PROCEEDINGS OF THE ACADEMY OF 
[Dec., 
Modem cases are much needed in the northern museum, which 
has been fire-proofed and much improved in arrangement. With 
financial help, this wing can be made one of the most attractive in 
the museum. 
The indirect lighting system employed will enable us, during this 
coming year, to display our exhibits on certain evenings in the month, 
so that those engaged throughout the day may make their studies in 
the various divisions of natural history in which they are interested. 
The William S. Vaux Collection of minerals is being moved into 
the old library hall, which will relieve the crowding in the archaeo¬ 
logical collection and enable the Academy to exhibit the general 
mineral collection in near proximity. 
Many valuable specimens have been added during the year. 
Several expeditions have been successfully conducted by our special¬ 
ists, a rich harvest resulting from their research work. 
Among the conspicuous and valuable accessions may be mentioned 
the mounted anthropoids and their respective skeletons, which have 
been added to the Dr. Thomas Biddle Collection. The new speci¬ 
mens were selected by Dr. Biddle to complete as nearly as possible 
the anthropoid family. The additions comprise a female and young 
gorilla, a large-eared chimpanzee, a young chimpanzee, an^l a baby 
orang-outang. Several rare monkeys and an Ornithorhynchus were 
also presented by Dr. Biddle. 
Mr. Clarence B. Moore has continued his comprehensive inves¬ 
tigations of the Indian mounds of the southern United States, 
resulting in the acquisition of many valuable specimens which make 
this collection one of the most complete of its kind ever brought to¬ 
gether. Of special interest were two forms of pipes, one of the mono¬ 
ceramic and the other of the smoke-effigy type. A new type of grave 
was discovered on Bed River, Arkansas. 
The removal of the William S. Yaux Mineral Collection from 
the archaeological floor will provide Mr. Moore with additional room 
for the material recently obtained. 
Among other expeditions may be mentioned one by Alessrs. 
Alfred M. Collins and E. Marshall Scull to British East Africa, 
where they collected for the Academy a valuable series of large 
mammals, now being prepared for mounting. The proper arrange¬ 
ment of this collection will demand a new wing to our building. 
Among the most valuable mammals may be mentioned the greater 
and lesser kudu, eland, giraffe, zebra, buffalo, and a variety of 
antelopes, hyenas, etc.
