THE BRAIN.
It's Volume in Proportion to Intelligence

At the recent AnthrOpological Congressin Paris
DR.. Lebon gave the results of his experimental re-
searches on the variation of volume of the crani-
um in relation to intelligence. According to OBJ
servations made on numerous series OF crania 1t is
proved that intelligence is in proportion to the
volume of the Uranium, the best endowed races,
and among races, the most intelligent individ-
uals having the most voluminous cranium.-
By comparing these series of erania it is also found
that the superior races present much greater
number of voluminous crania than the others
The same phenomenon is presented in proportion
to the degree of civilization the Partisan crania
of the twelfth century present, for example, less
volume than the crania of modern Parisians. At
the same time, the difference among individuals
become more considerable. DR.. LebOn does not
believe that height exercises any considerable in
huence on the volume of the Uranium and the
weight of the brain. Nevertheless, with equal
height the woman has a brain less heavy than the
man. The author, from study OF seventeen male
and seventeen female brains, found between them
a difference of 172 grammes to the advantage Of
the former. 1t is worthy of remark, that among
the superior races the Uranium of the woman is
generally much less than among the inferior races.
This is due DIR. Lebon says, to the insignificant
part taken by woman in the work of modern
ciety. The comparative study of the curves OF the
circumference of the Uranium, of that of the head,
of the volume and weight Of the brain, shows the
relations existing between these various values
and renders possible the construction OF tables
which, one of them being known, permit the i'm
mediate determination of the others Of the series.
1t is seen, for example, that head the eircumfer
ence of which is 81 centimetres corresponds to
Uranium the circumference of which is 81 centime-
tres, and the volume 1850 cubic eentimetres.-
The probable weight of the brain contained in the
Uranium would be 1850 grammes. There is
constant inequality of development between the
two halves of the brain, which is sometimes more
developed on the right, sometimes on the left, with
out race or state of intelligence appearing to have
any manifest influence on the direction of this in
equality of development. The circumference OF
the Uranium, on which depends the volume of the
brain, has close connection with the degree OF
intelligence. With the measurements OF the cir
cumference of the head, taken from more than l.
200 living subjects, DIR. Lebon has constructed
series of curves which show that from the point
of view of their development the heads of modern
Parisians and of the inhabitants OF the country
are classed in the following order: ], Savants
and learned men 2, the Partisan bourgeoisie ),
the Old Nobility 4, Partisan Domestic Servants;
s. Peasants DR.. Broca, in remarking on Or.
Lebon's paper said that if among the less civilized
races the difference between the volume of the
crapia of men and women is relatively small,
while it is great among civilized races this does
not prove the intellectual inferiority of women,
but is explained by the necessity for savage women
taking part in the struggle for existence under the
same conditions as the men.
