ciety. 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 to 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 greater adhesion to custom by women than by 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 adhere 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 comparisons of races made to determine the amounts and characters of the higher feelings to which the relation of the sexes gives rise. The lowest varieties of mankind have but small endowments of these feelings. Among varieties of higher types, such as the Malayo-Polynesians, these feelings seem considerably developed: the Dyaks, for instance, sometimes display them in great strength. Speaking generally, they appear to become stronger with the advance of civilization. Several subordinate inquiries may be named: (a.) How far is development of the sexual sentiment dependent upon intellectual advance—upon growth of imaginative power? (b.) How far is it related to emotional advance; and especially to evolution of those emotions which originate from sympathy? What are its relations to polyandry and polygyny? (c.) Does it not tend toward, and is it not fostered, by, monogamy? (d.) What connection has it with maintenance of the family bond, and the consequent better rearing of children?
III.—Under the third head, to which we may now pass, come the more special traits of the different races:
1. Imitativeness.—One of the characteristics in which the lower types of men show us a smaller departure from reflex action than do the higher types is, their strong tendency to mimic the motions and sounds made by others—an almost involuntary habit which travelers find it difficult to check. This meaningless repetition, which seems to imply that the idea of an observed action cannot be framed in the mind of the observer without tending forthwith to discharge itself in the action conceived (and every ideal action is a nascent form of the
