The section of the basement of the new building in which the alco- 
holic 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 
museum 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 Mr. Alfred C. Harrison, Jr., 
and Dr. H. M. Hiller. Mr. Rehn, besides assisting in various depart- 
ments, has arranged and catalogued the Rhoads collection of mammals, 
bringing 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 
dining the year, and Miss Wardle has made considerable advance 
in the cataloguing and arranging of the arch geological 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 
Museum. 
Most notable 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 scries of fossil mollusks 
from Florida.
