of students in the report of the Assistant Director, hereto ap- 
ended. The provision for members of the staff to visit other 
institutions has again proved most valuable, the most note- 
worthy event of the past year being a study by Dr. Marshall 
A. Howe, Assistant Curator, of the collections of algae in 
European museums, an account of which has already been 
published by him in our JouRNAL. 
Research Scholarships 
Research Scholarships have been granted to three persons 
for a total of ten months, in accordance with the action of the 
Board of Managers at the annual meeting in January, 1903. 
Dr. J. C. Arthur, Botanist to the Agricultural Experiment 
Station and Professor of Plant Physiology and Pathology, 
Purdue University, held a scholarship for a month, during 
which time he made some critical studies of the Uredinae 
(rusts) for the purpose of completing his investigations of the 
polymorphism of these interesting parasites which spend por- 
tions of their life-cycle on different species of plants. Dr. 
Arthur’s studies are also to be used in the description of the 
group in the North American Flora. He has contributed 
many specimens of these fungi to our collections. 
Dr. J. E. Kirkwood, Assistant Professor of Botany in 
Syracuse University, held a research scholarship for two 
months, during which period some further studies on the em- 
bryology of the Cucurbitaceae were pushed to an advanced 
stage of completion and some bibliographical work on the 
subject was accomplished. 
Mr. C. B. Robinson, who held a scholarship for one period 
of four months and a second period of three months, engaged 
in the study, installation and arrangement of the collections 
from the Philippines, and in the preparation of a monograph 
of the stone-worts (Characeae), made possible by the great 
collection of these plants presented to the Garden some years 
ago by Dr. T. F. Allen.
