2. Bluelick Springs, Nicholas County.—In the collection made by Mr. Thomas W. Hunter, in the sulphur spring at the place mentioned, the writer has seen two ungual phalanges which were identified as those of Megalonyx jeffersonii.
3. Henderson, Henderson County.—A considerable part of a skeleton of Megalonyx jeffersonii was found at different times extending through some years, about 5 or 6 miles below Henderson, in the bank of Ohio River. This skeleton is now in the University of Indiana and was described by Leidy in 1855 (Smithson. Contrib. Knowl., vol. VII, art. 3). This collection furnished a fine skull and lower jaw. In the same deposits were found many horns and bones of deer. The geology of the locality and the age of the bones will be discussed on page [405].
FINDS OF PLEISTOCENE MASTODONS IN EASTERN NORTH AMERICA.

1. Essex County.—In 1898 (Science, n. s., vol. VII, p. 80), Dr. H. M. Ami reported that he had exhumed some mastodon remains in this county. The exact locality was not given. It was north of the west end of Lake Erie. The section dug up was from 6 to 8 feet deep. At the bottom were clay and boulders; above this were found gravel and the bones, and above these sand, shell marl, peat, and other sands of various colors. The remains were fragmentary.
2. Morpeth and Highgate, Elgin County.—In 1858 (Canad. Jour. Indust. Sci. Art, ser. 2, vol. III, p. 356), E. J. Chapman announced the discovery of a tooth of mastodon at or near this place. He had seen a drawing of the tooth. It appears that another man also had sent to the journal an account of the discovery, accompanied by drawings. These showed 5 distinct crown-ridges.
In 1891 (Geol. Mag. London, ser. 3, vol. VIII, p. 504; Brit. Assoc. Adv. Sci., 64th meeting, 1892, p. 654), Professor J. Hoyes Panton gave an account of the discovery of mammoth and mastodon bones at Highgate, only a few miles north of Morpeth. These were found in a bed of marl. Some measurements of the mastodon were given.
3. St. Thomas, Elgin County.—In a private museum at Niagara Falls, owned at the time by Davis Brothers, the writer saw a quite complete lower jaw and a tusk, labeled as having been found at this place in 1856, on the farm of Isaac Barnard. The jaw had the last 3 teeth on the right side and the last 2 on the left side. In front was a tusk about 6 inches long which appeared to be in the middle of the jaw. The upper tusk is curved in a semicircle. Dr. J. W. Dawson (Geol. Mag. London, ser. 1, vol. VI, 1869, p. 39) mentions this find. He stated that there were 2 lower tusks. If this was the case the species M. progenium is indicated.
4. London, Middlesex County.—In the article quoted above from the Geological Magazine of London, Dr. J. W. Dawson stated that there were in the Provincial Museum 3 mastodon molars which had been found at London.
