Association of American Geologists and Naturalists

Two pages from "Abstract of the proceedings of the fourth session of the Association of American Geologists and Naturalists" extracted from volume 45, number 2 of the American Journal of Science and Arts, published in 1843. The extract describes a debate between Edward Hitchcock, Joseph Nicollete, William C. Redfield, and Henry Darwin Rogers regarding Louis Agassiz's glacial theory. Hitchcock notes that he is almost afraid to say anything more on the subject due to much misunderstanding of his previous reports on it, but states that he believes the phenomena of drift is the result of ice and water, though he is uncertain which is a greater force or what causes such action of ice and water.

On a new fossil fish and new fossil footmarks

Hitchcock, Edward, 1793-1864

An article by Edward Hitchcock extracted from the American Journal of Science and Arts second series, volume 21, number 61, published in 1856. The article describes two fossil specimens and includes an illustration. First, Hitchcock describes a fish fossil specimen, where it was found, and Professor Louis Agassiz's views about the specimen. He then provides a detailed description of fossil footprints discovered in sandstone in Turner's Falls, Massachusetts including the scientific name he has given the specimen (Gigandipus caudalus) and a description of the slab in which the prints are embedded. He posits that the tracks were not made by a bird due to the presence of a tail.

On the conversion of certain conglomerates into talcose and micaceous schists and gneiss, by the elongation, flattening and metamorphosis of the pebbles and the cement

Hitchcock, Edward, 1793-1864

An illustrated article by Edward Hitchcock extracted from volume 31, number 93 of the second series of the American Journal of Science and Arts, published in 1861, in which Edward Hitchcock discusses pebbles found in Vermont and Newport, Rhode Island. Hitchcock explains his and his son Charles H. Hitchcock's observations of these pebbles and why he believes they prove the theory of metamorphism. He notes that they have been elongated, flattened, and occasionally have formed around each other, undergoing changes that would not be possible for solid rock. He ends with a note about some arguments against his theory, and reiterates why he believes these pebbles are the result of metamorphism.
