Mr. Arthur Hollick presented a piece of ferruginous sandstone, con- 
taining impressions of dicotyledonous leaves. The specimen resembles 
those found in the Drift, at Tottenville and Princes Bay, which are 
known to be derived from the Cretaceous clays. The specimen in 
question, however, was found as a Drift rock on the Serpentine hills, 
to the north of the Cretaceous area. It is possible that it may have 
been brought to the place where it was found by human agency, but 
if not, its occurrence there is more or less of a problem which future 
discoveries may solve. It is desired, at present, merely to place the 
fact upon record.

emy of Natural Sciences of Philadelphia, it was announced that the 
result of the balloting among the members of the club upon the ques- 
tion of active co-operation in the proposed new expedition to the Arctic 
regions under the lead of Lieut. R. E. Peary, stood in favor of the 
project.
