Analysis by race of 506 children in the cardiac clinic at Bellevue Hospital and 511 children in the general pediatric clinic indicates that certain races in New York City, Namely, Italian, Irish and nativeborn Americans, are somewhat more susceptible to rheumatism than certain other races. Certain other races, namely, Spanish, Armenian, and Jews, seem to be less susceptible.

Females are slightly more frequently affected with rheumatic heart disease than males.

The age at which most cases of rheumatism begin, without considering sex, is nine years. The average age at onset for boys is seven years, for girls nine years.

Twenty-one per cent of girls with rheumatic heart disease gave no history of rheumatic infection before the discovery of heart disease, while only 14 per cent of the boys gave no such history.

There is a definite seasonal incidence of rheumatism in New York City, which shows little variation in individual years. In general, the spring months show the highest incidence. For the five-year period studied, April and May contained the greatest number of cases. No correlation could be made between meteorological conditions and monthly incidence of rheumatism. In general, the height of the rheumatic season occurred at the time of year when the precipitation was lowest and the temperature rising, a finding contrary to that to be expected if Young's conclusions have general applicability.
