Samuel Heinicke first began his work in 1754 at Dresden, but in 1778 he removed to Leipzig and started on the instruction of nine pupils. His methods he kept secret; but we know that he taught orally, using signs only when he considered them helpful, and spelling only to combine ideas. He wrote two books and several articles on the subject of educating the deaf, but it is from Walther and Fornari that we learn most about his system. At first Heinicke laid stress on written language, starting with the concrete and going on to the abstract; and he only passed to oral instruction when the pupils could express themselves in fairly correct language. Subsequently, however, he expressed the opinion that speech should be the sole method of instruction, and, strange to say, that by speech alone could thoughts be fully expressed.

Henry Baker became tutor to a deaf girl in 1720, and his success led to the establishment of a private school in London. He also kept his system a secret, but recently his work on lessons for the deaf was discovered, from which we gather that he adopted writing, drawing, speech and lip-reading as his course of instruction. The point to notice is that after the primary stages Baker turned events of every-day life to use in his teaching. His pupils went about with him, and he taught by conversation upon what they saw in the streets,--an excellent method; but it is a pity that such a good teacher had not the philanthropy to make his methods known and to give the poorer deaf the benefit of them, as de l'Epée did.

A school was established in Edinburgh in 1760 by Thomas Braidwood, who taught by the oral method. He taught the sounds first, then syllables, and finally words, teaching their meaning. In 1783 Braidwood came to Hackney, whence he moved to Old Kent Road, and in 1809 there were seventy pupils in what was lately the Old Kent Road Institution. Braidwood's method was practically a development of Wallis's. We must regard him as the founder of the first public school for the deaf in England.

It was only at the beginning of the 19th century that a brighter day dawned on the deaf as a class. With the sole exception of de l'Epée no teacher had yet undertaken the instruction of a deaf child who could not pay for it. Now things began to be different. Institutions were founded, and their doors were opened to nearly all.
