The mean height of this group of children is 131.5 cm., about l.6 cm. higher than the
average height. Setting out the table on a squared diagram of which each square horizontally represents
a height of one centimetre, and each square vertically represents two scholars, marking the girls off
above the central horizontal line of each standard and the boys similarly downwards diagram is
obtained. The mean height being represented by the vertical white line on this diagram (Diag. 2), a very
good idea of the distribution of children of this age group is obtained; the 12 per cent. dullards are also
seen to be nearly all below the mean height, whilst the two or three per cent. exceptionally clever or
precocious children are generally above the mean.
A similar distribution of the other age groups shows that at any given age the taller children
are found in the higher standards. Apparently mental efficiency, as measured by educational progress
in school, is associated with physical efficiency as determined by growth. This is in accord with the
facts noted by Dr. Porter in his measurements of St. Louis children, and since confirmed by other
investigators.

Table: The distribution of 4164 of the girls of series B is given at each year of age in the various standards.
