In the morning scrape the tongue with a strip of whalebone, as before mentioned; brush the teeth with a good stiff clean tooth-brush, up and down, but not across; note this latter proposition, there is reason for it. By perpendicular brushing the bristles or hairs get in between the teeth, where much sediment is left, and the gums are not made sore. This is the best method also to prevent tartar forming. _Gargle_ the throat with clean water three or four times; then, if you have it at hand, drink about three swallows of cool filtered water; if not near go thirsty until it is. Never take a drink of water, whether you be sick or well, without first gargling the throat with at least one swallow and spitting it out. Do you think _filtering_ of reservoir or general city water is necessary? If not, then make a microscopic examination, and any skepticism will be entirely removed. It is a prominent fact in science to-day that almost all diseases and troubles are started or promulgated by microbes and bacilli. There are often enough of these in one swallow of water to poison a whole family. Then take a moist towel and apply it to every part of your body; follow this with a vigorous rubbing with a dry towel. A sponge bath is recommended by many physicians. This is all right for the first time, but from that on the sponge begins to get foul, not from necessity, but because not one person in fifty will wash and thoroughly _dry_ the _sponge_. In any other case it is a disease breeder. Perforated with so many cells and passages, intricate and numberless, it is not surprising that it should be the residence of much that is dangerous. During the time of your bath you should close the windows of your room to exclude the cold draughts--in any part of the country where the atmosphere moves over two miles per hour--but not the sun. After this lower or raise your window to the height or level of the eyes, and proceed to enjoy a breathing exercise. This is done by first exhausting all the air from the lungs through the mouth, then inhale, slowly, through the nasal organs to the full capacity of the lungs. Do this _three_ times or more each morning. If your lungs are not too weak, tap with your fingers on your chest while it is inflated. This will tend to develop your capacity of breathing wonderfully. The gentle percussion thus effected is quite exhilarating. Practice yourself also in _holding_ your _breath_ for a prolonged interval, but always draw in air through your nostrils; they strain out all impurities.
