the additions to the 
research series have proceeded during the year as outlined in 
previous reports and nave been productive. 
The Prosector takes pleasure in stating that the neurologi- 
cal work under Professor Tilney’s charge has reached a point 
where the Primate series includes complete serial sections of the 
following brains: Gorilla, Orang, Chimpanzee, Gibbon, Macacus, 
Cynocephalus, Cebus, Ateles, Mycetes, Hapale and Lemur.
