TO HELATIVE CAPACITY OF RACES,

exceptional examples of unusually large skulls may be looked for in 

 all races; and a few of such abnormal Peruvian or otter skulls 

 would modify the mean capacities and weights in tbe following 

 table. Nevertheless the average results, as a whole, are probably a 

 close approximation to the truth :

Looking for some definite results from the various data here pro- 

 duced, the deductions to which they seem to point may be thus 

 stated. While Professor Wyman justly remarks that the relative 

 -capacity of the skull, and consequently of the encephalon, is to be 

 considered as an anatomical and not as a physiological characteristic, 

 relative largeness of the brain is nevertheless one of the most distin- 

 guishing attributes of man. Ample cerebral development is the 

 general accompaniment of intellectual capacity, alike in individuals 

 and races; and microcephaly, when it passes below well defined 

 limits, is no longer compatible with rational intelligence ; though it 

 amply suflB.ces for the requirements of the highest anthropomorpha. 

 Wagner thus definitely refers the special characteristics which sepa- 

 rate man from the irrational creation to one member of the ence- 

 phalon : " The relation of the lobes of the cerebrum to intelligence 

 may, perhaps, be expressed thus : there is a certain development of 

 the mass of the cerebrum, especially of the convolutions, requisite in
