In a second group of three families there were twenty children.

The fathers were drunkards, but their immediate ancestors were free: four children died of general weakness, three of convulsions in the first month, two were feeble-minded, one was a dwarf, one was an epileptic, seven were normal.

In a family in which both father and mother and their ancestors were drunkards there were six children: three died of convulsions within six months, one was an idiot, one a dwarf, and one an epileptic.

For comparison there were taken from the same station in life ten families in which there was no drunkenness: three children died from general weakness, three from intestinal troubles, two of nervous affection, two were feeble-minded, two were malformed, fifty were normal.

Legrain has studied on a larger scale the descendants of two hundred and fifteen families of drunkards in which there were eight hundred and nineteen children.
