In the first place, you mustn't catch it. If you keep your
extremities warm by substantial flannels, exercise much in the open
air, eat the right quantity of plain food, sleep with open windows
and shun hot drinks, you will avoid colds.
But, suppose you have a cold? Eat nothing but a piece of toast;
drink freely of cold water; walk twice a day till you are in a
gentle perspiration, and go to bed early. These rules observed, and
colds, which produce so much mischief, would be shorn of their power
of harm.
