PREFACE.

IN the Preface to “The Mortality Experience of Life Assurance Companies, collected by the Institute of Actuaries,” published in May, 1869, it was stated, “The preparation of monetary and other Tables for official purposes is a work involving so much time, labour, and expense, that the Council of the Institute of Actuaries have decided not further to delay the publication of the original facts, on which they will have to be computed.”

The liberality of several Life Assurance Companies promptly relieved the Council from all anxiety in regard to the expense attending the completion of so extensive a work. Their further contributions, in answer to a circular issued in June, 1869, amounted to £605, making the total Fund collected £1142. 55. A List of the contributing Offices is appended to this Preface.

As a preliminary to the determination of the classes of monetary Tables to be computed, it was considered important

1. That the Tables of Mortality deduced directly from the

Observations should be graduated in such a manner as to preserve, to the utmost possible degree consistent with their practical use, all the original features of the Observations.
