An establishment at once deserving of the attention of men of feeling, particularly of those who, in cultivating literature, apply themselves to the science of metaphysics and grammar; an establishment extremely interesting to every one, the great difficulties of which mankind had, repeatedly, in the course of ages, endeavoured to encounter, and which had driven to despair all those who had ventured to engage in the undertaking; an establishment, in a word, which produces the happiest effects, and in a most wonderful manner, is the NATIONAL INSTITUTION OF THE DEAF AND DUMB. To the most religious of philanthropists is France indebted for this sublime discovery, and the Abbé SICARD, a pupil of the inventor; the Abbé de l'Epée, has carried it to such a degree of perfection, that it scarcely appears possible to make any further progress in so useful an undertaking. And, in fact, what can be wanting to a species of instruction the object of which is to establish between the deaf and dumb, and the man who hears and speaks, a communication like that established between all men by the knowledge and practice of the same idiom; when the deaf and dumb man, by the help of the education given him, succeeds in decomposing into phrases the longest period; into simple propositions, the most complex phrase; into words, each proposition; into simple words, words the most complex: and when he distinguishes perfectly words derived from primitives; figurative words from proper ones; and when, after having thus decomposed the longest discourse, he recomposes it; when, in short, the deaf and dumb man expresses all his ideas, all his thoughts, and all his affections; when he answers, like men the best-informed, all questions put to him, respecting what he knows through the nature of his intelligence, and respecting what he has learned, either from himself or from him who has enlightened his understanding? What wish remains to be formed, when the deaf and dumb man is enabled to learn by himself a foreign language, when he translates it, and writes it, as well as those of whom it is the mother-tongue? Such is the phenomenon which the Institution of the deaf and dumb presents to the astonishment of Europe, under the direction, or rather under the regeneration of the successor of the celebrated Abbé de l'Epée. His pupils realize every thing that I have just mentioned. They write English and Italian as well as they do French. Nothing equals the justness and precision of their definitions. Nor let it be imagined that they resemble birds repeating the tunes they have learned. Never have they been taught the answer to a question. Their answers are always the effect of their good logic, and of the ideas of objects and of qualities of beings, acquired by a mind which the Institutor has formed from the great art of observation.
