to allow a space at the bottom of the tub which will be 

 free for a running stream of hot water. Lie down on 

 this slat bottom, cover the tub with heavy blankets, 

 and you will have as good a vapor bath as need be 

 given. A Swedish shampoo, or a soap and water bath, 

 or scouring the skin off with a brisk ''salt glow," — 

 any or all of these ways are good for getting up a 

 healthy action of the skin. 



Next endeavor to make the lungs work so vigorously 

 as to increase the supply of oxygen. A person walking 

 at the rate of three miles an hour breathes three times 

 as much air as one who is sitting still ; and one walking 

 at the rate of four miles an hour, breathes five times 

 as much as one sitting still. When sitting, one breathes 

 only about twenty cubic inches— about two-thirds of 

 a pint— at each inhalation, the furnace door of the 

 body being almost closed; but as just noted, even 

 moderate walking triples the capacity for taking in air. 

 With every breath, we throw off a certain amount of 

 impurities; at the four-miles-an-hour pace we may not 

 throw off five times as much waste matter as when sit- 

 ting still, but we will api)roximate that amount, per- 

 haps about four times as much. Another advantage 

 in deep breathing is that the oxygen taken into the 

 lungs goes into every nook and cranny, and gets along- 

 side every nerve and fiber of the body,— everywhere 

 this clogging material is lodged,— and carries it out. 

 It is a great house cleaner; it sweeps down the cob- 

 webs, and shakes the curtains. That is why the skin 

 looks clearer and fresher. Let a person whose skin 

 is dingj^, dirty, and sallow, go out of doors and take 

 regular and vigorous exercise. The fresh supply of 

 oxygen thus gained will very soon tell upon the appear- 

 ance of the skin.
