The first notice of this jaw appears to have been given in 1838 (First Ann. Rep. Geol. Surv. Ohio, pp. 96, 97) by C. Briggs, assistant geologist of the survey. He stated that with some other bones it had been found, by unnamed persons, about 1835, in the bank of a branch of Salt Creek, in the northwest part of the county. A second search, made by Briggs and Foster, brought to light fragments of the skull, two teeth, and some other parts of the skeleton. Parts of the tusk in a frail condition were secured. It is interesting to learn that the tusk measured on the outer curve 10 feet 9 inches. The writer has been unable to learn what has become of these bones; none is in the collection of the State University at Columbus. The report made by Briggs on this specimen was reprinted in the American Journal of Science, volume XXXIV, 1838, page 358, in a review of Mathers’ First Annual Report. The author of the review was almost certainly J. W. Foster. An unsigned letter, apparently also by Foster, follows, in which are poor figures of the jaw and one of the teeth. In this letter the name _Elephas jacksoni_ is applied to the remains. In 1839 (Amer. Jour. Sci., vol. XXXVI, p. 190), Foster contributed a figure of one of the teeth, probably a hindermost molar, but it is uncertain whether it represents the whole tooth or the remaining part of a worn one; nor is the amount of reduction indicated. The present writer finds it impossible to decide whether the tooth belongs to _Elephas primigenius_ or _E. columbi_. 2. _Beverly, Washington County._—In 1874 (Geol. Surv. Ohio, vol. II, pt. 1, p. 471), Mr. E. B. Andrews reported that, several years before he wrote, parts of the skeleton of a huge mammoth had been dug up in Beverly. Among other parts were several large teeth in good preservation, one of which was deposited in the cabinet of Marietta College; but the writer has not been able to learn anything about it. A Dr. Bowen, of Waterford Township, was said to have found, somewhere farther up Muskingum River, a shoulder-blade of a mammoth; but this locality must have been in Morgan County. The identification of the species is also questionable. 3. _Nashport, Muskingum County._—J. W. Foster (Geol. Surv. Ohio, vol. II, 1838, p. 80) reported a molar and a tusk of an elephant had been dug up at Nashport, in excavating a canal. With these had been found remains of a mastodon, of _Castoroides_, and of a supposed sheep. More probably the latter was an intrusion of a domestic sheep. These remains had been preserved in the Zanesville Athenæum, but the writer can get no trace of them.
