    There is some variation in the percentage alive at three years for the different countries, but this variation is not so great as to destroy the value of the mean figure for the whole series, viz., 39°9 per cent. by method B. If the two smallest series, those for France and for ‘‘ Other Countries,’ be excluded from the calculation the result is very little altered, the new figure obtained by method B being 40°7 per cent. (cf. Table 8c). As already noted this figure corresponds closely with that obtained by the survivorship method. (c) In relation to the type of operation.—Considering now the fate of the patients according to the type of radical operation which they underwent, it is found that the figures for the perineal and sacral operations are large enough to enable the two sexes to be considered separately but that in the case of the combined operation this is not SO. That the samples submitted to the three different types of opera- tion are comparable as regards age and sex distribution is shewn in Table 33, Appendix III, where will also be found the figures from which Tables 10 11, and 12 were calculated. The samples are also comparable as regards the position of the growth (7.e. high, middle or low). It is true that the proportion of high growths is greater for the sacral operation than for the perineal, but this difference is believed to be insufficient to affect the comparability of the figures. The figures in brackets in the tables are the probable errors. TABLE 10. Expected numbers of survivors after Perineal Operation. Survivors (Method B.)
