They are very likely also to be inerect, with flat, thin chests, and contracted stomach and abdomen. Now the habit of constantly keeping erect, whether sitting, standing, or walking, combined with this same deep, abdominal breathing, soon tends to expand not only the lower ribs and lower part of the lungs, but the waist as well, so giving the digestive organs more room and freer play. Like the lungs, or any other organ, they do their work best when in no way constrained. Better yet, if the person will also habituate himself, no matter what he is at, whether in motion or sitting still, to not only breathing the lower half of the lungs full, but the whole lungs as well, and at each inspiration hold the air in his chest as long as he comfortably can, he will speedily find a quickened and more vigorous circulation, which will be shown, for instance, by the veins in his hands becoming larger, and the hands themselves growing warmer if the air be cold; he will also feel a mild and agreeable exhilaration such as he has seldom before experienced. Some of these are little things, and for that reason they are the easier to do; but in this business, as in many others, little things often turn the scale. Of two brothers, equally thin, equally over-active, as much alike as possible--if one early formed these simple habits of slow and thorough mastication, deep and full breathing, resting awhile after meals, carrying his body uniformly erect, and sleeping plentifully, and his brother all the while cared for none of these things, it is highly probable that these little attentions would, in a few years, tell very decidedly in favor of him who practised them, and gradually bring to him that greater breadth, depth, and serenity, and the accompanying greater weight of the broad, full, and hearty man. And what about the old people? Take a person of sixty. You don't want him to turn gymnast, surely. No; not to turn gymnast, but to set aside a small portion of each day for taking such body as he or she now has, and making the best of it. But how can that be done? and is it practicable at all for a person sixty years old, or more? Well, let us see what one, not merely sixty, but eighty, and more too, had to say on this point. Shortly after the death of the late William Cullen Bryant, the New York _Evening Post_, of which he had long been editor, published in its semi-weekly issue of June 14th, 1878, the following letter: "MR. BRYANT'S MODE OF LIFE. "The following letter, written by Mr. Bryant several years ago, describing the habits of his life, to which he partly ascribed the wonderful preservation of his physical and mental vigor, will be read with interest now: "'New York, March 30, 1871.
