l, and a firm, even tread cannot be expected.

The compression of the scalp by a tight-fitting hat interferes with the
local circulation, and may cause headaches, neuralgia, or baldness, the
nutrition of the hair-follicles being diminished by the impaired
circulation. The compression of the chest and abdomen by a tight belt and
various binders interferes with the action of the diaphragm,--the most
important muscle of respiration.

253. Miscellaneous Hints on the Use of Clothing. Children and old
people are less able to resist the extreme changes of temperature than are
adults of an average age. Special care should be taken to provide children
with woolen underclothing, and to keep them warm and in well-ventilated
rooms. Neither the chest nor limbs of young children should be unduly
exposed, as is often done, to the cold blasts of winter or the fickle
weather of early spring. Very young children should not be taken out in
extremely cold weather, unless quite warmly clad and able to run about.
The absurd notion is often entertained that children should be hardened by
exposure to the cold. Judicious "hardening" means ample exposure of
well-fed and well-clothed children. Exposure of children not thus cared
for is simple cruelty. The many sicknesses of children, especially
diseases of the throat and lungs, may often be traced directly to gross
carelessness, ignorance, or neglect with reference to undue exposure. The
delicate feet of children should not be injured by wearing ill-fitting or
clumsy boots or shoes. Many deformities of the feet, which cause much
vexation and trouble in after years, are acquired in early life.

No one should sleep in any of the clothes worn during the day, not even in
the same underclothing. All bed clothing should be properly aired, by free
exposure to the light and air every morning. Never wear wet or damp
clothing one moment longer than necessary. After it is removed rub the
body thoroughly, put on at once dry, warm clothing, and then exercise
vigorously for a few minutes, until a genial glow is felt. Neglect of
these precautions often results in rheumatism, neuralgia, and diseases of
the chest, especially among delicate people and young women.

Pupils should not be allowed to sit in the schoolroom with any outer
garments on. A person who has become heated in a warm room should not
expose himself to cold without extra clothing. We must not be in a hurry
to put on heavy clothes for winter, but
