would like to receive from American entomologists copies of their 
papers containing descriptions of new species of this group issued 
since the publication, in 1876, of Packard’s monograph of Ameri- 
can geometrids. 
— The lecture course of the New York Academy of Sciences 
opened on December 14th, by a lecture on the genealogy of the 
Mammalia by Professor E. D. Cope. The next lecture will be

PROCEEDINGS OF SCIENTIFIC SOCIETIES. 
THE INTERNATIONAL GEOLOGICAL CONGRESS, at Berlin, Sept. 
th to Oct. 3, 1885.—The third and most important session of 
the International Geological Congress, which was instituted by an 
American committee of the A. A. A. S., at its Buffalo meeting in 
1876, has just been held. 
The first session at Paris, in 1878, was really a pour parler 
which broke ground. The next session at Bologna, in 1881, 
accomplished something, but was especially useful in preparing 
for the work of the session just closed by deciding to produce a 
geological map of Europe on a scale of ysoo000, and entrusting 
its execution to one committee, while another was appointed to 
devise some scheme for unifying the nomenclature and, where 
possible, of fixing the limits of various congeries of beds which 
had heretofore been differently understood by different geologists. 
The obstacles which faced these committees will be at once under- 
stood from this bare statement and will modify any hasty impres- 
sion that, in fact, very little has been accomplished. | 
The two committees, or a majority of members of each, met at 
Foix, and at Zurich, during the four years which intervened be- 
tween the Congresses of Bologna and Berlin, and the action of 
the congress which has just ended was almost exclusively con- 
fined to the propositions made in the printed reports of these 
committees. ` 
Those who arrived in Berlin some days before the opening of 
the congress found, at the superb Bergakademie on the Invaliden
