lection from Trenton. Both these collections are in the Archaeological Museum in Cambridge, Mass., where these specimens can at any time be seen. No. 19723 is specially interesting, because Professor Putnam took it with his own hands out of Trenton gravel from behind a small boulder which was firmly embedded four feet below the surface of the soil (see Proceedings of the Boston Society of Natural History, Vol. xxi. p. 149).

For the sake of those who are not perfectly familiar with the order of the geologic formations, a table is here inserted.
