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. Brixton 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.
