Of 359 cases observed by Dr. Howe, 17 were known to be the children of parents nearly related in blood. The history of these 17 families, the heads of which being blood relatives intermarried, showed that there were other causes to increase the chances of an infirm offspring, besides that of intermarriages, as most of the parents were intemperate or scrofulous; some were both the one and the other. There were born unto them 95 children, of whom 44 were idiotic, 12 others were scrofulous and puny, one was deaf, and one was a dwarf! In one family of 8 children, 5 were idiotic.[9]
Dr. Ireland, who has investigated this point with great minuteness, pertinently remarks that it has been the custom to collect instances of cousins who have married, and have had unhealthy children, as if this never happened to anyone else; and he adds that "the proper way to examine the question clearly, is to find what is the proportion of marriages of blood relations in a given population, and then to inquire if there be in the issue of such marriages a larger percentage of insane, idiotic, or otherwise unhealthy children."[10]
There cannot be a doubt that consanguinity has hitherto been considered too great a factor in the production of idiocy, and that in weighing the evidence, we must not lose sight of the fact that in many cases recorded, other factors beside intermarriage of relatives have contributed concurrently to the development of the mental defect.[11]
Educational Overpressure. There is one cause of idiocy which has been pointed out by Dr. Séguin, and which he says is due to the unsatisfactory social conditions under which women of the present day exist. "As soon," he says, "as women assumed the anxieties pertaining to both sexes, they gave birth to children whose like had hardly been met with thirty years ago."[12]
Great prominence has lately been given to this subject by an oration on "Sex in Education," by Sir James Crichton Browne, at the Medical Society of London, in which he called attention to the "growing tendency to ignore intellectual distinctions between the sexes, to assimilate the education of girls to that of boys, and to throw men and women into industrial competition in every walk of life." Elsewhere, he adds, that "to throw women into competition with men is to insure to them a largely increased liability to organic nervous disease.... Woe betide the generation that springs from mothers amongst whom gross nervous degenerations abound." Sir J.C. Browne supports his views by showing that there are organic cerebral differences between men and women, and that therefore they must be educated in different ways, being destined to play different parts on the stage of human life.[13]
The above views of Sir J.C. Browne have not remained unchallenged, and the eminent psychologist has found uncompromising opponents in Mrs. Garrett Anderson and others, who stoutly refuse to recognise the position of the "Tacens et placens uxor" of old-time dreams. Mrs. Anderson, who, I need scarcely add, writes most temperately upon this matter, in alluding to Sir J.C. Browne's assumption of the intellectual difference between men and women, remarks, "All I would venture to say is that, if it could be proved that an average man differs from an average woman as much as Newton differed from a cretin, it would still be well to give the cretin all the training which he was capable of receiving.... When we hear it said that women will cease to be womanly if they enter professions or occasionally vote in parliamentary elections, we think that those who conjure up these terrors should try to understand women better, and should rid themselves of the habit of being frightened about nothing."[14]
The limits of this essay will not permit me to dwell at any great length on the important question under consideration. There cannot be a doubt that the tendency of the present age is to encourage women to choose careers and to accept burdens unfitted for them. In thus expressing myself, I distinctly deprecate any hostility to the woman's movement of the present day, which rests on the claim for women for an open career; and I should be glad to see our universities ignore the ancient and exploded prejudices, which led to the long subjection of women to hardship and inequality. They ask for the same facilities as are enjoyed by men, and they have amply shown that they can compete with men in intellectual pursuits, and all they ask is to be allowed to compete on equal terms. I therefore cordially welcome the gradual emancipation of women from comparative subjection to comparative freedom; but the multifarious fields of energy and usefulness open to modern women, have brought with them disadvantages as well as gains.
Whilst, therefore, unreservedly admitting the claims of the fin de siècle woman to freedom of action and to intellectual equality, I must think there are certain branches of study, described by a modern writer as belonging to the "gynagogue" class, which are less suited to women than some others; and amongst these, I would name the abstruse study of mathematics, for although success in this branch of knowledge may lead to a brilliant career as a high wrangler, I think that a female mathematical athlete is not suited for the duties and responsibilities of maternity, and that the mental endowments of her children are likely to be below the average.
I am quite aware that I am treading on dangerous and delicate ground, but although I would not discourage the highest aspirations of women, whether of an intellectual, social, or æsthetic character, I must think that a word of caution is necessary against the overpressure of the present day in the direction above indicated.[15] With every desire to treat this question from a liberal point of view, I desire to emphasise the fact that men and women have different parts to play on the stage of life, and should be trained differently; but provided mental overpressure is guarded against, I have no fear of women engaging in certain occupations which custom has not hitherto recognised as feminine, and experience has shown us that they may be safely left to follow the promptings of their own powers and instincts.
