Abstract

WE publish a remarkable paper this week, by Mr. J. Blyth, on a new form of the microphone, which needs neither battery nor telephone. The curious importance of Mr. Blyth's invention need not be insisted on. By backing-up the pictures in a drawing-room it might, as has been suggested by a learned professor, be converted into an Ear of Donysius, and Horace's words, “suppositos cineri doloso,” would come to have an awful meaning.
