Abstract
After the publication of the volume of statistics of the data derived from the Continuous Mortality Investigation 1924–29, experiments were made by the author in fitting the curves developed by Perks in 1931 (J.I.A. LXIII, 12) to various sections of the data. The experiments were later extended to include the data for the Light and Heavy tables and the experience for the period 1924–38. Although these experiments are now mainly of historical interest they represent useful material for research in testing and otherwise and, together with the results of some other published and unpublished graduations, they form the background of this paper.Keywords
