RECENT discoveries have filled up to a great extent the gaps in our knowledge of Palæolithic man. The skeleton find in the lower grotto of Le Moustier (Dordogne) in the main confirms Klaatsch's conclusions, based on a comparison of the face-skeleton of the Neanderthal race with that of the present Australians. Homo mousteriensis belongs to the older Diluvial race, that is, to the Neanderthal type, not to Homo sapiens found in more recent Diluvium. The subject was about sixteen years old probably a male. That Homo mousteriensis belongs to the Neanderthal type is further shown by the character of the femur and radius (of which the length is estimated at 195 mm., while the upper arm measures 210 mm.). The Neanderthal race had short extremities, in which fact Klaatsch sees an approximation to the present Arctic races of Mongoloid relationship.
