Str: I have the honor to submit herewith my report as 
Head Curator of the Museums and Herbarium for the year

Accessions 
Specimens from nearly all parts of the world were received 
for the Museums and Herbarium. They were secured as 
follows : 
(2) Gifts and purchases. A total of 54,140 specimens, 
consisting largely of miscellaneous plants from the Philip- 
pine Islands, western North America and tropical America, 
and the hepatics and mosses comprising the herbarium of the 
late Mr. Wm. Mitten, were brought together by these means. 
(6) Exchanges. Exchanges with other institutions and 
with individuals added a total of 10,499 specimens to the 
collections. The greater part of these specimens are from 
North America, Europe and the Philippine Islands. 
(c) Exploration. The several exploring expeditions brought 
back an aggregate of 17,137 specimens, which consist chiefly 
of plants from Porto Rico, Costa Rica, Jamaica, Cuba, sub- 
tropical Florida and temperate North America. 
Collections were therefore increased by 81,776 specimens. 
Museums 
The utility of the collections comprising the public museums 
was increased by the addition of new specimens and the re- 
arrangement of old ones. All additions were permanently 
labeled as they were installed. The permanent museum 
equipment was enlarged by the addition of minor appliances, 
and the acquisition of specimen jars as follows:
