a commanding hallway which leads directly to the main Museum 
building, through the space formerly occupied by the old Lecture 
Hall. 
I he stairways in the main Museum building have been removed 
to the Nineteenth street entrance, from which a new vestibule has 
been constructed, shut off from the galleries of each floor by fire-walls 
and automatic fire-doors. 
On the lot situated at Nineteenth and Cherry streets, 50 x 130 feet 
in size, has been erected a handsome fireproof building, now occupied 
by the Hall of the Academy, the Library stack and Reading Room. 
The third floor, with the top floor of the main Museum building,

All are reached by an electric elevator. 
In the old Museum all the iron columns have been fireproofed and

becoming badly weathered, with brick and terra cotta, and to add 
such terra cotta facings to the middle wing as will make the entire 
building uniform in appearance. 
The Museum, which had been closed to the public during the altera- 
tions, was reopened early in the year, and much of the time of the 
Museum staff has been devoted to the cleansing and rearrangement 
of the specimens. 
A radical rearrangement has been effected on the mammal floor 
and many of the osteological specimens temporarily removed from 
exhibition. 
All the water birds were removed while the cases were being cleansed 
and repainted and were then rearranged. 
The immense series of jars containing the alcoholic collections have 
been thoroughly cleansed before being arranged in the new vaults. 
Notwithstanding this unusual amount of routine work, considerable 
local field work was done by members of the Museum staff and several
