errified by the immersion,
and every precaution should be taken to prevent this. The healthy and
robust boy, too, should early be taught to swim, whenever this is
practicable, for it is attended with the most beneficial effects; it is
a most invigorating exercise, and the cold bath thus becomes doubly
serviceable.

PLAN TO BE PURSUED WITH THE DELICATE AND STRUMOUS.--If a child is of a
delicate and strumous constitution, the cold bath during the summer
is one of the best tonics that can be employed; and if living on the
coast, sea-bathing will be found of singular benefit. The effects,
however, of sea-bathing upon such a constitution must be particularly
watched, for unless it is succeeded by a glow,--a feeling of increased
strength,--and a keen appetite, it will do no good, and ought at once
to be abandoned for the warm or tepid bath. The opinion that warm baths
generally relax and weaken, is erroneous; for in this case, as in all
cases when properly employed, they would give tone and vigour to the
whole system; in fact, the tepid bath is to this child what the cold
bath is to the more robust.

In conclusion: if the bath in any shape cannot from circumstances be
obtained, then cold saltwater sponging must be used daily, and all the
year round, so long as the proper reaction or glow follows its use; but
when this is not the case, and this will generally occur, if the child
is delicate and the weather cold, tepid vinegar and water, or tepid
salt water, must be substituted.

Sect. VI. CLOTHING.

IN INFANCY.--Infants are very susceptible of the impressions of cold; a
proper regard, therefore, to a suitable clothing of the body, is
imperative to their enjoyment of health. Unfortunately, an opinion is
prevalent in society, that the tender child has naturally a great power
of generating heat and resisting cold; and from this popular error has
arisen the most fatal results. This opinion has been much strengthened
by the insidious manner in which cold operates on the frame, the
injurious effects not being always manifest during or immediately after
its application, so that but too frequently the fatal result is traced
to a wrong source, or the infant sinks under the action of an unknown
cause.

The power of generating heat in warm-blooded animals is at its minimum
at birth, and increases successively to adult age; young animals,
instead of being warmer than adults, are generally a degree or two
colder, and part
