REPORT OF THE CORRESPONDING SECRETARY. 
The deaths of correspondents reported during the year were 
as follows: Joel A. Aden, Wm. A. Buckhout, and Charles B. Cory. 
No correspondents were elected. 
As indicating the renewal of the international exchange of 
amenities between scientific and educational institutions an in- 
creased number of invitations was received. Among the more 
important of these events were the fifty-year jubilee of the Geol- 
ogical Society of Stockholm the twenty-fifth annual meeting of 
the American Academy of Political and Social Science, to which 
the President appointed Dr. Macfarlane, Dr. Stone, and the cor- 
responding secretary as delegates; the centenary celebration of 
the founding of the Philadelphia College of Pharmacy and Science 
to which Mr. Rehn was made a delegate; the Second International 
Congress of Eugenics at which the Academy was represented by 
Professors Conklin and McClung; the inauguration of Dr. J. M. 
Thomas as President of Pennsylvania State College; the semicente- 
nary of the Society for the Study of the Fauna and Flora of Finland ; 
the seven-hundreth anniversary of the founding of the University of 
Padova; the postponed International Geological Congress to be held 
in Brussels; and the organization under the auspices of the Nation- 
al Research Council of an Institute for Research in Tropical Amer- 
ica to which Dr. Stone was delegated to represent the Academy. 
To those gatherings at which representation of the Academy was 
impractical letters of felicitation or addresses were sent. 
From the American Ornithologists’ Union was received a resolu- 
tion thanking the Academy for courtesies extended during its thirty- 
fifth stated meeting.
