DB. J. BABNABD DAVIS ON THE WEIGHT OF THE BBAIN 
was an average brain-weight of 47 '9 oz., or 1358 grms., i. e. two ounces more than our 
mean. 
The results derived from our 16 French skulls may be compared with those obtained 
by Professor Paul Bkoca from carefully gauging the internal capacities of a large series 
of French crania of both sexes*. These were 115, derived from a vault in the Cite at 
Paris, and considered to be of the XII. th century, which gave a mean capacity of 1425 
cub. centims. ; 117 derived from the Cemetery of the Innocents, having a mean capacity 
of 1409-031 cub. centims. ; and 125 others from the Cemetery de l’Ouest, at Paris, skulls 
of the XlX.th century, which gave a slightly greater internal capacity, viz. 1461-53 cub. 
centims. By first of all subjecting these figures to our rule of the deduction of 15 per 
cent., and then reducing them to the weight of brain they represent, the following results 
are produced. The 115 French skulls of the Xll.th century must have held brains 
averaging 44*37 oz., or 1257 grms. ; those of the Innocents, 43 - 93 oz., or 1245 grms. ; 
and those of the XlX.th century, 45-46 oz., or 1288 grms. This gives a mean of the 
whole 357 French crania, which are both those of men and women, the relative number 
of the two sexes not having been stated, of 44’58 oz., or 1263 grms., only 17 grms. 
below our reduced general average, — a result which shows a remarkable agreement 
between the two different series of observations. Besides which it seems to indicate 
that the rough allowance of 1300 grms. to the French brain, by Professor Huschke, is 
sufficiently liberal. 
11. Italians . — 15 skulls of Italians, 13 those of men and only 2 those of women, give 
averages agreeing closely with those deduced from the crania of the two sexes of English. 
Dr. Weisbach gauged the skulls of 27 Italian men of the Austrian dominions, and his 
observations, when reduced to our standard, give an average of 46-19 oz., or 1309 grms.f, 
again closely agreeing with our series, which afford 47'58 oz., or 1348 grms. 
12. Lapps . — 7 skulls of Lapps, of pure blood, exhibit weights of brain very nearly 
equal to those of our Italians, and the same as the Italian men of Dr. Weisbach J. 
13. Swedes . — 12 skulls of Swedes, three-fourths of which are those of men, present a 
general mean closely agreeing with that of the English. 
14. 15. Frisians , Dutch . — These skulls again agree in brain-weight with the English. 
16. Germans .— Of these there are 13 males and 2 females, or a great predominance 
of the skulls of men, i. e. about six-sevenths. Hence it might be anticipated that our 
mean would be high. It is 50-28 oz., or 1425 grms. It is probable that our crania of 
the men are unusually large, and those of the 2 women seem to be unusually small. 
The mean of the series of German skulls exceeds our English mean. 
The late Professor Huschke weighed a number of brains of Germans, and these are

X The Lapps are short people. Among 8 Lapp men the mean stature was found to be 5 ft. 0-3 in., among . 
3 Lapp women the mean was 4 ft, 8'7 in. Notwithstanding this low stature the brain-weight of the Lapps is 
seen to be considerable.
