DR. J. BARNARD DAVIS ON THE WEIGHT OF THE BRAIN 
increased weight of brain. The 13 Lepchas, which include almost an equal number 
of men and of women, give a mean of 44-08 oz., or 1249 grms. 
9. Bodos. 10. Bhotias. — These two races agree in having an equally increased 
weight of the encephalon, the first of 45-97 oz., or 1303 grms., and the second of 
45-90 oz., or 1301 grms. 
11. Mishmees. 12. Singpho. 13. Nagas. — These three races of Assam, of whom we 
have male skulls only, agree in presenting a brain- weight in the medium of 47 '80 oz., 
or 1355 grms. 
14. Siamese. — The people of Siam are represented by 7 crania, 4 of men and 3 of 
women, and they come slightly below the races of Assam, the mean being 47-14 oz., 
or 1336 grms. 
15. Chinese. — The Chinese are well represented by 33 skulls, 25 of men and 8 of 
women, or about three-fourths those of men. The mean of the series reaches to 47-00 oz., 
or 1332 grms*. 
16. Burmese. — These 5 skulls of men prove that the races of Assam, Siam, China, and 
Burmah agree in the relative volume of brain, which is a mean on a par with the 
general mean of European races. 
17. Japanese. — From the examples here given, which, however, are only one skull of 
each sex, it might be considered that the Japanese suffer a serious diminution of brain- 
weight from their neighbours the Chinese and others. The mean of the two is only 
40-32 oz., or 1143 grms. Further observations will probably correct this conclusion. 
18. Ainos. — The European-looking skulls of the Amos of Yesso, present a brain- 
Aveight decidedly greater than the Japanese of this Collection. 
It will be seen that the general average of the 210 skulls of Asiatic Races is 44‘44 oz., 
or 1259 grms. That of the European Races was 47-12 oz., or 1335 grms., which shows 
a difference of 76 grms. in favour of Europeans. 
Table III. — African Races. 
In proceeding to the African Races we commence with 
1. Berbers , and 
2. Guanches, the old inhabitants of the Island of Teneriffe. These were people with 
somewhat small brains ; the mean of the series of 21 skulls, the great majority of which 
are those of women, is 43-49 oz., or 1233 grms.f. 
* The mean stature of 26 Chinese men was found by Dr. Weisbach to be 1630 millims., or 5 feet 4-2 inches, 
of 3 Chinese women 1475 millims ., or 4 ft. 10 inches. 
t The Guanches, unlike the Negroes of the adjoining Continent, were a race of small stature. The mummy 
at Cambridge measures 4 feet 10 inches, that of the man in the Museum of the Royal College of Surgeons of 
England is of the same height, and that of another man in the Museum of the Jardin des Plantes is half an 
inch taller. The skeleton of the woman in this last collection I found to measure only 4 feet 4 inches. It was 
a singular misconception on the part of Baron Al. yon Humboldt, who said the Guanches were famed for their 
tall stature, being the Patagonians of the Old World.
