    comparing Table XI with Table XII, and is persistent for each group of entry-ages and for each section of the Tables for the first ten years of assurance, with the single exception of ages at entry below 38 under whole-life assurances. The exception is noteworthy, as the excess mortality is considerable, and coincides with the results of previous experiences under whole-life assur- ances on female lives. It may possibly point to the fact that under endowment assurances the spinsters are in greater proportion than the married women. High Mortality. Returning to the high rate of mortality during the Years of^arIy first five years of assurance, it will be seen that whilst Assurance. 1 . the endowment assurance rates are but little in excess of 0[BM], the whole-life are considerably in excess of 0[M]. From Tables IX and X it will be seen that this excess in both whole-life and endowment assurances is at its maximum in year of assurance 0, and that it decreases fairly rapidly with the duration. In regard to the year of assurance 0, it is to be remarked that the OlEM1 experience also shows a relatively heavy rate of mortality at this period as compared with 0[M1. This raises a doubt as to whether, from some unexplained cause, the 0[MJ may not give too small a value for gM+0, and, consequently, whether it is a suitable standard at this point. After making all allowances for this possibility, however, it would still appear that the mortality experienced in the early years of assurance was heavy. The excess is greatest for the younger ages at entry. Combining these facts, we may say that the effect of a definite family history of tuberculosis shows itself mainly in the younger ages at entry and the early years of assurance. Passing from the consideration of Group A as a Sectional whole, we consider next the three main sections of which it is composed. These are (a) Lineals, (/3), Lineals plus Collaterals and (<y) Collaterals. The same general arrangement of the Tables has been adopted as for the combined results, except that owing to paucity of data, the detailed facts for each of the first ten years of assurance are shown only for endowment assurances on male lives. It may be well to point out here that the terms ‘'lineal and “collateral” are used throughout this Paper in the special and restricted sense indicated in the Table of Classification.
