Relation of Age of Parents in Normal Persons, the Insane and Criminal.
It is interesting to compare these results with those of Korosi, Director of the Hungarian Statistical Bureau, on the ordinary population. He has investigated 24,000 cases, and found that the children of fathers below 20 are of feeble constitution; that fathers aged from 25 to 40 produce the strongest children, and that above 40 fathers tend to beget weak children. The most healthy children have a mother below the age of 35; the children born between 35 and 40 are 8 per cent. weaker; after 40, 10 per cent. weaker. The children born of old fathers and young mothers, it should, however, be added, are generally of strong constitution. If the parents are of the same age the children are less robust.
Such hereditary influences as these seem to have played a part in the production of that typical criminal by instinct, T. G. Wainewright, who appears to have had no criminals or lunatics among his ancestry. The often-quoted case of the criminal family, first mentioned by Despine in his Psychologie Naturelle, is interesting in this connection. Three brothers, the sons of one Jean Chrétien, had children and grandchildren as under—
| Jean Joseph | Jean-François, thief. Bénoît. Claire, thief. Marie-Renée, thief. Marie-Rose, thief. Victor, thief. Victorine. —— Victor, murderer. |
| Thomas | François, murderer. Martin, murderer —— (son, thief). |
| Pierre— | Jean-François, thief and murderer. |
Nothing is told us of the man and his three sons who produced this awful brood, save that they were not themselves condemned criminals; but whatever the influence was, it existed in all three of the brothers, who each begat murderers and thieves. It is by subtle hereditary influences, as well as by the instinctive habits of a lifetime, that we must explain the influence of criminal contagion on men of honest life and clean record. M. Émile Gautier, a political prisoner with Prince Krapotkine and a number of French working-men in the great prison of Clairvaux, has recorded an experience which is of interest in this connection. “Out of fifty political prisoners,” he writes in his interesting and thoughtful impressions published in the Archives de l’Anthropologie Criminelle in 1888, “belonging to the average, or even the élite, of the working-class population of a large town like Lyons, a good half-dozen will be found who feel themselves at home in prison, and go immediately towards the criminal-law prisoners, assuming at once, in virtue of I do not know what equivocal predestination, their language, their appearance, their habits, their mental dispositions, even the same negative morality, savagery, treachery, artfulness, rapacity, and unnatural vice.”
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.
