foot in non-conducting substance is essential. Who neglects this
precaution is guilty of a grievous error, and who helps the poor to
clothe effectively does more for them than can readily be conceived
without careful attention to the subject we have discussed.

2. In sitting-rooms and in bedrooms it is equally essential to
maintain an equable temperature; a fire in a bedroom is of first value
at this season. The fire sustains the external warmth, encourages
ventilation, and gives health not less than comfort.

3. In going from a warm into a cold atmosphere, in breasting the wave
of low temperature, no one can harm by starting forth thoroughly warm.
But in returning from the cold into the warm the act should always be
accomplished gradually. This important rule may readily be carried in
mind by connecting it with the fact that the only safe mode of curing
a frozen part is to rub it with ice, so as to restore the temperature
slowly.

4. The wave of low temperature requires to be met by good, nutritious,
warm food. Heat-forming foods, such as bread, sugar, butter, oatmeal
porridge, and potatoes, are of special use now. It would be against
science and instinct alike to omit such foods when the body requires
heat.

5. It is an entire mistake to suppose that the wave of cold is
neutralized in any sense by the use of alcoholics. When a glass of hot
brandy and water warms the cold man, the credit belongs to the hot
water, and any discredit that may follow to the brandy. So far from
