See Mr Home's Observations on the Teeth of Graminivorous Animals, Phil. Trans. 1799. Also, an Essay on the Structure of the Teeth, by Dr Blake.

[223] In a paper inserted in the fourth volume of the American Philosophical Transactions, an account is given of two different grinders that are found at the Salt Licks near the Ohio. One of them resembles the grinder of the elephant, and may have belonged to the Elephas Americanus of Cuvier; the other agrees pretty nearly with the grinder of Dr Hunter's animal incognitum. The author of the paper thinks that the animal incognitum was not wholly carnivorous, as the incisores, or canine teeth, are never found. At the Great Bone Lick, bones of smaller animals, particularly of the buffalo kind, have been discovered. The saline impregnation of the earth at these Licks must no doubt have contributed to the preservation of the bones. Trans. American Phil. Soc. vol. iv. (1799,) p. 510, &c.
