I. Economic Musgum. Specimens were added to all the 
exhibits of this museum, but the general plan of arrangement 
was unchanged except in the west wing, where the sixteen 
new exhibition cases were installed. The increase of the 
collections in the west wing necessitated their complete re- 
arrangement. 
II. Sysrematic Museum. The three elements comprising 
the systematic museum, namely, the Synoptic Collection, 
the Microscope Exhibit and the Local Flora, were increased 
by the addition of specimens or improved by the replacing of 
old specimens. No general rearrangement was necessary. 
III. Fosstr PLant Museum. About the end of the year 
six additional table cases for fossil plants were placed in the 
west hall of the basement. The whole exhibition space of 
the basement is now’ devoted to the fossil plant museum. 
The transfer of specimens, previously held in storage, to 
the new cases has been begun. The collections have been 
increased by a large number of specimens from the Creta- 
ceous deposits at Kreischerville, Staten Island, New York, 
from the Grand Gulf formation of Alabama and from several 
of the South Atlantic states. 
IV. Lasetinc. All new specimens added to the public 
exhibits of the several museums were furnished with printed 
labels. Several hundred labels printed during earlier years 
were rewritten and printed anew in order to have them con- 
form to improved styles adopted later. 
Herbarium 
I. MounTiInc AND CONSERVING OF SPECIMENS. About 
49,000 specimens, selected from those received during the 
year, and previous years, were incorporated in the perma- 
nent collections. The specimens fall into two groups: 
(a) Flat or pressed specimens. About 47,000 specimens 
were poisoned and mounted on 36,184 sheets of herbarium 
paper, and distributed in the cases. 
(6) Bulky specimens. About 2,000 specimens of fruits, 
seeds, stems and other parts of plants too thick to mount on 
sheets were placed in boxes and distributed in the cases.
