Closely related to the great feeble-minded class, and from time to time falling into crime, are the inmates of workhouses, tramps, and the unemployable. The so-called "able-bodied" inmates of the workhouses are frequently found, on medical examination, to be, in more than fifty per cent cases, mentally defective, equally so whether they are men or women. Tramps, by nature and profession, who overlap the workhouse population, and are estimated to number 20,000 to 30,000 in England and Wales, when the genuine unemployed are eliminated, are everywhere found to be a very degenerate class, among whom the most mischievous kinds of feeble-mindedness and mental perversion prevail. Inebriates, the people who are chronically and helplessly given to drink, largely belong to the same great family, and do not so much become feeble-minded because they drink, but possess the tendency to drink because they have a strain of feeble-mindedness from birth. Branthwaite, the chief English authority on this question, finds that of the inebriates who come to his notice, putting aside altogether the group of actually insane persons, about sixty-three per cent are mentally defective, and scarcely more than a third of the whole number of average mental capacity. It is evident that these people, even if restored to sobriety, would still retain their more or less inborn defectiveness, and would remain equally, unfit to become the parents of the coming generation. These are the kind of people--tramps, prostitutes, paupers, criminals, inebriates, all tending to be born a little defective--who largely make up the great degenerate families whose histories are from time to time recorded. Such a family was that of the Jukes in America, who, in the course of five generations, by constantly intermarrying with bad stocks, produced 709 known descendants who were on the whole unfit for society, and have been a constant danger and burden to society.[36] A still larger family of the same kind, more recently studied in Germany, consisted of 834 known persons, all descended from a drunken vagabond woman, probably somewhat feeble-minded but physically vigorous. The great majority of these descendants were prostitutes, tramps, paupers, and criminals (some of them murderers), and the direct cost in money to the Prussian State for the keep and care of this woman and her family has been a quarter of a million pounds. Yet another such family is that of the "Zeros." Three centuries ago they were highly respectable people, living in a Swiss valley. But they intermarried with an insane stock, and subsequently married other women of an unbalanced nature. In recent times 310 members of this family have been studied, and it is found that vagrancy, feeble-mindedness, mental troubles, criminality, pauperism, immorality are, as it may be termed, their patrimony.[37]
