declare the brain superior
to the stomach in power, health and function; but in the long
accounting, all such temporary superiorities are wiped out. So with men
and women, seeming advantages for either are gained only at the expense
of the common life; and in the last analysis, each finds his individual
value only in the common life of the unit.

Let us try then to see what the special characteristics of women are,
ignoring as far as possible the accidental variations of individuals,
and the temporary advantages or disadvantages due to economic or
ideational forces, and all assertions of what would be if things were
not as they are.

While the whole matter of sex differences is in a state of unsettlement,
it seems very certain that males are more active and more variable than
females. This superabundant vitality appears in the males of the higher
animals in secondary sex characteristics, such as more abundant and
unnecessary hair and feathers, tusks, spurs, antlers, wattles, brilliant
colors and scent pouches. It also appears in mating calls, songs, and
general carriage of the body. Correspondingly, the female is smaller,
duller colored, and less immediately attractive than the male.

All the studies that have been made on men and women, also confirm our
ordinary observation that men are taller, heavier, stronger and more
active than women, and this holds true in all stages of civilization,
wherever tests have been made. In strength, rapidity of movement, and
rate of fatigue Miss Thompson's studies[2] show that men have a very
decided advantage over women. Thus in strength tests, the men in Yale
have double the power of women in Oberlin;[3] while our college athletic
records place men far ahead of women in all events requiring strength
and endurance.

The differences in structure between men and women are such as to
correspond with the functional differences just stated. A woman's bones
are smaller in proportion to her size, than are those of a man. The body
is longer, the hips broader, and the abdomen more prominent. Relatively
to the length of the body, the arms, legs, feet and hands are shorter
than in men, the lower leg and arm are shorter in proportion to the
upper leg and arm. Man has the long levers and the active frame. One has
