[Footnote A:  The expression of the above facts in terms of percentages for each age group was found to be difficult, since failures and not pupils are designated.  But the total failures for each age group are expressed (on p. 36) as percentages of the entire number of subjects taken by these pupils for the semesters in which they failed.  Such percentages increase as the ages rise.  A similar statement of the percentages of failure by semesters will be found on p. 41.]

Table I reads:  the boys had 20 failures and the girls had 19 failures in the first semester and at the age of thirteen; in the second semester, at the age of thirteen, the boys had 2 failures and the girls 6.  For each semester, the first line represents boys, the second line girls.  There is a total of 17,960 failures listed in this table.  In addition to this number there are 1,947 uncompleted grades for the failing non-graduates.  The semesters were frequently completed by such pupils but the records were left incomplete.  Their previous records and their prospects of further partial or complete failure seem to justify an estimate of 55 per cent (1,070) of these uncompleted grades as either tentative or actual but unrecorded failures.  Therefore we virtually have 1,070 other failures belonging to these pupils which are not included in Table I. Accordingly, since the number can only be estimated, the fact that they are not incorporated in that table suggests that the information which it discloses is something less than a full statement of the school failures for these pupils.  In the distribution of the totals for ages, the mode appears plainly at 16, but with an evident skewness toward the upper ages.  The failures for the years 16, 17, and 18, when added together, form 68.1 per cent of the total failures.  If those for 15 years are also included, the result is 86 per cent of the total.  Of the total failures, 65.7 per cent are found in the first two years (11,801 out of the total of 17,960).  But the really striking fact is that 34.3 per cent of the failures occur after the end of the first two years, after 52.2 per cent of the pupils are gone, and with other hundreds leaving in each succeeding semester before even the end of the eighth.  In Table II we have similar facts for the pupils who graduate.
