commonly in use by all persons. Obviously these are the muscles used in walking. Quite a large number of tests had been measured by the Fisher machine, but it was still being studied with a view to possible simplification.

I was asked to try it and to suggest any changes that might improve it. I did so, and handled the weight with such seeming ease that Dr. Anderson asked me whether I would not make a thorough test of my endurance. This I was glad to do.

The Professor Irving Fisher Endurance Testing Machine is weighted to 75 per cent. of the lifting capacity of the subject, ascertained by means of the Kellog Mercurial Dynamometer. The lifting is timed to the beats of a metronome.

When I began, Dr. Anderson cautioned me against attempting too much. I asked him what he considered "too much," and he replied: "For a man of your age, not in training, I should not recommend trying more than fifty lifts." So I began the test, lifting the weight to the beat of the metronome at the rate of about one in two seconds, and had soon reached the fifty mark. "Be careful," repeated Dr. Anderson, "you may not feel that you are overdoing now, but afterwards you may regret it."

But I felt no strain and went on.

When seventy-five had been exceeded, Dr. Anderson called Dr. Born from his desk to take charge of the counting and watching to see that the lifts were fully completed, and ran out into the gymnasium to call the masters of boxing, wrestling, fencing, etc., to witness the test. When they had gathered about the machine, Dr. Anderson said to them, "It looks as if we were going to see a record-breaking." I then asked, "What are the records?" Dr. Anderson replied, "One hundred and seventy-five lifts is the record; only two men have exceeded one hundred; the lowest was thirty-three, and the average so far is eighty-four."

In the meantime I had reached one hundred and fifty lifts, and the interest was centered on the question as to whether I should reach the high record, one hundred and seventy-five.

When one hundred and seventy-five had been reached, Dr. Anderson stepped forward to catch me in case the leg in use in the test should not be able to support me when I stopped and attempted to stand up. But I did not stop lifting the three-hundred-pound weight. I kept right on, and as I progressed to two hundred, two hundred and fifty, three hundred, and finally to double the record, three hundred and fifty lifts, the interest increased progressively.

After adding a few to the three hundred and fifty I stopped, not because I was suffering from fatigue, but because the pounding of the iron collar on the muscles above my knee had made the place so pummelled very sore, as if hit a great number of times with a heavy sledge-hammer. I had doubled the record, and that seemed sufficient for a starter in the competition.
