In thus expressing myself, I should be sorry that my remarks should be construed as intended to cast any imputation upon those who have unfortunately an idiot in their family; the cause of the evil may be in some remote progenitor, for the transmission of the infirmity is not always direct, and the neurotic tendency may skip a generation, or be traced even further back. _Intemperance._ One of the most fruitful causes of idiocy is the _abuse_--mark, I do not say the _proper use_--of alcoholic stimulants, which tends to bring families into a low and feeble condition, which thus becomes a prolific cause of idiocy in their children. From a report on idiocy, by Dr. Howe and other Commissioners appointed by the Governor of Massachusetts to ascertain the causes of this calamity in that State, it is stated that "out of 359 idiots, the condition of whose progenitors was ascertained, 99 were the children of inveterate drunkards;" and the report goes on to say further, "that when the parents were not actually habitual drunkards, yet amongst the idiots of the lower class, not one quarter of the parents could be considered as temperate persons. From a table drawn up by the late Dr. Kerlin, an American physician, in which the causes of the infirmity are given in 100 cases of idiotic children, I observe that in 38 of the number, intemperance on the part of the parents is traced as an accessory, main, direct, or indirect cause. At the annual meeting of the British Medical Association, held at Cambridge, Dr. Fletcher Beach read a paper on the Intemperance of Parents as a predisposing cause of idiocy in children. In 430 patients, he was enabled to trace a history of parental intemperance in 138 cases, or 31·6 per cent.; of this number, 72 were males and 66 females."[5] Other observers lay less stress upon parental intemperance as a cause of idiocy. Dr. Wilbur found that out of 365 cases in the State of Illinois, only eight cases were assigned to the abuse of drink in the parents; and Dr. Shuttleworth could trace this cause in only 16·38 per cent. of the cases observed by himself and by Dr. Fletcher Beach;[6] the same writer, under the head of toxic idiocy, mentions the case of an idiot boy, who was said to have been brought up on porter instead of milk. It will therefore be seen that there exists a great difference of opinion about the influence of intemperance of the parent in the causation of idiocy; but although statistics may vary upon this point, there cannot be a doubt that the children of drunken parents inherit an unhealthy nervous system, which in many cases culminates in idiocy. Idiocy is especially prevalent in Norway, and Ludwig Dahl, a Norwegian writer, says that to the abuse of brandy, especially in the fathers, but also in the mothers during pregnancy, may be assigned an important, perhaps the most important, influence in the production of the large number of idiots in that country.
