The introduction of French cookery in every part of England amongst the wealthy will render attention to dietetic rules still more important than in former days; although Dean Swift, in his time, observed, "That modern epicurism had become so prevalent, that the world must be encompassed, before a washerwoman can sit down to breakfast." INFLUENCE OF IMAGINATION. Innumerable are the diseases that arise from our busy fancy. We are all subject to the tyrannic sway of imagination's empire. Under this mighty influence man displays energies which lead him boldly to dare danger and complicated sufferings, or he is reduced to the most degraded state of miserable despondency. These diseases are the more fearful, since they rarely yield to physical aid, and it is seldom that moral influence is sufficiently persuasive to combat their inveteracy. It is idle to tell the timid hypochondriac that he is not ill; the mere circumstance of his believing himself sick, constitutes a serious disorder. His constant apprehensions derange his functions until an organic affection arises. The patient who fancies that he labours under an affection of the heart disturbs the circulation, which is ever influenced by our moral emotions, till at last this disturbance occasions the very malady which he dreaded. These aberrations of the mind arise from various causes,--mental emotions, constitution, climate, diet, hereditary disposition, education. Tertullian called philosophy and medicine twin sisters; both may become powerful agents in controlling our imagination.
