9 Objects made of chloromelanite have been picked up in thirty-eight of the departments of France. No deposit of it is known now.—Fischer and Damour: _Rev. Arch_., 1877. 10 Obsidian is chiefly found in the mines and quarries of Terro de las Navajas (Mexico), known in the time of the Aztecs. Deposits have also lately been discovered in Hungary and the island of Melos. 11 Calaïte differs from the turquoise by an equivalent of aluminium; it was described by M. Damour in 1864. It is said that traces of it have been found in the tin mines of Montebras, which appear to have been worked from prehistoric times.—_Mat_., 1881, p. 166, etc. Cartailhac: _Bul. Soc.

The Baumes-Chaudes caves are the most complete charnel houses of Neolithic times yet discovered. Dr. Prunières collected in them as many as three hundred skeletons. 15 “In a large proportion of the long barrows I have opened, the skulls exhumed have been found to be cleft apparently with a blunt weapon, such as a club or stone axe.”—_Archæologia_, vol. xlii., p. 161, etc. 16 Wilson: “Prehistoric Annals of Scotland,” 2d ed., vol. i., p. 187. 17 Keller: “Pfahlbauten,” _Siebenter Bericht, p_. 27, Zurich, 1876. 18 “Habitants Primitifs de la Scandinavie,” pp. 212 and 213. 19 “On the Occurrence of Fossil Bones in South America.” 20 _Journal Anthropological Society_, May, 1882. 21 Wyman: _Report Peabody Museum_, 1874, p, 40. 22 This skill was not always shown, for Dr. Topinard speaks of a femur found at Feigneux which had been so clumsily set that one part greatly overlapped the other.—Bul.
