Whenever you feel the slightest touch of sore throat, examine it at the
glass, and if there be any redness, do it over with your camel's-hair
pencil dipped in a mixture of glycerine two parts and tincture of iron
one part.

As for tic, you protect yourself against cold and damp, but you ought
also to take an occasional tonic, and there is nothing I know better
than the citrate of iron and quinine. If, however, this medicine should
produce a disagreeable feeling of fulness in the head, it had better be
avoided and some other tonic substituted. Well, there is cod-liver oil
in conjunction with the extract of malt. This is the only form in which
cod-liver oil can be taken by many.

I should mention that an occasional aperient pill will do good, but that
the habit of taking medicine of this kind as a regular thing should be
avoided.

In cold weather the feet should be kept very comfortable, but you must
avoid sitting too much by the fire. I have already said that sudden
atmospheric changes are dangerous, but girls often manufacture these
changes for themselves, quite independent of the weather, by keeping
themselves too warm indoors and hugging the fire too much.

In cold weather the food should be more nourishing, and soups are good
for the health. Soups should be avoided when the weather changes to
warm.

Sugar, sweets, puddings, and fatty foods are all good in cold, bleak
weather, but in summer these do harm, if used to any great extent, by
heating the blood.
