Males. total deaths senescent deaths — — — — — — . — . anticipated deaths side of this distribution has been drawn in (broken line in the figures) to exactly mirror the right-hand side. It is thus assumed (unlike Clarke) that the biometric distribution of lifespans is symmetrical. When the deaths of this left-hand side of the distribution are subtracted from the main curve of deaths the residual (of "anticipated" deaths) tails off (by a broken line in Fig. 3) to zero at the peak of the senescent deaths. In effect it is assumed in Fig. 3 that no deaths before.
