TO RELATIVE CAPACITY OP RACES. 227 



man as 65 ; but it is manifest that the latter figures, if taken -with- 

 out reference to relative stature, furnish a very pai-tial index of the 

 comparative volume of brain. 



Professor Goodsir, as already noted, held that symmetry of brain 

 has more to do with the higher faculties than mere bulk. In the 

 case of the Peruvians the systematic distortion of the skull precludes 

 the application of this test. But in the small Hindoo skull the fine 

 proportions have been repeatedly noted. Dr. Davis, in describing 

 one of a Hindoo of unmixed blood, born in Sumatra, says : " His 

 pretty, diminutive skull is singularly contrasted with those of the 

 races by whom, alive, he was surrounded ;"* and he adds : " The 

 great agreement of the elegant skulls of Hindoos in their types and 

 proportions, although not in dimensions, with those of European 

 races, has afibrded some support to that wide-spread and learned 

 illusion, 'the Indo-European hypothesis.' The Hindoo skulls are 

 generally beautiful models of form in miniature." 



Mr. Alfred E.. Wallace, in his " Malay Archipelago," discusses the 

 value of cranial measurements for ethnological pu.rposes ; and, employ- 

 ing those furnished by Dr. J. B. Davis in his " Thesaurus Craniorum " 

 as a " means of determining whether the forms and dimensions of the 

 crania of the eastern races would in any way support or refute his 

 classification of them," he finally selected as the best tests for his 

 purpose — 1. The capacity of the cranium; 2. The proportion of the 

 width to the length taken as 100 ; 3. The proportion of the 

 height to the length taken as 100. But here again, unfortunately, 

 the systematic distortion of the Peruvian skulls limits us to the first 

 of those tests. There are, indeed, the eleven normal Peruvian crania 

 selected as such from the numerous Ancon skulls brought by Professor 

 Agassiz from Peru. But those are stated by Professor Wyman to 

 be on an average less by six inches than the ordinary skull. Some 

 partial results embodied in the following table admit of comparison 

 with those based on the more ample data of Table IX. Dr. Lucae, 

 in his " Zur Organischen Formenlehre," already referred to, gives 

 the cranial capacity of single skulls of difierent races, selected as 

 examples of each. In these, as in others already referred to, the 

 capacity was determined with peas ; and the results — assumed to be 

 given in Prussian ounces, — are dealt with here, as in the skulls of 

 Heinse and Bunger. The experiments carried on for the purpose of
