These are the following: 1—Alcohol; 2—Tuberculosis; 3—Sexual Immorality; 4—Paralysis, Insanity, Epilepsy, Neurotic Condition, Syphilis, Criminality, Deafness, Blindness, Migraine, Goitre, Vagrancy. Page 473. Sexual immorality is closely associated with hereditary feeble-mindedness. Closely connected with the subject of sexual immorality is the one of illegitimacy. Our records show 278 illegitimate children of whom 259, or 93% are in the pure Hereditary group, 12 in the Probably Hereditary group, 3 in the Neuropathic, and 4 in the Accident group. There is nothing new in these facts. They are simply confirmatory of what we have found in other lines. Page 499. The feeble-minded person is not desirable; he is a social encumbrance, even a burden to himself. In short, it were better, both for him and for Society had he never been born. Should we not then in our attempt to improve the race begin by preventing the birth of more feeble-minded? Page 558. _THE FEEBLE-MINDED A SOCIAL DANGER. A. F. Tredgold, L.R.C.P., London. M.R.C.S., England. Medical Expert to the Royal Commission on the Feeble-minded, etc. Eugenics Review. Vol. 1, April, 1909. Pub. Eugenics Education Society, London._ In England and Wales on January 1st, 1906 there were a total of 138,529 persons in the country who were defective in mind. This corresponds to 4.03 per thousand population, or to one mentally defective person in every 248. In England and Wales on January 1st, 1906, there were no less than 125,827 insane persons. If we add these to the number of the mentally deficient which I have just stated, we find that in this country there is one person out of every 130 who suffers from severe disease of the mind.
