Sinossi
Excerpt from The Law of Inheritance: Or the Philosophy of Breeding
The ovum takes its origin from within the stroma, or the cavity of the ovaries, which answer analogically to the secret ing process of the testicle. In many of the lower animals the testes and ovaries bear a close resemblance to each other, and the same holds good in the early or embryotic condition of the generative apparatus of man. In some of the lower grades of animals, as generally in the articulates and mol lusks, the ovaries have a glandular character, but in the verti brates the ova are evolved in the midst of a solid fibrous tissue or stroma.
The likeness between the spermatozoa and the ova is again indicated by the fact that they both appear to be the product of cell-action, with development having taken place after the dehiscence of the cell from its companion cells. We thus have in the sperm the mother-cell containing the nuclei which are formed into ciliated cells, and which are to develop a vitality sufficient to support the motion necessary to them for the fulfilment of their uses. In the ovum we recognize an advanced development, in which the cell containing its nucleus is the essence; the nucleus in both being the essential part for the exercise of the complete function of either, - the pro duction of the individual life.
