There are so many phases of the problem of blood pressure that I shall limit myself to dealing with a recent investigation of the mortality on lives accepted as “standard risks” by the New York Life Insurance Company.

The experience investigated was that of new policies issued from 1925 to 1936, inclusive, observed from entry until the anniversaries of the policies in 1937. The investigation was by policies and was divided into two groups, (a) those in which there was no impairment, and (b) those in which there appeared minor impairments but not of sufficient moment to place the policyholders in a substandard group. The expected deaths were obtained according to the company's standard experience for the same years of issue and exposure. The total number of policies emerging by death was 9552.
