parasite female class in our own societies today to pass away, French fashions with their easeless and grotesque variations (shaped not for use or beauty, but the attracting of attention) would die out. And the extent to which any woman today, not herself belonging to the parasite class and still labouring, attempts to follow afar off the fashions of the parasite, may be taken generally as an almost certain indication of the ease with which she would accept parasitism were its conditions offered her. The tendency of the cultured and intellectually labouring woman of today to adopt a more rational type of attire, less shaped to attract attention to the individual than to confer comfort and abstain from impeding activity, is often spoken of as an attempt on the part of woman slavishly to imitate man. What is really taking place is, that like causes are producing like effects on human creatures with common characteristics.) But there remain certain psychic differences in attitude, on the part of male and female as such, which are inherent and not artificial: and, in the psychic human world, it is exactly as we approach the sphere of sexual and reproductive activity, with those emotions and instincts connected directly with sex and the reproduction of the race, that a difference does appear. In the animal world all forms of psychic variations are found allying themselves now with the male sex form, and then with the female. In the insect and fish worlds, where the female forms are generally larger and stronger than the male, the female is generally more pugnacious and predatory than the male. Among birds-of-prey, where also the female form is larger and stronger than the male, the psychic differences seem very small. Among eagles and other allied forms, which are strictly monogamous, the affection of the female for the male is so great that she is said never to mate again if the male dies, and both watch over and care for the young with extreme solicitude. The ostrich male form, though perhaps larger than the female, shares with her the labour of hatching the eggs, relieving the hen of her duty at a fixed hour daily: and his care for the young when hatched is as tender as hers. Among song-birds, in which the male and female forms are so alike as sometimes to be indistinguishable, and which are also monogamous, the male and female forms not only exhibit the same passionate affection for each other (in the case of the South African cock-o-veet, they have one answering love-song between them; the male sounding two or three notes and the female completing it with two or three more), but they build the nest together and rear the young with an equal devotion. In the case of the little kapok bird of the Cape, a beautiful, white, fluffy round nest is made by both out of the white down of a certain plant, and immediately below the entrance to the cavity in which the little female sits on the eggs is a small shelf or basket, in which the tiny male sits
