In following up the chain of evolution in animal life from its inception in primordial protoplasm to its end, as we now find it, we discover that the interlinking organisms are, in the beginning, either asexual or hermaphroditic. The moneron, the lowest form of animal life, simply multiplies by division. The different elements through which propagation and generation are carried on, are undoubtedly present even in the moneron, but are not differentiated. The moneron is an organless, structureless organism, consequently asexual. The cell, on the contrary, is hermaphroditic, for it contains within itself the necessary elements for reproducing itself. The am[oe]ba is the connecting link which connects all terrene life with primitive bathybian protoplasm, and is, strictly speaking, a true hermaphrodite. Ascending at once to the sixth stage in the ancestry of man, we come to the _acoelomi_, or worms without body cavity. These worms are phylogenetic, consequently hermaphroditic. I do not mean to say that these worms have the organs of each sex equally developed; therefore, in the use of the word hermaphrodite, I use it in its broadest sense. I simply mean that they are autogenetic. In the _rhabdocoela_ the sexual organs appear in their simplest forms--a testis anterior to a single or double ovary. Other gliding worms have a more complex arrangement of the sexual organs, but most of them are true hermaphrodites. Next in the chain of evolutionary development, and one step nearer man, we find the soft worms (_scolecidae_); from a branch of this family the parent group of vertebrates was developed. The immediate ancestor of the vertebrates was either the amphioxus (lancelet) or some other notochordate animal, whose type is now extinct. Thus we have traced hermaphroditism from the am[oe]ba to the amphioxus, from the ancestor of the parent cell to the ancestor of the vertebrates. We could carry it further, but it is unnecessary. Effemination and viraginity, are due directly to the influence of that strange law laid down by Darwin--the law of reversion to ancestral types. It is an effort of nature to return man to the old hermaphroditic form from which he was evolved. It is an effort on the part of nature to incorporate the individualities of the male and female, both physical and psychical, in one body. The phenomenon of atavism is more apt to occur in feeble types than in strong, healthy and well-developed types. Microcephalism, occurring, as it most frequently does, among ignorant, ill-nourished, and unhealthy people, is an example. Dolichocephalism and a flattening of the cranial arch, with corresponding loss of capacity in the skull--types that we see everywhere among the depraved and vicious--are other examples of this tendency of atavism to seize on weakened and unhealthy subjects. Effemination finds more victims among the wealthy and the educated than among the poor and uneducated. This phenomenon is a psychic rather than
