In a few cases such as Huntington's chorea (Figs. 26, 27, pp. 114, 115) we can proceed with a fair degree of assurance, for we know that this dreadful malady is transmitted as a positive trait and that in all probability half of the children of an afflicted individual will inherit the defect. Such patients, if they ever rally sufficiently temporarily to leave the hospital, or where encountered outside the hospital should certainly be restrained from procreation. It is questionable if even their children, though apparently normal, should be allowed to have offspring, for usually the disorder does not manifest itself until middle life and then it is too late to try to prevent its transmission since the affected individual has already probably married and had children. But Huntington's chorea is a comparatively rare form of insanity, and one of only a few about which our knowledge as regards its transmissibility is fairly satisfactory. =In Feeble-Mindedness.--=When we come to institutions for the feeble-minded, however, there seems to be much more unanimity of opinion among physicians in charge of such institutions that sterilization would be an effective and satisfactory disposition to make of many cases, if we are to release the patients in question from custody. Unquestionably in cases of imbecility it is easier than in insanities to pass conclusive judgment on the inheritability of the condition in a large class of cases. Practically all are agreed that either permanent custodial care through the reproductive period or sterilization should be enforced. Some maintain that such individuals should remain permanently in institutions anyway and that therefore to sterilize them is needless, while others urge that if sterilized many capable of making their own living could be freed and allowed to do so. According to Goddard the feeble-minded woman is about three times as likely to find a mate as a feeble-minded man, hence it would seem to be of much greater importance to sterilize the woman than the man. Again it might be urged with much justification, that even though sterilized, the feeble-minded individual because of lack of self-control will transgress sexually and will thus certainly become a menace to society in the spread of venereal diseases. If Mr. Hart's estimate is anywhere near correct, that there are 60,000 feeble-minded women in the United States of child-bearing age, and that 13,000 are already in custody, then the task of getting all women of this class into custody is not so insurmountable as would at first appear.
