Ill THE NEANDERTHAL MAN 185 



notwithstanding the flattened condition of the 

 occiput, the posterior cerebral lobes must have 

 projected considerably beyond the cerebellum, 

 and as it constitutes one among several points of 

 similarity between the Neanderthal cranium and 

 certain Australian skulls. 



Such are the two best known forms of human 

 cranium, which have been found in what may be 

 fairly termed a fossil state. Can either be shown 

 to fill up or diminish, to any appreciable extent, 

 the structural interval which exists between Man 

 and the man-like apes ? Or, on the other hand, 

 does neither depart more widely from the average 

 structure of the human cranium, than normally 

 formed skulls of men are known to do at the 

 present day ? 



It is impossible to form any opinion on these 

 questions, without some preliminary acquaintance 

 with the range of variation exhibited by human 

 structure in general a subject which has been 

 but imperfectly studied, while even of what is 

 known, my limits will necessarily allow me to give 

 only a very imperfect sketch. 



The student of anatomy is perfectly well aware 

 that there is not a single organ of the human 

 body the structure of which does not vary, to a 

 greater or less extent, in different individuals. 

 The skeleton varies in the proportions, and even 

 to a certain extent in the connexions, of its con-
