Madame Patti, who always has been obliged to take the greatest care of herself, gives this warning, which may not be out of place: "Take plenty of exercise, take it in the open air, take it alone, and breathe with the mouth closed. Live on simple food; all the fruit and rare beef you want, very little pastry, a glass of claret for dinner, coffee in moderation, but never a sip of beer, because it thickens the voice and stupefies the senses. Keep regular hours for work, meals, rest, and recreation, and never under any circumstances indulge in the fashionable habit of eating late suppers. If you want to preserve the beauty of face, and the priceless beauty of youth, keep well, keep clean, keep erect, and keep cool." Without being didactic, let me detail to you a few things you should and should not do; and all of which I carry out to the letter:-- Adopt some style of _clothing_ so that even if you change the color the _weight_ will be about the _same_. Wear no overcoat, overshoes, nor gloves; in their place wear a sufficiently heavy suit when it is warm, so as to have enough on when it is cold. By wearing a _chest protector_ fore and aft of the lungs, made of chamois and flannel, over the under-garment and under the shirt, you will never take cold through your lungs. Have good, thick-soled _boots_--and always of the same thickness--and you will not take cold through your feet. Have a _hat_ always of the same weight, and that should be light, with ventilators in the top or sides. If you do not wear your hat at the lunch table, or in your place of business, you will not catch cold in your head. A large list of accessories accompany the above:-- Never sit at your desk or home fireside with the same coat which you use on the street. In its place have one 50 per cent lighter for such occasions and positions. Never _sleep_ in your _under-garments_, nor in any other clothing that you carry during the day. The reason is strong and obvious. Your covering in the course of the day receives all the perspiration and surface deposit of the skin, which amounts to considerable in sixteen hours. This must have a chance to escape or be absorbed by the air. The amount is only increased by wearing the same garments at night. Have a good warm _night-shirt_, and a clean one at least every week. Do not sleep in a room without having the windows down from the top to some extent. If there be six, lower three of them.
