matters; let each have fresh animal food every day, and what is the consequence? Our little pale friend brightens up amazingly; there comes a tinge of red in the cheek, the puffiness is gone, and the flesh has become more solid--he is more active and sprightly; but our other little fellow is evidently not benefited; the healthy rose hue looks more like a feverish flush, and suspicious spots, that will soon break out into little pimples or small boils, are perhaps showing themselves. This will never do, so we keep the little fair one to his beef and mutton, and reduce his companion, who soon shows the benefit of the change, to his milk-puddings and vegetables, and give him his treat of meat only twice or thrice a week. This one example--we might give many more--will serve to show how many considerations are involved in this first department of physical training--the management of the food: how that which gives health and strength to one will be too little for another, and _vice versâ_. Then, again, we might show how the variation of climate, even such as takes place between winter and summer in our land, requires variation in the amount and kind of food; how also this should be influenced by exercise. These minutiæ cannot be separately discussed in the compass of a short paper; but the information is such that no intelligent man, either for his own sake or that of others, should be entirely unfurnished with. As a general rule, let it be kept in mind, especially in the case of the young and growing, that the habitual food ought to be calculated to yield the requisite nourishment for every portion of the frame; that it ought, while adapted to the constitution, to be sufficient in quantity and quality. Rarely, indeed, if food be wholesome, and at the same time not calculated to tempt the appetite artificially, can it be necessary, or even right, to stint its allowance to young people? Lastly, as far as possible, the application of a well-directed cookery, by which the digestibility of food is improved, ought not to be lost sight of, as an important element in the physical training of the young, or of the physical preservation of the adult.
