, and others report the eruption of teeth in the newborn. In Dumas' case the teeth had to be extracted on account of ulceration of the tongue. Instances of triple dentition late in life are quite numerous, many occurring after a hundred years. Mentzelius speaks of a man of one hundred and ten who had nine new teeth. Lord Bacon cites the case of a Countess Desmond, who when over a century old had two new teeth; Hufeland saw an instance of dentition at one hundred and sixteen; Nitzsch speaks of one at one hundred, and the Ephemerides contain an account of a triple dentition at one hundred and twenty. There is an account of a country laborer who lost all his teeth by the time he arrived at his sixtieth year of age, but about a half year afterward a new set made their appearance. Bisset mentions an account of an old woman who acquired twelve molar teeth at the age of ninety-eight. Carre notes a case of dental eruption in an individual of eighty-five. Mazzoti speaks of a third dentition, and Ysabeau writes of dentition of a molar at the age of ninety-two. There is a record of a physician of the name of Slave who retained all his second teeth until the age of eighty, when they fell out; after five years another set appeared, which he retained until his death at one hundred. In the same report there is mentioned an old Scotchman who died at one hundred and ten, whose teeth were renewed at an advanced age after he had lost his second teeth. One of the older journals speaks of dentition at seventy, eighty-four, ninety, and one hundred and fourteen. The Philosophical Transactions of London contain accounts of dentition at seventy-five and eighty-one. Bassett tells of an old woman who had twelve molar teeth at the age of eighty-eight. In France there is recorded dentition at eighty-five and an account of an old man of seventy-three who had six new teeth. Von Helmont relates an instance of triple dentition at the same age. There is recorded in Germany an account of a woman of ninety who had dentition at forty-seven and sixty-seven, each time a new set of teeth appearing; Hunter and Petrequin have observed similar cases. Carter describes an example of third dentition. Lison makes a curious observation of a sixth dentition. Edentulousness.--We have already noticed the association of congenital alopecia with edentulousness, but, strange to say, Magitot has remarked that "l'homme-chien," was the subject of defective dentition.
