This Memoir is a continuation of the work upon the Cubomeduse 
which was begun by the late Dr. FRANKLIN Srory Conant, and it 
contains his notes of physiological experiments, as well as new results 
which have been obtained by Dr. E. W. Bercrer from the study of 
material which had been collected by Dr. Conant, who had hoped to 
make it the object of further study. 
In order that this work may be made public as a continuation of 
Dr. Conant’s researches, his sister, GRACE WILBUR CoNANT, has, with the 
cooperation of other members of his family, made an adequate and 
generous provision for its publication. 
For this gift, which is at once a contribution to science and a 
memorial of an able and promising investigator, lately student and 
fellow in this institution, the Johns Hopkins University returns its 
grateful acknowledgments. 
DANIEL C. GILMAN, President. 
W. K. BROOKS, Professor of Zoology.
