the body results from the equal and harmonious cultivation of all the
mental powers. The perfect development and health of the physical organs
is therefore essential to the happiness of mankind. But, before health
can be insured the nature and general functions of the physical system
must be understood. This being done, the question naturally arises: _How
can health be best maintained and longevity secured?_

INFLUENCE OF FOOD. We have previously noticed the effects which food,
exercise, and other hygienic agencies, have upon digestion, circulation,

upon the health of the generative organs. Excessive stimulation excites
the sexual passions. For this reason, children should not be
immoderately indulged in highly seasoned foods. Those persons who have
great muscular vigor are endowed with violent passions, and unless
restrained by moral considerations, are very likely to be overcome by
