Pastrycook and the vendor of portable provisions, with their wares of questionable character consumed not at meal times, but at irregular hours. Many an unhappy dyspeptic owes his complaint to a confirmed habit of taking such, or indeed any food in the intervals between regular meals, when the stomach ought to be at rest.
After this period arise the temptations to drink, among the youth of all classes, whether at beerhouse, tavern, or club. For it has been taught in the bosom of the family, by the father's example and by the mother's precept, that wine, beer, and spirits are useful, nay, necessary to health, even for young persons, and that they augment or sustain the strength. And the lessons thus inculcated and too well learned have proved to be the steps which lead to wider experience in the pursuit of health and strength by larger use of the same means. Under such circumstances it often happens, as the youth grows up, that a flagging appetite or a failing digestion habitually demands a dram before or between meals, and that these latter are regarded rather as occasions to indulge in variety of liquor than as repasts for nourishing the body. It is not surprising, with such training, that the true object of both eating and drinking is entirely lost sight of. The gratification of acquired tastes usurps the function of that zest which healthy appetite produces; and the intention that food should be adapted to the physical needs of the body and the healthy action of the mind is forgotten altogether. So it often comes to pass that at middle age, when man finds himself in the full current of life's occupations, struggling for pre - eminence with his fellows, indigestion has become persistent in some of its numerous forms, shortens his "staying power," or impairs his judgment or temper. And, besides all this, how apparent it is that few causes are more potent than an incompetent stomach to engender habits of selfishness and egotism. A constant care to provide little personal wants of various kinds, thus rendered necessary, developes the growth of these sentiments, and they influence the man's whole character in consequence. On the other hand, the poor man, advancing in years, shows signs of damage to his constitution from continuous toil with inadequate food, the supply of which is often diminished by his expenditure for beer, which, although not seldom noxious, he regards as the elixir of life, never to be missed when fair occasion for obtaining it is offered. Many of this class are prematurely crippled by articular disease, etc., and become permanent inmates of the parish workhouse or infirmary. It must be obvious to every one how much more of detail might be added to fill in the outlines of this little sketch. It is designed rather to be suggestive than complete, and thus it amply suffices for my purpose; other illustrations will occur to any observer who cares to pursue the subject further.
