Alcoholism in either of the parents is one of the most fruitful causes of crime in the child. To the drunkenness of Jupiter when Vulcan was conceived the Romans attributed the deformity of that god; in the words of the old Latin poet:-- “Quis nescit crudo distentum nectare quondam Indulsisse Jovem Junoni; atque inde creatum Vulcanum turpem, coelique ex arce ruendum?” There is to-day no doubt whatever that chronic alcoholism as well as temporary intoxication at the time of conception modifies profoundly the brain and nervous system of both parent and offspring. Some of the most characteristic cases of instinctive criminality are solely or chiefly due to alcoholism in one of the parents. When insanity and alcoholism are combined in the parents, a rich and awful legacy of degeneration is left to the offspring. Thus, one among many instances, Morel quotes a case in which the father was alcoholic, the mother insane, and of the five children one committed suicide, two became convicts, one daughter was mad, and another semi-imbecile. Carefully-drawn statistics of the 4000 criminals who have passed through Elmira, New York, show drunkenness clearly existing in the parents in 38.7 per cent., and probably in 11.1 per cent. more. Out of seventy-one criminals whose ancestry Rossi was able to trace, in twenty the father was a drunkard, in eleven the mother. Marro found that on an average 41 per cent. of the criminals he examined had a drunken parent, as against 16 per cent. for normal persons. Nor is it necessary that the alcoholism should be carried so far as to produce great obvious injury to the parent. The action of the poison may be slow and carried on from generation to generation. The fathers eat sour grapes; the children’s teeth are set on edge.
