question--Do not the mental natures of the sexes in alien types of Man
diverge in unlike ways and degrees?

4. _Causes of the differences._--Are any relations to be traced between
these variable differences and the variable parts the sexes play in the
business of life? Assuming the cumulative effects of habit on function
and structure, as well as the limitation of heredity by sex, it is to be
expected that if, in any society, the activities of one sex, generation
after generation, differ from those of the other, there will arise
sexual adaptations of mind. Some instances in illustration may be named.
Among the Africans of Loango and other districts, as also among some of
the Indian Hill-tribes, the men and women are strongly contrasted as
respectively inert and energetic: the industry of the women having
apparently become so natural to them that no coercion is needed. Of
course, such facts suggest an extensive series of questions. Limitation
of heredity by sex may account both for those sexual differences of mind
which distinguish men and women in all races, and for those which
distinguish them in each race, or each society. An interesting
subordinate inquiry may be, how far such mental differences are inverted
in cases where there is inversion of social and domestic relations; as
among those Khasi Hill-tribes, whose women have so far the upper hand
that they turn off their husbands in a summary way if they displease
them.

5. _Mental modifiability in the two sexes._--Along with comparisons of
races in respect of mental plasticity may go parallel comparisons of the
sexes in each race. Is it true always, as it appears to be generally
true, that women are less modifiable than men? The relative conservatism
of women--their greater adhesion to established ideas and practices--is
manifest in many civilized and semi-civilized societies. Is it so among
the uncivilized? A curious instance of stronger attachment to custom in
women than in men is given by Dalton, as occurring among the Juangs, one
of the lowest wild tribes of Bengal. Until recently the only dress of
both sexes was something less than that which the Hebrew legend gives to
Adam and Eve. Years ago the men were led to adopt a cloth bandage round
the loins, in place of the bunch of leaves; but the women adhered to the
aboriginal habit: a conservatism shown where it might have been least
expected.

6. _The sexual sentiment._--Results of value may be looked for from
