As with strength of grip, so with endurance as measured by the ergograph; boys surpass girls at all ages, and this differentiation becomes very marked after the age of fourteen, after which age girls increase in strength and endurance but very slightly, while after fourteen boys acquire almost exactly half of the total power in these two features which they acquire in the first twenty years of life.
Perhaps the time will come when science and commerce will supply every tintype photographer with an ergograph and the knowledge to use it.
Then we shall hear at summer resorts and fairs, "Your ergograph on a postal card, three for a quarter."
We can step inside, harness our middle finger to the ergograph, lift it up and down forty-five times in ninety seconds, and lo!
The annual report of a board of health should give as clear a picture of a community's health during the past week or past quarter as the ergograph gives of the pupils mentioned on page 126.
If the arm lifts the weight of an ergograph until the will cannot overcome the fatigue, the mere seeing of the movement carried out by others whips the motor centers to new efficiency.
The one scientific instrument it seemed possible to use was an ergograph, a complicated and expensive instrument kindly lent to us from the physiological laboratory of the University of Chicago.
It now relies on purely psychological tests for its researches, and although it does not exclude the methods adopted in the laboratory, and the use of such accurate and trustworthy instruments as the esthesiometer and the ergograph, the school itself has become the chief field of experiment.
This has been clearly determined, for instance, by Féré, in the course of a long and elaborate series of experiments dealing with the various influences that modify work as measured by Mosso's ergograph.
Féré has shown that the slight stimulus to the skin furnished by placing a piece of metal on the arm or elsewhere suffices to increase the output of work with the ergograph.
