I do not mean to mention the instruction of the deaf as new. Having been first practised upon the son of a constable of Spain, it was afterwards cultivated with much emulation in England, by Wallis and Holder, and was lately professed by Mr. Baker, who once flattered me with hopes of seeing his method published. How far any former teachers have succeeded, it is not easy to know; the improvement of Mr. Braidwood's pupils is wonderful. They not only speak, write, and understand what is written, but if he that speaks looks towards them, and modifies his organs by distinct and full utterance, they know so well what is spoken, that it is an expression scarcely figurative to say, they hear with the eye. That any have attained to the power mentioned by Burnet, of feeling sounds, by laying a hand on the speaker's mouth, I know not; but I have seen so much, that I can believe more; a single word, or a short sentence, I think, may possibly be so distinguished.
