of decedents from diseases of the heart, show in periods of twenty years each of life, the following percentages:

It will be seen that about 41 per cent. of all the deaths from diseases of the heart were of persons over sixty years of age, and under eighty.

Diseases of the heart have acquired large importance as a cause of death. From 28.8 in every 1,000 deaths from all causes, in 1865, heart diseases have gradually increased to about 64 in every 1,000, in 1888.

INSANITY.

There were 43 deaths from insanity, in 1888, a decrease of 21 from 1887. The percentage to the whole number of deaths was a trifle over six-tenths of one per cent. These deaths occurred chiefly at the Cranston institutions, and in the Butler hospital. One death occurred in Bristol county, and two in Kent county.

Sex.-There were 21 male and 22 female decedents.

Parentage. The number of American decedents from insanity was 24, and of foreign parentage 19.
