PROCEEDINGS OF THE ACADEMY OF 
[Dec., 
Henry Skinner, Professor Philip P. Calvert, and Dr. W. J. Holland 
were appointed delegates; the International Forestry Congress; 
the dedication exercises of the New York State Education Build¬ 
ing, at which Professor Henry F. Osborn represented the Academy; 
the XYIth International Congress of Orientalists; the one-hundred 
and twenty-fifth anniversary of the founding of the University 
of Pittsburgh, at which Mr. George II. Clapp served as a delegate, 
and the inauguration exercises of The William H. Rice Institute, 
on which occasion Professor Allen J. Smith and Professor Hugo 
de Vries were the Academy’s delegates. Formal addresses or simpler 
letters of congratulation were forwarded to the executive officers 
of all of the events named. 
The year 1912 will be remembered as one especially noteworthy 
in the history of the Academy, because it marked the completion 
of the first century of the Academy’s corporate existence. In 
connection with the celebration of this event the volume of corre¬ 
spondence was much augmented, especially by that conducted on 
behalf of the Sub-Committee on Invitations, upon which the 
Corresponding Secretary served. 
During the month of January the invitation prepared at the 
close of the last fiscal year was mailed, along with a provisional 
program and a card requesting replies, to 780 learned societies and 
institutions in all parts of the world and to the full list of corre¬ 
spondents whose addresses have been verified. The reponses were 
most gratifying, both in number and character. They began to 
arrive almost immediately, came in increasing volume until the 
opening of the celebration, and continued to be received during 
and even after that event. In all four hundred and five institutions 
responded, of which three hundred and twenty-five sent congratu¬ 
latory addresses, letters or telegrams, many of which were very 
gracefully expressed and handsomely executed. A full list of these 
is given and many of the letters are quoted in full in the memo¬ 
rial volume now before the meeting. A selection of some of the 
more interesting or beautiful ones is on exhibition in the reading 
room. One hundred and forty-seven institutions appointed one 
hundred and ninety-four delegates. Excluding duplications, one 
hundred and fifty-seven persons were appointed, of which one 
hundred and twelve are known to have been in attendance. Of 
the correspondents fifty-two sent letters of congratulation and 
a number regrets, and thirteen were present at the meetings. 
Finally, after letters had ceased to be received, an acknowledgment
