counts, and there is no means of ascertaining what 

 the variations of weight in the cortex are (it is 

 perhaps usually about 37 per cent, of the brain 

 weight, but this figure must have many vari- 

 ations) from the cranial capacity, or even from the 

 brain itself, still less of enumerating the neurons 

 which it contains or the connections which they 

 possess. " How far are we, then," says Deniker, 

 " from the true appreciation of cerebral work, 

 with our rude weighings of an organ in which, 

 with one part that would assuredly help us to the 

 solution of the problem, we weigh at least three 

 other parts having nothing, or almost nothing, to 

 do with it ? And even if we succeeded in finding 

 the number, the weight, and the volume of the 

 neurons, how are we to estimate the innumerable 

 combinations of which they are capable ? The 

 problem appears almost insoluble." 



Within limits, then, the size of the brain has 

 little or no correlation with the intellectuality of 

 its possessor. But within what wide limits. Let us 

 take the lower limit and see how small a brain 

 may be associated with average, or even more than 

 average, abilities. I leave aside the question of the 

 brains of small and pigmy races, though on that 

 point it may be said that the Andamanese and 

 other small races appear to have intelligences fully 

 as great as those of other savage, uneducated and 

 undeveloped races. But I will take another in- 

 stance which will bear out the point which I wish 

 to make that the size of the brain is not an index 

 to the intellectual capacities of its owner. Amongst
