M. HAÜY details to strangers every part of his plan with the most patient and obliging attention. When he had concluded, I could not avoid expressing a wish that the art of instructing the blind in the fullest extent might be speedily introduced among all nations. "After having paid to my country," rejoined M. HAÜY, "the merited homage of my invention, my anxiety to contribute to the relief of the afflicted, wherever they may be found, gives birth to the desire of propagating, as much as possible, an institution which enlightened men and philanthropists have been pleased to recommend to the attention of foreigners and to the esteem of my countrymen, as may be seen by consulting different literary publications from the year 1785 down to the present time, particularly the new French Encyclopædia, at the article _Aveugle_." "I should," added he, "perform a task very agreeable to my feelings in concurring, by my advice and knowledge, to lay in England the foundation of an establishment of a description similar to either of those which I have founded in Paris. One of my pupils in the art of instructing the blind, M. GRANCHER, a member of several learned societies in France, and possessed of my means and method, would voluntarily devote his talents and experience to the success of such an undertaking, to which he is himself strongly attached through philanthropy and zeal for my reputation."--"I am persuaded," interrupted I, "that were the advantages of such an establishment made public in England, it would receive the countenance and support of every friend of human nature."--"It is an unquestionable fact," concluded M. Haüy, "that an institution of fifty blind, well conducted, ought, by their labour, to produce more than would defray its expenses. I have already even tried with success to apply to the English tongue my method of reading, which is so contrived for the French language, that I need not give more than two or three lessons to a blind child, in order to enable him to teach himself to read, without the further help of any master." LETTER XLI. _Paris, December 29, 1801._ Such a crowd of different objects present themselves to my mind, whenever I sit down to write to you, that, frequently as I have visited the Grand French Opera since my arrival here, I have been hesitating whether I should make it the subject of this letter. However, as it is one of the first objects of attraction to a stranger, and the first in a theatrical point of view, I think you cannot be too soon introduced to a knowledge of its allurements. Let us then pass in review the THÉÂTRE DES ARTS ET DE LA REPUBLIQUE.[1] Previously to the revolution, the French opera-house, under the name of _Académie Royale de Musique_, was situated on the Boulevard, near the _Porte St. Martin_. Except the façade, which has been admired, there was nothing very remarkable in the construction of this theatre, but the dispatch with which it was executed.
