As this recreation is actually conducted, it does not tend to produce health of body or mind, but directly the contrary. If young and old went out to dance together, in the open air, as the French peasants do, it would be a very different sort of amusement, from that which is witnessed, in a room, furnished with many lights, and filled with guests, both expending the healthful part of the atmosphere, where the young collect, in their tightest dresses, to protract, for several hours, a kind of physical exertion, which is not habitual to them. During this process, the blood is made to circulate more swiftly than ordinary, in circumstances where it is less perfectly oxygenized than health requires; the pores of the skin are excited by heat and exercise; the stomach is loaded with indigestible articles, and the quiet, needful to digestion, withheld; the diversion is protracted beyond the usual hour for repose; and then, when the skin is made the most highly susceptible to damps and miasms, the company pass from a warm room to the cold night-air. It is probable, that no single amusement can be pointed out, combining so many injurious particulars, as this, which is so often defended as a healthful one. Even if parents, who train their children to dance, can keep them from public balls, (which is seldom the case,) dancing in private parlors is subject to nearly all the same mischievous influences. As to the claim of social benefits,--when a dancing-party occupies the parlors, and the music begins, most of the conversation ceases; while the young prepare themselves for future sickness, and the old look smilingly on. As to the claim for ease and grace of manners,--all that is gained, by this practice, can be better secured, by Calisthenics, which, in all its parts, embraces a much more perfect system, both of healthful exercise, graceful movement, and pleasing carriage.
