He tells us that the two friends, being each of them possessed of one of those needles, made a kind of dial-plate, inscribing it with four-and-twenty letters, in the same manner as the hours of the day are marked upon the ordinary dial-plate.

They then fixed one of the needles on each of these plates in such a manner that it could move round without impediment, so as to touch any of the four-and-twenty letters.
"Upon their separating from one another into distant countries, they agreed to withdraw themselves punctually into their closets at a certain hour of the day, and to converse with one another by means of this their invention.
"Accordingly, when they were some hundred miles asunder, each of them shut himself up in his closet at the time appointed, and immediately cast his eye upon his dial-plate.

If he had a mind to write anything to his friend, he directed his needle to every letter that formed the words which he had occasion for, making a little pause at the end of every word or sentence, to avoid confusion.
"The friend in the meanwhile saw his own sympathetic needle moving of itself to every letter which that of his correspondent pointed at.

By this means they talked together across a whole continent, and conveyed their thoughts to one another in an instant over cities or mountains, seas or deserts.
"If Monsieur Scudery, or any other writer of romance, had introduced a necromancer, who is generally in the train of a knight-errant, making a present to two lovers of a couple of these above-mentioned needles, the reader would not have been a little pleased to have seen them corresponding with one another when they were guarded by spies and watchers, or separated by castles and adventures.
"In the meanwhile, if ever this invention should be revived or put in practice, I would propose that upon the lover's dial-plate there should be written not only the four-and-twenty letters, but several entire words which have always a place in passionate epistles, as flames, darts, die, language, absence, Cupid, heart, eyes, hang, drown, and the like.

This would very much abridge the lover's pains in this way of writing a letter, as it would enable him to express the most useful and significant words with a single touch of the needle .-- C." Thus far Addison, a hundred and seventy years ago, and Strada (whoever he may be, for ordinary biographical dictionaries ignore him), perhaps fifty before him, and the two unknown experimentalists, perhaps twenty beyond that, making in all two hundred and forty or fifty years ago as the date of electrical invention: whereof we see no further mention in the _Spectator_.
