Creator	Hitchcock, Edward, 1793-1864
Title	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
Date Issued	1861
Abstract	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.
