to that of certain of the clay beds of Middlesex County, N. J., which 
are well known to belong to the Cretaceous Epoch. In the absence of 
sufficient fossil evidence, we cannot state, with absolute certainty, that 
the two deposits are equivalent, but there is little doubt that this 
will ultimately be proved, and that the New Jersey and Staten Island 
clays, ‘‘kaolins,” sandstone, lignite, etc., find another and their 
most northern outcrop on the north shore of Long Island. The 
speaker had already traced them as far as the Narrows, and intends 
continuing the investigation. 
DISCUSSION. 
Prof. D. S. MARTIN suggested that a map of these outcrops, drawn 
to scale, might throw light on the exact position of the Glen Cove 
specimens. They were remarkably like the Triassic rock, containing 
lignite stems, found in New Jersey, and may be drift material brought 
over from some such outcrop in that State. 
Dr. BRITTON replied that the same specimen contained angiosper- 
mous leaves, and that no boulders of diabase were noticed at Glen 
Cove. 
The PRESIDENT thought that more material was yet needed to 
render the determination of age absolutely sure. He had already ex- 
hibited similar specimens from Williamsburg, Lloyd’s Neck, and Glen 
Cove, which enclosed large numbers of angiospermous leaves. These 
resemble those of the Raritan clays, but a further collection was 
needed to identify them, though such a result was probable. The 
association of clays with the sandstones at Glen Cove seems to prove 
the strata to be essentially like those at the mouth of the Raritan. 
He further reported on some of the more interesting papers read at 
the recent meeting of the National Academy of Sciences. 
The Academy then adjourned for two weeks, to December 3, 
on account of the Centennial Celebration, on November 27, of 
the Evacuation of New York City, in 1783.
