25. _Jacksonburg, Wayne County._—Dr. John T. Plummer (Amer. Jour. Sci., ser. I, vol. XLIV, 1843, p. 302) stated that he had obtained near Jacksonburg, 18 miles west of Richmond, a tooth. It had four cross-ridges and was so well preserved that a dentist attempted to make artificial human teeth from it. According to Leverett’s map, the tooth was probably on the surface of Wisconsin drift. It could not, therefore, have lived until after the Shelbyville moraine had been cleared of ice.
26. _Richmond, Wayne County._—In the twelfth volume of the American Geologist, page 73, Professor Joseph Moore, then of Earlham College, stated that some sound teeth and decayed bones of a mastodon had been found 2 miles east of Richmond, in scooping out a fish-pond. A label on a lower last molar states that the remains were found on the Floyd farm. With them were found a fragment of an incisor of _Castoroides_. According to Leverett (Monogr. LIII, plate VI), the locality would be outside of the Bloomington moraine of the Wisconsin drift.

27. _Penn Township, Jay County._—Mr. David McCaslin (12th Ann. Rep. Geol. Surv. Indiana, p. 169) stated that various remains of mastodon had been found in Jay County. He mentioned in particular fragments found in Penn Township (township 24 north, range 8 east) and which seemed to indicate the presence of an entire skeleton. It is, however, possible that this skeleton was that of an elephant. The Salamonie moraine passes diagonally through this township.
28. _Fort Wayne, Allen County._—Richard Lydekker (Foss. Mamm. Brit. Mus., pt. IV, p. 17) stated that there is in the British Museum of Natural History a cast of the left half of the brain of an immature specimen of mastodon which had been found at Fort Wayne. The cast had been sent to that museum by the Chicago Academy of Science.
Professor C. R. Dryer (16th Ann. Rep. Geol. Surv. Indiana, p. 129) reported five skeletons of mastodons found in Allen County. No particulars were given. A note from Professor Dryer to the present writer states that he had been unable to obtain additional information. It is not unlikely that some of these remains belonged to elephants, but doubtless some were those of mastodons. It is to be regretted that so little of value is secured from such discoveries.
