Special General Meeting, held at 25, Great George Street, Westminster, on Wednesday, the 31st October, 1877. PROFESSOR ABEL, C.B., F.R.S., President, in the Chair. The PRESIDENT: Gentlemen, the Council of the Society of Telegraph Engineers felt that they were sure of doing what the members would consider right in summoning a special meeting for the two-fold purpose of giving a welcome to Professor Bell to this country and affording the Members an opportunity of hearing from him an account, which he has been so good as to promise to give us, of the nature, history, and development of, what may well be called, one of the most interesting discoveries of our age. Our time is very precious this evening. We all desire to hear everything Professor Bell can tell us on this subject, and many gentlemen will probably desire afterwards to ask questions or discuss the subject, for I see present a great number of eminent scientific men. I will not waste another moment, but at once call upon Professor Bell to commence his discourse on the Electric Telephone. RESEARCHES IN ELECTRIC TELEPHONY. By PROFESSOR ALEXANDER GRAHAM BELL.
