16 WILLIAM DALE, ESQ., P.S.A., F.G.S., ON PREHISTORIC MAN : 



and in a long and powerful argument, which only an anatomist 

 can really appreciate, it is shown how the development of those 

 areas of the brain connected with tactile, visual, and acoustic 

 impressions, and the storing of them in the chambers of memory, 

 brought about the human brain, and all those changes in man's 

 form which have differentiated him from some of the primates 

 from which he has sprung. 



Professor Sollas, who is a believer in the assumption of the 

 erect attitude as the prime factor in man's differentiation, concludes 

 the address from which I have already quoted, in these words : 

 " How little we really know concerning the true course of human 

 evolution is impressed upon us by the paucity of the evidence 

 which we are able to adduce directly bearing on such speculations 

 as we have considered." He then gives a quotation which, 

 although the words of Huxley, are worthy of a divine: ''Man alone 

 possesses the marvellous endowment of intelligible and rational 

 speech, whereby he has slowly accumulated and organized the 

 experience which is almost wholly lost with the cessation of life 

 in other animals, so that now he stands raised upon it as on a 

 mountain-top, far above the level of his humbler fellows, and 

 transfigared from his grosser nature by reflecting here and there 

 a ray from the infinite source of truth." 



In dealing with the few skeletal remains of man which we 

 are sure belong to a period anterior to the Neolithic Age, we are 

 m the more sober region of facts. Sir John Evans recognised 

 only two divisions of the Paleolithic period — the river drift and 

 cave periods. Led by French investigators, six are now widely 

 recognized, which in the sequence of their age are the Chellean, 

 Acheulean, Mousterian, Aurignacian, Solutrian, and Magdalenian. 

 The evidence of the sequence of these periods rests largely upon 

 the character of the implements which are assigned to them. All 

 English archaeologists do not, however, at present accept these 

 divisions, because in English gravel beds the various forms of 

 implements are so often found mixed together, that no stratifica- 

 tion is possible. Human remains have long been known from the 

 Magdalenian period. They give evidence of the existence of 

 two contemporary races. The Cro-Magnon race, a tall people of 

 a Mongolian type, and a race of short people like the modern 

 Eskimo. It is an extraordinary fact that both races were of 

 great cranial capacity, and endowed with larger brains than the 

 average of any existing civilized people. In the Solutrian Age 

 a race of men existed whose remains have been discovered on
