a. =The Bath for Cleanliness.=--Little need be said regarding the bath
for cleanliness except that it should be taken at least once in a week
during the colder portion of the year and perhaps as frequently as
once a day during that portion of the year when there is free
perspiration.

Where one is bathing for cleanliness he may well use soap and warm
water over the whole surface of the body. If he takes this bath just
before retiring, it is not necessary to take a cold shower or sponge
at the end of the bath. If, however, one takes a warm soap bath in the
morning the relaxing effect of the bath upon the skin makes it
necessary to take a cold shower or a cold sponge after the warm bath
in order to secure the tonic effect upon the skin and fortify one
against catching cold.

During the hot weather when one may bathe daily for cleanliness he
should guard against an excessive use of soap, as a daily soap bath
may have a tendency to remove the oils from the skin so completely as
to make the skin rough. With the daily bath for cleanliness it is
possible that warm water and soap need not be used more frequently
than once or twice a week and that a laving of the whole surface with
cold water followed by a vigorous rub down with a coarse towel may
serve the double purpose of insuring absolute cleanliness, and at the
same time serving as a skin tonic.

In this connection the author would emphasize the importance of
insuring absolute cleanliness of the sexual apparatus. In primeval
conditions less attention was necessary as these organs were more or
less exposed, but the present method of dress is such as to permit the
accumulation of the skin secretions. While these may in part be
removed by the friction against the clothing, it is advisable to wash
the external genitals and all neighboring surfaces as a regular part
of the daily toilet.

b. =The Tonic Bath.=--In warm weather when one takes a daily bath to
insure cleanliness, at least five of these baths each week may be in
cold water, sufficiently cold to secure the tonic effect as described
above. In cold weather, when one takes not more than one or two warm
soap baths a week, the cold tonic bath can be made to serve a most
important purpose in the hygiene.

Some have followed the custom of immersing the body completely in a
tub of cold water. This method of taking the cold bath is not to be
recommended except for those who are in the most robust health, and in
these
