The Third Edition of the Geology of the City of New York is much enlarged over the Second: first, through the necessary additions of further geological studies of Manhattan Island by various investigators, and second, through the desirable extension of the geology of Brooklyn Borough, which is made the justification of epitomizing the geology of Long Island. The mineralogical detail has been more fully given, and, in a few expository sections, brief outlines of the Second Edition have undergone apposite elaboration. The author acknowledges the courteous assistance of the United States Geological Survey, by valuable loans of original drawings; that of the State Geologist of New York, through his permission to copy an outline map of a hypothetical glacial condition on Long Island, presented by Professor J. B. Woodworth; and that of Dr. Wallace G. Levison, in the use of plates to illustrate his unique find of Chrysoberyl on Manhattan Island.
