556 PROCEEDINGS OF THE ACADEMY OF [Dec, 



.Modern cases arc 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, and 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 Red River, Arkansas. 



The removal of the William S. Vaux 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 Messrs. 

 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.
