Recently three children were presented at the Children's Dispensary of Schenectady. Two were, to all outward appearances, of the Mongolian type. The third, a twin of the younger, apparently perfectly normal.
The father and mother are seemingly healthy Italians, not of the lowest class. There had been no miscarriages, but four children in all, the fourth said to be well. A history of syphilis in the parents was not obtainable.
The mother's age at the time of birth of the older child, now 9 years, was 18. The second, now 8, was born when the mother was 20. The twins, 5 years old, one normal, the other diseased, were born when she was 22.
These ages of the mother at the time the several births occurred are mentioned because mongolism is likely to show itself in the offspring of women of advanced age, of women who have borne many children,
