material installation this system is financially economic. Personal
faults and shortcomings are constantly pointed out where this work is
best represented, and it has a distinct advantage in inciting an
acquaintance with physiology and inviting the larger fields of medical
knowledge.

D. The fourth gymnastic aim is symmetry and correct proportions.
Anthropometry and average girths and dimensions, strength, etc., of
the parts of the body are first charted in percentile grades; and each
individual is referred to the apparatus and exercises best fitted to
correct weaknesses and subnormalities. The norms here followed are not
the canons of Greek art, but those established by the measurement of
the largest numbers properly grouped by age, weight, height, etc.
Young men are found to differ very widely. Some can lift 1,000 pounds,
and some not 100; some can lift their weight between twenty and forty
times, and some not once; some are most deficient in legs, others in
shoulders, arms, backs, chests. By photography, tape, and scales, each
is interested in his own bodily condition and incited to overcome his
greatest defects; and those best endowed by nature to attain ideal
dimensions and make new records are encouraged along these lines. Thus
this ideal is also largely though not exclusively remedial.

This system can arouse youth to the greatest pitch of zest in watching
their own rapidly multiplying curves of growth in dimensions and
capacities, in plotting curves that record their own increment in
girths, lifts, and other tests, and in observing the effects of sleep,
food, correct and incorrect living upon a system so exquisitely
responsive to all these influences as are the muscles. To learn to
know and grade excellence and defect, to be known for the list of
things one can do and to have a record, or to realize what we lack of
