original sex, but continues throughout, the main trunk, though afterwards the male element is added "for the purposes of fertilisation." "Among millions of humble creatures," says Mr Ward, "the male is simply and solely a fertiliser." The writer goes on in his efforts to belittle the male sex in the sphere of biology. "The gigantic female spider and the tiny male fertiliser, the Mantis insect with its similarly large and ferocious female, bees, and mosquitoes," all are pressed into the service. Even the vegetable kingdom, in so far as it shows signs of sex differentiation, is brought into the lists in favour of his theory of female supremacy, or "gynæcocentricism," as he terms it.
This theory may be briefly stated as follows:—In the earliest organisms displaying sex differentiation, it is the female which represents the organism proper, the rudimentary male existing solely for the purpose of the fertilisation of the female. This applies to most of the lower forms of life in which the differentiation of sex obtains, and in many insects, the Mantis being one of the cases specially insisted upon by our author. The process of the development of the male sex is by means of the sexual selection of the female. From being a mere fertilising agent, gradually, as evolution proceeds, it assumes the form and characteristics of an independent organism like the original female trunk organism. But the latter continues to main-
