porated in the permanent collection, and at the time of the 
writing of my last report this was essentially accomplished. 
During the present year attention has been given to the 
mounting of the miscellaneous accumulation of phanerogamic 
material, thus bringing into use the entire research collections 
of the institution. This task has been accomplished, with the 
exception of a few securely boxed portions of recently ac- 
quired herbaria, which we hope to mount during the early 
part of next year. 
Specimens at all liable to insect depredation have been 
thoroughly poisoned with mercuric bichloride, both to insure 
their permanent preservation, and to avoid the necessity of 
frequent and undesirable fumigation in the future. 
(a) Flat or pressed specimens. A total of 82,916 herbarium 
sheets, representing at least 95,000 specimens, have been 
incorporated. 
(6) Bulky specimens. Fully 5,800 specimens of dimen- 
sions prohibiting their being mounted on herbarium sheets, 
consisting mainly of fungi and lichens, stems of tree-ferns, 
and fruits and seeds of flowering plants, have been placed in 
multiple paper boxes of the following sizes:

3. ARRANGEMENT OF THE HERBARIA. The general dis- 
position of the collections has not been altered during the 
year, but numerous minor changes have to be made from 
time to time to accommodate the unequal growth of the sev- 
eral divisions. 
(2) Garden herbarium. An aggregate of 58,055 speci- 
mens was received. From these and from previously acquired 
material about 94,000 specimens, mounted on 74,916 sheets, 
were incorporated.
