to subside and the strength to improve where they had just seen it fast giving way under a full diet. Appetite, it ought to be observed, may, like other sensations, be educated or trained to considerable deviations from the ordinary standard of quantity and quality--and this obviously for the purpose of enabling man to live in different climates and under different circumstances, and avoid being fixed down to one spot and to one occupation. In civilized life, however, we are accustomed to take undue advantage of this capability, by training the appetite to desire a greater quantity of food than what the wants of the system require, and stimulating its cravings by a system of cookery little in harmony with the intentions of Nature. But this is evidently an abuse, and no argument whatever against the sufficiency of its _natural_ indications to lead us right. But the most common source of the errors into which we are apt to fall in taking appetite as our only guide, is unquestionably the _confounding of appetite with taste_, and continuing to eat for the gratification of the latter long after the former is satisfied; just as the dog already mentioned ate till the œsophagus was distended, although it did not experience the slightest sensation of hunger.[11] In fact, the whole science of a skilful cook is expended in producing this _willing_ mistake on our part; and he is considered decidedly the best _artiste_ whose dishes shall recommend themselves most irresistibly to the callous palate of the gourmand, and excite on it such a sensation as shall at least remind him of the enviable excellence of a natural appetite. If we were willing to limit the office of taste to its proper sphere and to cease eating when appetite expressed content, indigestion would be a much rarer occurrence in civilized communities than it is observed to be.
