Foremost among these may be mentioned the Orang Utan, Striped 

 Hyaena, Pacific Walrus, Cheetah and Florida Crocodile. 



In the department of paleontology much valuable work has been 

 accomplished. The large slabs containing the Icthyosauri have 

 been removed from the old vestibule to the entrance of the new 

 Museum on Nineteenth Street, where they can be seen to much bet- 

 ter advantage. 



The collection of vertebrate remains from the Port Kennedy Bone 

 Cave, upon which Professor Cope did his last scientific work, has 

 been displayed in the Pennsylvania and New Jersey Room. The 

 entire collection of American invertebrate fossils has been rear- 

 ranged during the year, and placed in systematic order as regards 

 horizons, while upward of twelve hundred specimens have been 

 cleaned and placed in trays. 



Work on the Isaac Lea Eocene Collection has progressed regu- 

 larly during the year, through the liberality of the Rev. L. T. 

 Chamberlain, D. D. Mr. C. W. Johnson has been engaged in 

 arranging the display collection, which has been increased to fill 

 an additional case provided by Dr. Chamberlain early in the year. 



Mr. Johnson and Mr. Burns have also done a considerable 

 amount of field work which has added richly to the collection. 



Miss Anna T. Jeanes has presented two horizontal oak cases, 

 which have been placed on the first floor of the new museum, in 

 which a synoptical collection of minerals has been arranged for the 

 benefit of students, while a portion of the old collection of minerals, 

 which it is not desired to exbibit, has been stored underneath in the 

 drawers. 



A collection of rocks from Philadelphia and vicinity, selected 

 mainly from the State Geological Survey Collection, has been ar- 

 ranged in the Pennsylvania and New Jersey Room, and a synopti- 

 cal collection of rocks has been arranged in two cases in the old 

 museum, both of which will prove of assistance to students of geol- 

 ogy. 



Four additional cases have been added to the William S. Vaux 

 Collection for the accommodation of exceptionally large crystals and 

 masses of minerals, and an additional case to the Clarence B. Moore 

 Archaeological Collection. Mr. Moore has spent much time in the 

 field during the year, and has added many rare and interesting spe- 

 cimens to this collection. 



The conchological department has continued to increase under 

 the constant care of the professor in that department, and the rear-
