The section of the basement of the new building in which the alco- 

 hohc collections are arranged has been materially enlarged to relieve 

 its overcrowded condition. The alcoholic mammals have been 

 entirely rearranged. 



Improvements have been made to the steam-heating plant by the 

 addition of radiators in the old building, and the elevator in the new 

 musevun has been altered to meet requirements of the municipal laws. 

 An additional watchman has been employed. 



Messrs. Henry W. Fowler and James A. G. Rehn have been added 

 during the year to the staff of ^Museum assistants. Mr. Fowler has 

 made important progress in the rearrangement of the general collection 

 of fishes, but has devoted most of his time to identifying the large 

 Sumatran collection recently received from "Sir. Alfred C. Harrison, Jr., 

 and Dr. H. M. Hiller. ^Ir. Rehn, besides assisting in various depart- 

 ments, has arranged and catalogued the Rhoads collection of mammals, 

 brino-ing the entire series of the smaller mammalian skins into excel- 

 lent order. 



Details of the year's work will be found in the appended reports 

 of the sections. 



Dr. Moore has continued his work on the helminthological collection 

 during the year, and Miss Wardle has made considerable advance 

 in the cataloguing and arranging of the archa:>ological material. 



During the spring Dr. H. A. Pilsbry made a trip through portions of 

 Arkansas, Indian Territory and Texas in the interests of the Academy 

 and secured valuable series of mollusks, reptiles and plants, many of 

 which were new to the collection. 



Mr. Clarence B. Moore has continued to add to his unique and com- 

 prehensive collection of Indian antiquities from Florida and Georgia. 

 His expedition of last winter proved to be unusually successful and 

 the results make his department one of the most important in the 

 Museimi. 



Most notal^le among the many additions to the zoological depart- 

 ment was the magnificent collection of mounted anthropoid apes and 

 skeletons presented to the Academy by Dr. Thomas Biddle. 



A valuable series of fishes, which fills many gaps in our collection, 

 was presented by the U. S. Fish Commission. 



Dr. Henry C. Chapman has added a large number of specimens to the 

 collection of marine invertebrates previously presented by him, and 

 Mr. Joseph Willcox has contributed a notable series of fossil mollusks 

 from Florida.
