it lives parasitically. Somewhat similar is the cocus insect, among whom the males are very degenerate, small, blind and wingless. This phenomenon of minute parasitic male fertilisers in connection with normally developed females was noticed by Darwin, and his observations have been confirmed by Van Beneden, by Huxley, Haeckel, Milne Edwards, Fabre, Patrick Geddes, and many other eminent entomologists.[22] A full study of these early forms of sexuality should be made by all who wish to understand the problem of woman; their life-histories furnish prophecies of many large facts. I wish it were possible for me to bring forward further examples. It is the difficulty of treating so wide a subject within narrow limits that so many things that are of interest have to be hurried over and left out. But there is one delightful case that I cannot refrain from mentioning. The facts are given in a letter from Darwin to Sir Charles Lyell, dated September 14, 1849. It is quoted by Professor Lester Ward. This instance of the sexual relationship among the cirripedes illustrates very vividly the early superiority of the female. The letter runs thus-- "The other day I got a curious case of a unisexual, instead of hermaphrodite cirripede, in which the female had the common cirripedial character, and in two valves of her shell had two little pockets, in each of which she kept a little husband; I do not know of any other case in which the female invariably has two husbands. I have still one other fact, common to several species, namely, that though they are hermaphrodite, they have small additional, or shall I call them, complemental males, one specimen, itself hermaphrodite, had no less than seven of these complemental males attached to it. Truly the schemes and wonders of Nature are illimitable,"[23] Here, indeed, is a knock-down blow to the theory of the natural superiority of the male. These cases we have examined are certainly extreme, the difference between the sexes is, as we shall see, less marked in many early types. But the existence of these helpless little husbands serves to show the true origin of the male. How often he lived parasitically on the female, his work to aid her in the reproductive process, useful to secure greater variation than could be had by the single-celled process. In other words, the male is of use to the life-scheme in assisting the female to produce progressively fitter forms. She, indeed, created him, his sole function being her impregnation.
