The commissioners conclude that, "if the other parts of the state contain the same proportion of idiots to their whole population, the total number in the commonwealth is between fourteen and fifteen hundred!" Now if we make the same estimate in proportion to the entire population, it will appear that in the United States there are upward of thirty-five thousand persons in the most wretched and helpless condition of idiocy.
In view of the great number of idiots in the commonwealth, the commissioners say, "it appeared to us certain that the existence of so many idiots in every generation must be the consequence of some violation of the natural laws; that where there was so much suffering there must have been sin. We resolved, therefore, to seek for the sources of the evil, as well as to gauge the depth and extent of the misery."
Some of the causes of idiocy are set forth in the report, two of which are as follows: first, the low condition of the physical organization of one or both parents, induced often by intemperance; second, the intermarriage of relatives.
The report states that out of 420 cases of congenital idiocy which were examined, some information was gained respecting the condition of the progenitors of 359. Now in all these cases, save only four, it was found that one or the other, or both, of the immediate progenitors of the unfortunate sufferer had in some way widely departed from the normal condition of health, and violated the natural laws. That is to say, one or the other, or both of them, had been very unhealthy or scrofulous; or hereditarily predisposed to affections of the brain, causing occasional insanity; or had intermarried with blood relatives; or had been intemperate; or had been guilty of sensual excesses which impair the constitution.[50]
Intemperance and Idiocy.—Out of the three hundred and fifty-nine idiots, the condition of whose progenitors was ascertained, ninety-nine were the children of drunkards. But this does not tell the whole story by any means. By drunkard is meant a person who is a notorious and habitual sot. Many persons who are habitually intemperate do not get this name even now; much less would they have done so twenty-five or thirty years ago. By a pretty careful inquiry, with an especial view of ascertaining the number of idiots of the lowest class whose parents were known to be temperate persons, it is found that not one quarter can be so considered.
From the pretty uniform action of a physiological law, which is now becoming well understood, it appears that idiots, fools, and simpletons, either in the first or second generation, are common among the progeny of intemperate persons, and may be considered as an effect of the habitual use of alcohol, even in moderate quantities. If, moreover, one considers how many children of intemperate parents there are who, without being idiots, are deficient in bodily and mental energy, and predisposed by their very organization to have cravings for alcoholic stimulants, it will be seen what an immense burden the drinkers of one generation throw upon the succeeding one.
Idiocy and the Marriage of Relatives.—Out of the three hundred and fifty-nine cases of congenital idiocy already referred to, in which the parentage was ascertained, "seventeen were known to be the children of parents nearly related by blood; but, as many of these cases were adults, it was impossible to ascertain, in some cases, whether their parents, who were dead, were related or not before marriage. From some collateral evidence, we conclude that at least three more cases should be added to the seventeen. This would show that more than one twentieth of the idiots examined are offspring of the marriage of relations. Now, as marriages between near relations are by no means in the ratio of one to twenty, nor even, perhaps, as one to a thousand to the marriages between persons not related, it follows that the proportion of idiotic progeny is vastly greater in the former than in the latter case. Then it should be considered that idiocy is only one form in which Nature manifests that she has been offended by such intermarriages. It is probable that blindness, deafness, imbecility, and other infirmities, are more likely to be the lot of the children of parents related by blood than of others. The probability, therefore, of unhealthy or infirm issue from such marriages becomes fearfully great, and the existence of the law against them is made out as clearly as though it were written on tables of stone.
"The statistics of the seventeen families, the heads of which, being blood relatives, intermarried, tells a fearful tale. Most of the parents were intemperate or scrofulous; some were both the one and the other; of course, there were other causes to increase chances of infirm offspring besides that of the intermarriage. There were born unto them ninety-five children, of whom forty-four were idiotic, twelve others were scrofulous and puny, one was deaf, and one was a dwarf! In some cases, all the children were either idiotic, or very scrofulous and puny. In one family of eight children, five were idiotic."
Condition of Idiots.—From what has been said of the character of parents to whom are born the greatest proportion of this most wretched and helpless class of persons, their condition and treatment might be inferred. To rear healthy children properly, a knowledge of the principles of physiology and mental science is essentially necessary. This knowledge is still more important in the treatment of idiots. Dr. Howe is of the opinion that it requires a rarer and higher kind of talent to teach an idiot than a youth of superior talent. When the time comes that schools for idiots are established all over the country, he thinks "it will be found more difficult to get good teachers for them than to get good professors for our colleges."
After excepting five or six alms-houses in which the idiots are treated both kindly and wisely, the commissioners say, "the general condition of those at the public charge is most deplorable. They are filthy, gluttonous, lazy, and given up to abominations of various kinds. They not only do not improve, but they sink deeper and deeper into bodily depravity and mental degradation. Bad, however, as is the condition of the idiots who are at public charge, and gross as is the ignorance of those who take the charge of them about their real wants and capabilities, we are constrained to say that the condition of those in private houses is, generally speaking, still worse, and the ignorance of the relatives and friends who support them is still more profound."
