When the subject of this paper was suggested to me, I realized that a big task would be involved, but the prospect of obtaining interesting results, combined with the fact that a mortality table applicable to such data would possibly prove of material assistance to Actuaries, emboldened me to proceed with the Investigation.

The Managers of the five large Banking Institutions were approached, and after discussing the matter with them, I was able to proceed with the certain knowledge that the clerical work involved in supplying the data would be carried out by their respective staffs. A circular letter addressed to the Insurance Companies met with an equally sympathetic response, and I was thereby able to receive the cards with the majority of the work, as regards the tabulations of the data, already done. I should like to take this opportunity of tendering my sincere appreciation of the help so readily given by the officials of the Banks and Insurance Companies, not only for allowing me to make use of the data they had available, but also for their assistance in the clerical work involved in tabulation.
