In addition to cash in the treasury and the aggregate of sub¬ 
scriptions not paid, Dec. 12, there is required to inclose the 
building with its roof $51,336 25, or in round numbers 
$52,000 more than the amount now available, according to the 
treasurer’s statement. 
The aggregate of contracts for the building since its com¬ 
mencement is $55,710 52. Of this sum there remains unpaid, 
say $18,000. This balance will be settled in the course of a 
few weeks, when the existing contracts have been completed. 
Having briefly stated the condition of the work entrusted 
to this Board, as well as the state of the treasury of the build¬ 
ing fund, this report might here end. But it seems expedient 
to refer in a summary way to what remains yet to be done. 
That this may be generally understood, a description of the 
plan of the edifice to be built is presented. 
The north wing of the new Academy of Natural Sciences of 
Philadelphia, at the southwest corner of Nineteenth and Race 
Streets, covers an area of 186 by 75 feet. It will have an ele¬ 
vation of fi5 feet from the pavement to the cornice. It is in 
the collegiate Gothic style of architecture, and the exterior 
walls*are faced with green serpentine from Brinton’s quarries, 
and the openings are trimmed with drab-colored Ohio sand¬ 
stone. The roof of slate, in the Mansard style, is crowned with 
a skylight. 
The architectural appearance of the building when finished, 
will be, it is believed, as handsome as any other of its size in 
our city. It is fire-proof in construction, and will be thoroughly 
lighted, warmed, and ventilated. 
At the eastern end of the cellar are two rooms, designed for 
the use of taxidermists, each 19 by 24 feet, one of which com¬ 
municates with the museum above^by a lift or dumb waiter of 
ample dimensions; and also two rooms, each 18 by 22 feet, for 
printing materials and presses. 
On the eastern extremity of the first floor is provided a 
reading-room, curators’ office, publication office, artists’ room, 
wash-room and water-closets, and librarian’s office, which con¬ 
nects with a fire-proof, the entrance hall and the library. Above
