On the Value of Mr. Gompertz's Formula for the Number Living in Terms of the Mortality according to Age, compared with the Value of a similar Formula published in 1832

Abstract

In the Assurance Magazine (Oct., 1860, and July, 1861) there have appeared two papers written by me to show in what respect the law of human mortality described by Mr. Gompertz in 1825 differs from the law described by me in 1832. In the same papers I have also shown in what respect the formula of Mr. Gompertz, , for the number living in terms of the mortality according to age, differs from my formula for the same purpose, which is , on putting instead of , as assumed by Mr. Gompertz.
