development of the gametophyte, fertilization, and embryogeny. 
BRUCHMANN’S success stimulated others, and while no one else found 
any prothallia of European species, SPESSARD found American species, 
Hottoway found prothallia of New Zealand species, while both Hotto- 
way and Lawson discovered the prothallia of Tmesipteris and Psilotum. 
BRUCHMANN naturally became interested in other subterranean 
prothallia, and succeeded in finding prothallia of Ophioglossum vulgatum 
and Botrychium Lunaria, both of which he described in his usual thorough 
manner. Selaginella, since it is a lycopod, was investigated, although its 
prothallia are not subterranean. He also made a study of the behavior 
of the sperms of lycopods with special reference to chemotaxis. 
The paper of 1898 brought widespread recognition, for in 1899 he 
received the Plato Medal of the Academy of Science of Munich, and in 
the following year the Demaziéres Prize of the Paris Academy of Sci- 
ences, which carries with it a monetary consideration of 1500 francs. 
Still later he was made an honorary member of the Naturforschende 
Gesellschaft of Berne. In a letter received by the writer in 1911, how- 
ever, BRUCHMANN states that, while the prizes are gratifying, his greatest 
satisfaction is in the recognition his work is receiving in textbooks which 
bring his results before students in the schools. His experience as a 
teacher prompted him to prepare splendid sets of prothallia for labora- 
tory demonstration, and these are now used in most German universities 
and in many universities of other countries. 
BRUCHMANN’s life and patient, persistent work prove that one who 
has the interest and will to do research work can achieve a high rank 
in science without the stimulus of a great university—CHARLEs J. 
CHAMBERLAIN, University of Chicago.
