ABBOTT, Charles Conrad, naturalist, born in Trenton, New Jersey, 4 June, 1843. He was educated at Trenton academy, and studied medicine at the University of Pennsylvania, graduating in 1865. Dr. Abbott has very carefully investigated the first appearance of prehistoric man in this country, and has accumulated a valuable archaeological collection containing 20,000 specimens, mainly stone implements, which is now in the Peabody museum, Cambridge, Massachusetts. He is a frequent contributor to the scientific journals, and has also written reports for the government surveys. He is also the author of "Primitive Industry: or, Illustrations of the Handwork in Stone, Bone, and Clay of the Native Races of the Northern Atlantic Seaboard of America" (Salem, 1881). His "Rambles of a Naturalist" (New York, 1884) and "Upland and Meadow" (1886) are interesting descriptions of his personal experiences in New Jersey.
