THE YOUTHS CABINET. dation of Mr. Gilbert, the late President of the Royal Society. The manner in which he made the acquaintance of this gentleman is as curious as it was import- ant to his future interests. Mr. Gilbert’s attention was attracted to the future philosopher, as he was care- lessly swinging over the gate of Mr. Bor- lase’s house, by the humorous contortions into which he threw his features. Davy, when a boy, possessed a countenance which, even in its natural state, was far from comely, while his round shoulders, inharmonious voice, and insignificant man- ner, were calculated to produce anything rather than a favorable impression; in after years, he was what might be called good-looking. A person walking with Mr. Gilbert on this occasion, observed that the extraordinary looking boy in question was young Davy, the carver’s son, who, he added, was said to be fond of making chemical experiments. “ Chemical ex- periments!” exclaimed Mr, Gilbert, with much surprise; “if that be the case, I must have some conversation with him,” This interview gave ample evidence of the boy’s singular genius, and ended in an offer of the use of Mr. Gilbert’s library to young Humphrey, and any other assist- ance he might require, in pursuing his studies. The delight which Davy expressed on first visiting a laboratory, is said to have been beyond all description ; and on being shown an air-pump, he worked its piston, exhausted the receiver, and opened its valves, with the simplicity and joy of a child engaged in the examination of a new and favorite toy. And here we must leave Sir Humphrey Davy, on his very entrance into the scene of his future labors. How famous he be- 341 came as a chemist and philosopher, is generally known, as well as his elevation to knighthood and to the presidency of the Royal Society. His early poetry shows that he could have become equally distinguished in this art, if he had devoted his faculties to its culture, It is no doubt true that in any pursuit he would have excelled ; for enthusiasm, energy and per- severance are always sure of success.— Boys’ and Girls’ Miscellany. —_————_ Necessity of Sleep. orang is so hurtful both to the mind and body as want of sleep. Deprived of the necessary portion, the person gets wan, emaciated and listless, and very soon falls into bad health; the spirit becomes entirely broken, and the fire of even the most ardent dis- positions is quenched. Nor is this law peculiar to the human race, for it operates with similar power upon the lower ani- mals, and deprives them of much of their natural ferocity. An illustration of this fact is offered in the taming of wild ele- phants. These animals, when first caught, are studiously prevented from sleeping ; in consequence of which, they become, in a few days, comparatively mild and harm- less, Restlessness, when long protracted, may terminate in delirium, or confirmed insanity ; and, in many diseases, 1 is the most obstinate symptom we have tostrug- gle against. By it alone, alll the existing bad symptoms are aggravated ; and as soon as we can succeed in overcoming it, everything disagreeable and dangerous frequently wears away, and the person is- restored to health.—Philosophy of Sleep..
