TREATMENT.--Whatever plays an important part in the etiology of the disease ought to be carefully avoided. The feet must be kept warm under all circumstances, nothing being more injurious to health in general, and to that of the respiratory organs in particular, than cold and moist feet. Shoes and stockings must be kept dry, the latter changed when wet, and of slowly-conducting material. No part of the body must be kept uncovered, and the dresses of children made the particular object of care on the part of the family physician. Linen must not be in immediate contact with the skin, cotton--or, still better in all seasons, wool--being required for the undergarment. At the same time, the hygiene of the skin requires attention. Regular washing or bathing need not be mentioned as a requisite, as it is self-understood. What, however, cannot be insisted upon too much is this, that the skin must get accustomed to cold water. The whole body must be exposed once a day to cold water--washing or bathing--and well rubbed off afterward with a thick towel. Young infants and those who are very susceptible to colds begin with tepid water, the temperature being lowered from day to day. Even children of three or four years enjoy, finally, a morning bath at sixty or sixty-five degrees F. in winter. Such as do not get easily warmed up under the succeeding friction may mix alcohol with the water they use for washing and sponging purposes, in the proportion of 1:5-8. Sea-bathing also makes the skin more enduring, to such an extent that exposure to cold air has no longer any damaging influence. In fact, cold air without wind is easily tolerated even by those who have a tendency to respiratory disorders, while wind and draught must be avoided. From this point of view the change of climate sometimes required for such as suffer from catarrhal laryngitis must be instituted. It is not always necessary to select a very warm climate; undoubtedly, many of the winter resorts are badly selected, for the very reason that they are too warm. On the other hand, great elevations are not advisable. The sudden atmospheric changes and fogs of high mountains are injurious.
