BOTANICAL SUPPLIES 
The Marine Biological Laboratory Supply Department is prepared to 
supply schools and colleges with class material as well as museum specimens. 
The following material can now be supplied, as well as some others, on 
request : 
Marine Algae preserved or mounted. Besides the usual forms studied a 
large number can be supplied either fresh, in season; or preserved. A great 
variety of Fungi can be furnished ; special stress is laid on those of economic 
importance. Moss, Fern and Seed- Plant Material supplied as demanded. 
A large number of Pure Cultures of Fungi are on hand and more are con- 
stantly being added. 
During the months of October to May, inclusive, the Department will 
make shipments of live Fucus for fertilization studies. By packing according 
to a special method the material can be shipped for a long distance, and yet 
be in good condition on reaching the consignee. 
The Department now has a trained botanist on its staff throughout the 
year, and consequently requests for material not listed, can be given attention 
in a way that has hitherto been impossible. 
Zoological and Embryological supplies furnished. Catalogs and other in- 
formation sent on request. Address all communications to
