"The telephones so constructed were placed in different rooms. […] Upon singing into the telephone, the tones of the voice were reproduced by the instrument in the distant room. When two persons sang simultaneously into the instrument, two notes were emitted simultaneously by the telephone in the other house. […] I placed the membrane of the telephone near my mouth, and uttered the sentence, "Do you understand what I say?" Presently an answer was returned through the instrument in my hand. Articular words proceeded from the clock-spring attached to the membrane, and I heard the sentence, "Yes; I understand you perfectly.""

"In the terminology associated with this phenomenon, Jach Pursel is known as a "channel"—a vehicle through which "entities" from other planes of existence choose to address human beings. In a more familiar metaphor, Jach is the telephone through which Lazaris places his long distance calls: very long distance calls."

"If a string of packthread be attached to the stem of a tuning fork, and the other end of the thread be wrapt round the little finger, and placed in the chamber of the ear, the sound of the fork, when made to vibrate, will be heard at the end of the thread, though two hundred yards distant, while it is altogether imperceptible to a bystander. It has been suggested, that telegraphs, or, more properly speaking, telephones, might be invented upon this principle. The author states that some such instruments have been already perfected, and are about to be exhibited, but we have as yet heard nothing of them."

"It is not easy to say from these passages (which are all we could find on the subject) what plan [Edward] Davy had in contemplation. In the first quotation he speaks of bells, for which we may read a powerful trumpet at one end, and a concave reflector to focus the sound at the other end; or some arrangement like the compressed-air telephone, proposed by Captain Taylor, R.N., in 1844; […]"
