been denied life insurance on account of health disability. This was worth more than millions of money to me; and no one knows how much it will signify to the human family when the knowledge of a truly economic nutrition is attained and established. I was bright awake at daylight the next morning and had the impulse to mount my wheel and see how "fit" I was in consequence of my exertion of the day before. This I did, and rode eighty kilometers (fifty miles) before breaking my fast at nine o'clock. I believe I could have ridden as far that day had the conditions been favourable. My weight, on return to my balances at Brolles, was reduced two kilograms (nearly five pounds), but a generous thirst for a day or two, and a slightly increased appetite put the loss back again inside a week even while riding my wheel daily on the way to Geneva. Since reaching Italy, and abiding in Venice, there have been long periods when no systematic physical exercise has been indulged in. Once, after nearly a year of physical inactivity, I took with me an attendant and made an average of seventy-five miles a day in the mountain districts of southern Germany for observation of increase of food requirement during hard work. Neither muscular soreness, nor muscular fatigue, except the periodical weariness of sleepiness, were experienced as the result of the sudden change from the most restful environment to strenuous activity; and herein lies a physiological question that is far-reaching in its significance. It would seem that Appetite, in its normal condition, assisted in its discrimination by careful mouth-treatment of food, guards the body from excess and keeps it always "in training." The later experience at Yale University under Dr. Anderson and Professor Chittenden showed the same immunity from muscular disability, and has brought the question to good hands for solution. The author has voluminous data relative to his work, but it is not applicable to any other person. Each person is a law unto himself and no two sets of conditions are alike. Treat your food as advised herein and get surprising new experiences for yourselves, is the advice and moral of the story. GENERAL OBSERVATIONS HEALTH, HARMONY AND HAPPINESS Health, Harmony and Happiness are the natural heritage of man. The human body is the most perfect piece of mechanism possible to imagine. The human body is intended to nourish Health, maintain Harmony, and conserve Happiness. * * * * * The body machine is self-building or self-growing, self-lubricating and self-repairing. A simple knowledge, only, is necessary for proper (preventive) care of the body machine. All that Nature requires of man is to supply fuel preferred and, therefore, prescribed by Normal Appetite and to direct the energy generated along alluring lines of usefulness. * * * * *
