 the cranium show the surface features of the brain. 

 As compared with the brain of modern man, it is 

 small in the region of the frontal lobes and shows a 

 greater simplicity in the pattern of the convolutions. 



A somewhat more primitive type was discovered a 

 few months earlier (March, 1908) at the famous 

 station of Le Moustier. It is the skull of a young 

 person and valuable for comparison. 



These aboriginal people represent one link of the 

 chain of human ancestry, and they were followed by a 

 higher developed type of primitive man before the 

 dawn of history and the emergence of the modern 

 type. 



A much more interesting circumstance is that 

 the Neanderthal people were preceded by more 

 primitive pre-humans. There are known at present 

 three examples of remains that are distinctly pre- 

 Neanderthaloid. The first to be discovered, and also 

 the most primitive pre-human species known, is 

 represented by portions of the skull, and of the leg 

 bones, found in Central Java by the Dutch surgeon, 

 Dubois, during the years 1891 and 1892, and made 

 known in 1894. These remains were found in Ter-
