A BRYOLOGICAL MEMORIAL MEETING. 
CoLumBus, Ohio, was the home for many years of William S. Sullivant and 
Leo Lesquereux, two names which will always awaken love and reverence from 
all students of North American mosses and hepatics. It is twenty-six years 
since Sullivant died, and this last quarter of the century has seen a marked 
extension of the limits of bryological study and a large increase in the num- 
ber of students. It seems a fitting time and place to take a survey of the 
field, review the past and make plans for the future; hence it is proposed to 
make the coming meeting of the American Association for the Advancement — 
of Science, which is to be held at Columbus, August 21-26, the occasion fora 
Memorial Day in honor of the Nestors in American bryology. It is pro- 
posed to present a series of historical papers, illustrated by photographs, 
‘Specimens, microscopical exhibits, and literature showing the bryological 
work of Hedwig, Palisot de Beauvois, Michaux, Muhlenberg, Bridel, Torrey, 
Drummond, Hooker and Wilson, Greville, Sullivant and Lesquereux, James 
and Watson, ‘Austin, Ravenel, Wolle, Faxon and Eaton. Supplement- 
ing these there will be shown collections of specimens, macroscopic and 
microscopic, illustrating the monographic work of recent American students. 
If foreign students who have worked on North American bryophytes can be 
persuaded to cooperate with us, the following will be asked to contribute: 
Bescherelle, Brotherus, Cardot, Dixon, Kindberg, Mitten, Pearson, Roll, 
Stephani, and Warnstorf. An effort will be made to secure the loan of type 
specimens and illustrations from the following sources : Academy of Natural 
Sciences of Philadelphia, Academy of Sciences of New York, Columbia var 
versity, Geological and Natural History Survey of Canada, Harvard Univer- 
sity, National Museum, Ohio State University, University of Wisconsin, as
