tion, stone, or metallic implements. The cranial appearance of the 
skull is, however, truly remarkable, although it approaches very much 
to the configuration of the cranium from Montrose, to which I shall 
presently allude. It is brachycephalic, the occiput being high, and 
the supraorbital ridges well developed. The length from the glabella 
to the occiput is 6" 5"', the breadth across the parietal tubers 5" 5"'. 
Dr. Schauffhausen states : " Notwithstanding tlie great similarity in 
the form of the forehead between this skull and that from the Nean- 
derthal, the prominence of the supraorbital ridges in the latter is 
more marked, and they are completely continuous with the orbital

margin, which is not the case in the former. But the skulls are 
essentially distinguished by their general form, which in the one is 
long-elliptical, and in the other rounded." A portion of the upper 
jaw with the teeth, and the entire lower jaw, have been preserved, in- 
dicating that the Plau man was orthognathous. As ia most of these 
cases, the sole chemical evidence of the antiquity of the Plau skele- 
ton is, that " the bones are thick but very light, and adhere strongly 
to the tongue." More exact analysis of their component parts is 
unrecorded by Dr. Schauffhausen.

were associated, but in a way not known, with those of Elephas pri- 
mir/enius, Wiinoceros ticJwrhinus, 3Iegacet^os, etc., after their discovery, 
fell into the hands of the mayor of Aurignac. Not regarding the in- 
terests of science, and in order to prevent the dissemination of any 
hypotheses on the subject amongst the Gascons, he carefully collected
