    in altering the form of curves is apparent, as the pitch of the curves between 14 and 14d) does not really represent the rate of growth of the boys examined. The boys measured at 14-6 would have l^een previously measured nearly a year before, and the extra increase put on would in reality ])e distributed over that period. Before applying our various results to estimate the physical progress of individuals, it is necessary to answer the question : How far does the growth of the standard boy of any grade represent the probable growth of the corresponding healthy boy ? In order to obtain an approximate answer I have used exclusively the records belonging to school A. I first selected all the records which I could find, which appeared to cover a sufficient number of the years included in my tables, viz., 124 to 18^. This gave me KH boys, whose records included 1,459 observations in each of the three details examined, an average of slightly over 9 oljservations to each boy, the observations being recorded half-yearly. I next deter- mined what each of these boys’ records became when every detail was expressed in grades. The tables used were constructed from the curves shown in Figs. 4, 5, and f). On examination I found that 1 could classify the growth of the boys somewhat roughly as follows ;— The growth followed that of a standard boy within moderate limits of variation in ... ill per cent, of the boys. There was a steady rise relative to the standard boys through- out the period examined in... 17 ,, „ A similar fall in ... ... 10 ,, „ A period of rise, followed by one of fall, or vice-versd^ in... 18 The variation struck me as distinctly erratic in... ... 9 ,, ,, The remaining 15 per cent, did not strike me as falling into any of these classes ; they would probably belong to the first class, but not within the limits of variation which I allowed.
