858 THE SIZE AND WEIGHT 



It will be interesting to place next to this the table 

 given by Thurnam embodying the average results of the 

 weighing of twelve Negro brains. 



AVERAGE BRAIN-WEIGHT OP EUROPEANS AND NEGROES COMPARED. 



Males. Ounces. Grammes. Ratio of Brain- Weight. 



Europeans. ... 49 1390 . . 100 



Negroes (Tiedemann, 4) . 44 '2 1252 . . 90 

 (Peacock, 5) . . 44'3 1255 . . 90 

 (Barkow, 3) . . 44'5 1261 . . 90 



(Average, 12) . 44'3 1255 . . 90 



These observations, as Thurnam says, agree in " making 

 the Brain- weight of the male Negro the same as that of 

 the female European." He adds : " The decided influ- 

 ence of race on the weight of the brain is scarcely to be 

 questioned ; and there can be little doubt that the smaller 

 size of the brain in other melanous and lower races will 

 hereafter be made out by direct observation. The brains 

 of the Hindoo, Hottentot, Bushman, and Australian, are 

 probably of less weight even than that of the Negro; 

 but in all these comparisons the stature must be con- 

 sidered." * 



Kecords of the Brain-weight of males belonging to 

 these latter races are not as yet forthcoming ; but from 

 the ascertained weight of three female Bushwomen, as 

 well as from what we know of the cranial capacity of the 

 races mentioned, it may fairly be anticipated that their 



* There is some reason to believe that, to a certain extent, as we 

 go northwards the average human stature increases, and with it 

 the average cranial capacity and brain-weight. Yet the Lapps 

 and Esquimaux are extremely short, though their cranial capacities 

 remain unusually high.
