BRAIN-WEIGHT AND SIZE IN RELATION 



51*5 oz. av., and the otlier only 738 grammes, or 26'1 oz. av. In 

 addition to each actual brain-weights, Morton, Tiedemann, Davis, 

 Wyman, and others, have gauged the skulls of Negroes, American 

 Indians, Mincopies, Tasmanians, Australians, and other savage races, 

 as well as those of many civilized and semi-civilized nations, and 

 thereby contributed valuable data towards determining their relative 

 cranial capacity. In his "Crania ^gyptiaca," Dr. Morton, when dis- 

 cussing the traces of a Negro element in the ancient Egyptian popu- 

 lation, says : "I have in my possession seventy-nine crania of 

 Negroes bom in Africa, for wJiich I am indebted to Drs. Goheen 

 and McDowell, lately attached to the medical department of the 

 colony of Liberia, in western Africa ; and especially to Don Jose 

 Rodriguez Cisneros, M.D., of Havana, in the island of Cuba. Of 

 the whole number, fifty-eight are adult, or sixteen years of age and 

 upwards, and give eighty-five cubic inches for the average size of the 

 brain. The largest head measures ninety-nine cubic inches ; the 

 smallest but sixty-five. The latter, which is that of a middle-aged 

 woman, is the smallest adult head that has hitherto come under my 

 notice."*
