With very few exceptions these tables are higher for both boys and girls at all ages than those of Professor Hastings though in most cases where there is no difference in the instruments and the mode of taking the measurements, the difference is very slight. His tables are based on more children hut these have the advantage of being based in a large measure upon the same children at different ages. The differences in height and weight which, according to the tables, place eastern children about one year in advance of western in those respects is partly, but perhaps not wholly, accounted for by the fact that our children retained their shoes, while those measured under the direction of Professor Hastings did not. In height sitting the differences are slight, also in breadth of head and girth of head, but in breadth of chest and of waist they are somewhat greater, while in depth of chest the difference is very marked amounting at nearly every age to two or more cm. This can not be accounted for by any difference in clothing or mode of measurement so far as we know. It seems to indicate a marked physiological difference between eastern and western children. Chest expansion and lung capacity correspond pretty well, con- sidering the difficulty of making accurate tests of children who have had little or no practice in controlling the muscles of chest and lungs. The difference of from two to six kilograms in the strength of forearm, as indicated by grip, can not be wholly accounted for by the adjustable dynamometer used by us, for our records are some-
