igorous rubbing, is undoubtedly healthful for a
large number of people. The cold bath is often used by physicians in the
treatment of diseases of low vitality. Many persons however, are
unpleasantly affected by bathing in water of a temperature much below
that of the body; particularly is this true of women, and the like may be
said of thin and nervous persons of the other sex. It is claimed by the
advocates of the cold bath that those who practice this procedure daily
are practically immune from colds, but this, certainly, is not always
true; on the contrary the writer has seen instances where the cold bath
has unquestionably led to chronic nasal catarrh, with increased tendency
to inflammatory conditions of the air passages. It is also the case that
baths of this description tend in some persons to prevent a normal
accumulation of fat beneath the skin, and keep individuals of this kind
unnaturally lean.

The warm bath is perhaps, on the whole, more popular than the cold, since
it is preferred usually by children and women, and is practiced by a
considerable proportion of adult males. It is unquestionably somewhat
enervating, and at best fails entirely to give the agreeable stimulation
experienced by those who take a cold plunge. It is, however, to be
preferred in those instances where cold water produces disagreeable
effects, and if the bath be not too long continued it is followed by no
ill results. Persons who become lean under cold baths not uncommonly take
on flesh when they begin to use warm ones. It is unquestionably true that
the latter is to be preferred in hot climates.

The sea bath is invigorating not only from the water being cool, but as a
consequence of the pleasurable excitement with which it is attended. Its
greatest disadvantage lies in the fact that there is a tendency to overdo
it, many persons remaining in the water for hours. Ten or fifteen minutes
is as long as the average person should indulge in sea-bathing, and it is
a question if even those who are young and vigorous should remain in the
water longer than half an hour.

Bathing of any kind should be indulged in before meals, the best time
being before breakfast in the morning.

_Care of the Teeth._--Nothing in connection with the subject of personal
hygiene is of more importance than keeping the teeth properly cleansed.
The fact is not generally appreciated that sound teeth stand in a most
intimate relationship with good health, and that d
