I do not like to advise marriage to parties in ill health; and yet, as a medical measure, this is often advisable. We have seen that a single life is for men, and on sanitary grounds, not the best. There are many cases where it is as unadvisable for women. As a class they need marriage, for a different reason than ourselves. Constructed as evidently for companionship, their yearnings are more mental than physical. They are less conscious of any bodily needs, that is, in their normal condition, but more craving of a spiritual sympathy; more angelic than ourselves, we may truly call them. The point to which I would now refer, however, is the fact that, in many instances, women are deterred from consenting to marriage upon the ground of their own ill health; and I merely shall say that, in very many instances, far more than is usually supposed, marriage would prove for such ill health the most certain cure. I do not make this remark too sweepingly, for there are some affections under which women suffer that would only be aggravated by the change; there are certain bars, as that of cousinship, which, on some accounts, ought never to be passed, and there are certain physical evils of which marriage is only but too productive. Plainly I would avow my conviction that just as marriage should be avoided among blood relations, for the reason that any family taint, as scrofula, deformity, or insanity, is thus rendered nearly certain to their children, so should the same similarity of constitution be avoided, so far as possible, by Cœlebs in search of a wife. If, selfishly, he would avoid defects in her, is it not his duty also to see to it that he brings to her a constitution of his own unmarred, so far as he himself has been concerned? And when, as is too often the case, men who carry with them a system infected by that terrible disease of the licentious, marry pure and unsuspecting women, a great outrage is committed upon society, which no penance and no individual suffering can ever efface or atone for. One of the worst features of this whole matter, as I shall hereafter point out, is as yet generally unknown—that the most ineradicable form of the disease has its period of incubation; the primary sign of it may escape notice, the virus may lie latent, and when it does exhibit itself, the party really to blame may throw the whole enormity of the trouble upon an innocent person, and thus, on the wreck he has made of his home, immolate its guardian.
