John Wesley was possessed of so great a fund of common sense, and of such remarkable powers of observation, that he became as noted among the common people for his instructions in relation to health and the treatment of disease as for his theological teachings. He even wrote a medical work which, altho it contained many things of which we can not approve, was, nevertheless, in its recognition of rational and natural remedies, more than a century ahead of the times when it was written. Mr. Wesley recognized fully the value of exercise as a means of preserving health. He was always a man of active habits, and declared that he owed his vigor to the fact that when he went up to London to school, his father charged him, in his parting instructions, that he should run three times around Charter House Square every morning before breakfast. This practice he adhered to during his school life, and thus was kept in excellent health. A man recently measured the distance around Charter House Square, and reports it to us to11be 445 yards, or a little more than one-fourth of a mile. Three times around the square would be three-fourths of a mile. To take this exercise would have required from ten to fifteen minutes, according to the rate of speed. If Mr. Wesley ran at a brisk trot he would have so increased his respiration and the action of his heart as to have brought a large amount of air into his lungs and circulated his blood thoroughly to every part of his body. Mr. Wesley’s father must have been a man far advanced in his knowledge of the benefits of exercise for students, or he would not have given his son this wise command.—Journal of Hygiene.
