REPORT OF THE CORRESPONDING SECRETARY. 
Continuing the inquiries begun last year concerning Correspondents 
whom the postal authorities reported as removed from the recorded 
addresses, the whereabouts of several have been ascertained during the 
year. In many cases the reported decease of Correspondents has 
been authenticated. The assistance of the many persons who furn- 
ished biographical and other data in connection with this work is grate- 
fully acknowledged, and especial mention should be made of the War 
and Navy Departments. 
During the year the deaths have been regretfully announced of 
Augustus Radcliffe Grote, the American entomologist, who had resided 
for many years in Germany; Carl Gegenbaur, the eminent compara- 
tive anatomist, and Julius Victor Cams, the zoologist and bibliographer, 
Correspondents of the Academy. 
On the other hand, the luster of our rolls has been increased bv the 
addition of the names of Theodor Boveri, William Morton Wheeler, 
Nestor Grchant, Eduard Strasburger and Hugo de Vries, who have been 
awarded the Academy’s diploma in recognition of their distinguished 
services in the field of scientific research.
