[M. Roche Lubin, Rodez (Aveyron). An incisor tooth extracted from the palate of an ox.

On the 14th of April 1837, I was requested by M. Bonhome, near Rhodez, to extract a tooth growing in the middle of the palate of his young bull. The curiosity of the thing made me

hasten to comply with his request. The animal being conveniently secured, I removed the tooth in the usual way. A very considerable hemorrhage followed the extraction of it, which was performed with some difficulty, on account of the tooth being firmly implanted in the palatine arch. It was situated at the middle of the mesian line, between the fifth alveola on the right side and the corresponding one on the left. It was precisely of the same character with the usual incisor tooth of the ox.

This is, I believe, the only fact of the kind on record, the incisor teeth being wanting in the upper jaw of cattle.
