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. The change in this country from cold with high winds and perhaps frosts at night to warmth and even scorching heat is often very sudden. Even the delicate are then very apt to throw off their winter or spring clothing. But to do so suddenly is highly injudicious. Girls who are not strong should wear some woollen material all the year round. This should of course be of a lighter texture in summer, but woollen it ought to be, without doubt. It is, I believe, a fact that there are fully as many disagreeable colds caught in summer as in winter, and this can only be owing to the greater recklessness with which people expose themselves to the influence of the weather. During sultry and thundery weather, as it is called, many of the delicate suffer from languor, listlessness, and headache. These symptoms usually go away suddenly when the weather breaks or the storm comes on and rolls over. Exertion in cases of this kind should be avoided, as well as anything like heavy meals. The sufferer is better out of doors than in, and better reclining in a hammock or easy-chair out of a draught than standing or walking about. Hot weather greatly depresses the vital energy, because it usually comes on so suddenly. On very warm days the delicate should avoid the sunshine's glare during the heat of the day. But exercise must be taken if health is to be retained, so in summer even girls that are not strong should get out of bed soon and take a tepid if not cold bath. About half-an-hour after breakfast is the best time for exercise, and again about an hour before sunset, just when the day is cooling down, but before the chill, night air has begun to blow.
