5. _Beaverdam, Erie County._—In 1828 (Amer. Jour. Sci., vol. XIV, p. 31), Mr. Jeremiah Van Rensselaer described a tooth which must have been that of _Elephas primigenius_. It had been found near Lake Erie, at a place called Beaverdam, near a small rivulet, and at a height of 600 feet above the lake. He stated that there were 13 layers of enamel in a line 4.5 inches long. The tooth was sent to the Lyceum of Natural History, New York, but was probably destroyed in a fire at the old American Museum of Natural History. OHIO. (Maps 11, 36.) 1. _Waverly, Pike County._—In the U. S. National Museum is an upper molar of an elephant said to have been found in a gravel-pit of the Norfolk and Western Railroad, at Waverly. It was sent to the Smithsonian Institution in 1900 by Mr. E. Sehon, who stated that the tooth had been picked up along the railroad mentioned, about 30 miles south of Kenova, West Virginia, but that the gravel had been loaded on the cars at Waverly. The tooth is believed to be the hindermost milk molar. There are 10 plates in a line 100 mm. long. The Pleistocene geological conditions at Waverly may to some extent be learned by consulting Leverett’s paper forming Monograph XLI of the U. S. Geological Survey, pages 101–104. There is a possibility that this tooth was buried in gravels older than the last glacial stage. 2. _Zanesville, Muskingum County._—In 1853 (Amer. Jour. Sci., ser. 2, vol. XV, pp. 146–147) is found a brief account of the discovery of elephant remains at Zanesville. One tusk and four molars were found. Two of the latter weighed (probably while wet) 20 pounds each and two others 14 pounds each. They had been found on the line of what was then called the Ohio Central Railroad and in the eastern part of the city. At about the same time (Proc. Boston Soc. Nat. Hist., vol. IV, p. 377) Warren exhibited a tooth of an elephant, one of three received by him from Zanesville (misprinted Lanesville). In the second edition of his monograph on “Mastodon giganteus” Warren figured one of these teeth (his plate XXVIII). It was stated that he had four of the teeth, all belonging to _Elephas primigenius_. These are now in the American Museum of Natural History, New York. The right upper hindermost molar is a fine large tooth. The large front root is missing, as are quite certainly about 3 plates. There are now 28 present. The length along the nearly straight base is 335 mm. The rear is high and arched. There are 9 plates in a 100–mm. line and the enamel is little festooned. Foster, in 1857 (Proc. Amer. Assoc. Adv. Sci., 10th meeting, p. 156), described the discovery and exhumation of these remains, publishing a geological section illustrated by a figure. The elephant bed is 37 feet above the river and over 20 feet from the surface. In the collection of the State University at Columbus (No. 5296) is a fine upper hindermost molar of _Elephas primigenius_ credited to T. W.
