REPORT OF THE CURATOR OF THE MUSEUMS 
AND HERBARIUM. 
Dr. N. L. Britton, DrrEcTOR-IN-CHIEF. 
Str: I have the honor to submit herewith my report as 
Curator of the Museums and Herbarium, for the year 1903: 
The development of the collections and exhibits has been 
continued on the general plans outlined in my previous re- 
ports. 
I. Genera Accessions. The several collections were 
increased by an aggregate of 85,750 specimens. From this 
aggregate, and from the store of previously acquired mate- 
rial, about 45,000 specimens of plants and plant-products 
have been incorporated in the permanent exhibits and study 
collections. From the same sources the duplicate collections 
were replenished. The specimens were obtained as follows: 
(2) Gifts and purchases. A total of 31,878 specimens was 
thus added to the collections. This large increase to the re- 
sources of the institution came, not only through the direct 
gifts of specimens by members and friends of the Garden, 
but also by the gifts of money for the purchase of desirable 
specimens, in addition to the annual appropriation for the 
same purpose. 
(6) Exchanges. The surplus museum and herbarium ma- 
terial comprising the duplicate collections, which were much 
depleted last year, were replenished during the early part of 
this year and again drawn on for exchange purposes. 
Through this source 19,407 specimens were obtained. 
In addition to numerous individuals, exchange relations 
were established with the following institutions, thus increas- 
ing our exchange list to a total of fifty-nine: 
Botanical Garden, Buitenzorg, Java. 
Botanical Garden, Peradeniya, Ceylon. 
Forest School, Yale University. 
Royal University, Modena, Italy. 
Public Gardens and Plantations, Jamaica. 
California Academy of Sciences.
