This material has, as in the past, been utilized for three 
purposes: 
1. Investigation—tThe receipt of some much desired forms, 
especially among Primates and Marsupials, has enabled the De- 
partment to practically complete the detailed work on the mor- 
phology and phylogeny of the mammalian respiratory tract, 
which has been prosecuted for a number of years. As soon as 
the question of adequate illustration can be met satisfactorily, 
the Memoir will be published through the Wistar Institute of 
Philadelphia. 
A number of forms of great value and importance to the 
continued investigation of the salivary structures were obtained 
and prepared during the year. It is hoped that the Department 
will be able to issue in the near future a publication supplemen- 
tary to the volume which has already appeared on this subject. 
The brains of all specimens received in sufficiently fresh con- 
dition have been intrusted to Professor Tilney for neurological 
investigation.
