of conducting heat from the system in consequence, is increased.
The residual matter with which the clothing is coated is brought in
contact with the skin, which causes irritation, and not unfrequently
re-absorption of the elements, thrown off from the system through this
avenue. Hence warmth, cleanliness, and health require that the
clothing, particularly the garments worn next to the skin, should be
frequently and thoroughly washed. This should not be forgotten in
regard to children, for their blood circulates with greater rapidity
than that of adults, and a proportionably greater amount of waste
matter is thrown off from their systems.

681. _The under-garments worn during the day should not be worn at
night, or the reverse._ When under-garments are worn several
successive days or nights, they should not be put in drawers, or hung
up in a close closet, as soon as taken from the body, but should be
exposed to a current of air.

682. _Occupied beds should be thoroughly aired in the morning._ The
excretions from the skin are most abundant during the hours of
sleep; and if the sheets and blankets, together with the bed, are
not aired every morning, by being so arranged that both surfaces
may be exposed to the air, the materials eliminated from the skin will
be retained in the meshes of the bed-clothing, and may be conveyed
into the system of the next occupant, by absorption. Oftentimes
diseases of a disagreeable nature are contracted in this way. This
fact should be instilled into every mother's and daughter's mind.

_Observation._ Bed-linen should not be put on a bed when it is not
sufficiently dried, or contains moisture from the excretions of the
skin, nor should beds or bedding be slept in, that have remained in a
damp room that has not been occupied for many weeks, unless the
dampness is removed from the bed-linen by a warming-pan, or in some
other way.

683. _Changes of dress, from thick to thin, should always be made in
the morning._ At this time the vital powers are usually in full play.
Many a young lady has laid the foundation of a fatal disease, by
disregarding this rule, in exchanging the thick dress, with woollen
stockings, for the flimsy dress and hose of silk or cotton, which are
considered suitable for the ball-room or party. Sudden changes in
wearing-apparel, as well as in food and general habits, are attended
with hazard; and this is proportionate to the weakness or exhaustion
of the system when t
