The Influence of the Male Sexual Element on the Female Organism.-- Dr. Alexander Harvey, of Aberdeen, has adopted the theory of fetal inoculation. He believes that the effect is first due to the influence of the male element upon the ovum, which, in consequence of the subsequent close attachment and freely inter-communicating blood-vessels between the modified embryo and the mother, inoculates the condition of the mother with the qualities of the male; and so, on the subsequent impregnation by another male, the offspring resembles the first male and not its real parent. He even goes further, and says that it is conceivable, by successive impregnations effected by him, that the influence may be increased, and if so the younger children begotten by him, rather than the elder, might be expected, ceteris paribus, to bear their father's image. And as regards the mother, he suggests the question, whether there is not something in the popular notion that in the course of years the wife comes to resemble the husband; and that not merely in respect of temper, disposition, or habits of thought, but in bodily appearance, which may be referable to this influence exerted by the husband on her constitution, through the medium of the fetuses in utero. "Yet it shall be; thou shalt lower to his level day by day, What is fine within thee growing coarse to sympathize with clay. As the husband is the wife is; thou art mated with a clown, And the grossness of his nature will have weight to drag thee down. He will hold thee, when his passion shall have spent its novel force, Something better than his dog, a little dearer than his horse." Darwin, on the other hand, considers it a most improbable hypothesis that the mere blood of one individual should affect the reproductive organs of another individual in such a manner as to affect the subsequent offspring. The analogy, he says, from the direct action of the foreign pollen on the ovaries and seed coats of the mother plant strongly supports the belief that the male element acts directly on the reproductive organs of the female, and not through the intervention of the crossed embryo. Dr. John Brown, in reviewing the subject, says it must be conceded that the male element has an influence on the female, over and above its fertilizing influence upon the ovum. The limit of this influence is at present unknown. Heredity.-- Girls are more apt to resemble their fathers in mental traits, disposition, and constitution; while boys take after their mothers. Boys procreated by intelligent mothers will be intelligent; while it does not always follow that the sons of intelligent fathers are intelligent. The poets Burns, Ben Johnson, Goethe, Walter Scott, Byron, and Lamartine were all born of women remarkable for vivacity and brilliance of language.
