to fulfill his promise, and asking her what message he should send. To this he received the following reply: WHAT HATH GOD WROUGHT! Words that ought to be written in characters of living light. The message was twice repeated, and each time with the greatest success. As soon as the result of the experiment was made known, Governor Seymour, of Connecticut, afterwards United States minister at St. Petersburg, called upon Professor Morse and claimed the first message for his State, on the ground that Miss Ellsworth was a native of Hartford. We need scarcely add that his claim was admitted; and now, engraved in letters of gold, it is displayed conspicuously in the archives of the Historical Society of Connecticut. Nothing New Under the Sun. FORESHADOWINGS OF THE MAGNETIC TELEGRAPH. THE Prolusiones Academicæ of Famianus Strada, first printed in 1617, consist of a series of essays upon Oratory, Philosophy, and Poetry, with some admirable imitations of sundry Roman authors, in the style of Father Prout's Reliques. In the imitation of Lucretius, ii. 6, is a description of the loadstone and its power of communicating intelligence, remarkable as foreshadowing the modern method of telegraphic communication. The following is a literal transla tion of the curious passage: The Loadstone is a wonderful sort of mineral. Any articles made of iron, like needles, if touched by it, derive by contact not only peculiar power, but a certain property of motion by which they turn ever towards the Constellation of the Bear, near the North Pole. By some peculiar correspondency of impulse, any number of needles, which may have touched the loadstone, preserve at all times a precisely corresponding position and motion. Thus it happens that if one needle be moved at Rome, any other, however far apart, is bound by some secret natural condition to follow the same motion. If you desire, therefore, to communicate intelligence to a distant friend, who cannot be reached by letter, take a plain, round, flat disc, and upon its outer rim mark down the letters of the alphabet, A, B, C, &c., and, traversing upon the middle of your disc, have a needle (which has touched loadstone) so arranged that it may be made to touch upon any particular letter ad libitum. Make a similar disc, the exact duplicate of this first one, with corresponding letters on its margin, and with a revolving magnetized needle. Let the friend you propose corresponding with take, at his departure, one disc along with him, and let him agree with you beforehand on what particular days and at what particular hours he will take observation of the needle, to see if it be vibrating and to learn what it marks on the index. With this arrangement understood between you both, if you wish to hold a private conversation with this friend, whom the shores of some distant land have separated from you, turn your finger to the disc and touch the easy-moving needle. Before you lie, marked upon the outer edge, all the various letters: direct the needle to such letters as are necessary to form the words you want, touching a little letter here and there with the needle's point, as it goes traversing round and round the board, until you throw together, one by one, your various ideas. Lo! the wonderful fidelity of correspondence! Your distant friend notes the revolving needle vibrate without apparent impulse and fly hither and thither round the rim. He notes its movements, and reading, as he follows its motion, the various letters which make up the words, he perceives all that is necessary, and learns your meaning from the interpreting needle. When he sees the needle pause, he, in turn, in like manner touches the various letters, and sends back his answer to his friend. Oh that this style of writing were brought into use, that a friendly message might travel quicker and safer, defying snares of robbers or delaying rivers! Would that the prince himself would finish the great work with his own hands! Then we race of scribblers, emerging from our sea of ink, would lay the quill an offering on the altars of the loadstone. This idea of Strada is based upon the erroneous impression entertained generally at the time when he wrote, that magnetic power, when imparted by the loadstone to metallic articles like needles, communicated to them a kind of homogeneous impulse, which of necessity caused between them a sympathetic correspondence of motion. The curious reader will be further interested to learn from the following passage, extracted from the "Tour" of ARTHUR YOUNG, the distinguished agriculturist, who travelled through Ireland in 1775-78, that the theory of electrical correspondence by means of a wire was practically illustrated before Mr. Morse was born: In electricity, Mons. Losmond has made a remarkable discovery. You write two or three words on a paper; he takes it with him into a room, and turns a machine enclosed in a cylindrical case, at the top of which is an electrometer, in the shape of a small fine pith ball. A wire connects with a similar cylinder and electrometer in a distant apartment, and his wife, by remarking the corresponding motions of the ball, writes down the words. they indicate, from which it appears that he has formed an alphabet of motions. As the length of wire makes no difference in the effect, a correspondence might be carried on at any distance, within and without a besieged town, for instance, or for a purpose much more worthy and a thousand times more harmless, between two lovers, prohibited or prevented from any better epistolary intercourse. A second edition of Mr. Young's Tour was published in quarto in 1794, and the above extract may be found on page 79, volume i. THE FIRST DISCOVERIES OF STEAM-POWER. The following extracts from an address by Edward Everett, at an agricultural fair, embody facts the more interesting from their limited notoriety : I never contemplate the history of navigation of the ocean by steam, but it seems to illustrate to me in the most striking manner the slow steps by which a great movement advances for generations, for ages, from the first germ, then, when the hour is come, the rapidity with which it rushes to a final consummation. Providence offered this great problem of navigating the ocean by steam to every civilized nation almost on the globe. As long ago as the year 1543, there was a captain in Spain, who constructed a vessel of two hundred tons, and propelled it, at Barcelona, in the presence of the Emperor Charles V. and his court, by an engine, the construction of which he kept a secret. But old documents tell us it was a monster caldron boiler of water, and that there were two movable wheels on the outside of the vessel. The Emperor was satisfied with its operation, but the treasurer of the kingdom interposed objections to its introduction. The engine itself seems to have sprung to a point of perfection hardly surpassed at the present day, but no encouragement was given to the enterprise. Spain was not ripe for it; the age was not ripe for it; and the poor inventor, whose name was Blasco de Guerere, wearied and disgusted at the want of patronage, took the engine out of the vessel and allowed the ship to rot in the arsenal, and the secret of his machine was buried in his grave. This was in 1543. A century passed away, and Providence offered the same problem to be solved by France. In reference to this, we have an extraordinary account, and from a source equally extraordinary,-from the writings of a celebrated female, in the middle of that century, equally renowned for her beauty, for her immoralities, and for her longevity, for she lived to be one hundred and thirty-four years of age,—the famous Marian de l'Orme. There is a letter from this lady, written to one of her admirers in 1641, containing an account of a visit she made to a mad-house in Paris in company with the Marquis of Worcester. She goes on to relate, that in company with the marquis, while crossing the courtyard of that dismal establishment, almost petrified with terror, and clinging to her companion, she saw a frightful face through the bars of the building, and heard this voice:-"I am not mad-I am not mad: I have made a discovery which will enrich the kingdom that shall adopt it." She asked the guide what it meant: he shrugged his shoulders and said, laughingly, "Not much; something about the powers of steam." Upon this, the lady laughed also, to think that a man should go mad on such a frivolous subject. The guide went on to say that the man's name was Solomon de Coste; that he came from Normandy four years before, and exhibited to the king an invention by which, by the power of steam, you could move a carriage, navigate the ocean: "in short, if you believed him," said the guide, "there was nothing you could not do by the power of steam." Cardinal Richelieu, who at that time was France itself, and who wielded the whole power of government, and, in truth, an enlightened man, as worldly wisdom goes,-was appealed to by Solomon de Coste. De Coste was a persevering man, and he followed Cardinal Richelieu from place to place, exhibiting his invention, until the cardinal, getting tired of his importunities, sent him to the mad-house. The guide stated further that he had written a book entitled Motive Power, and handed the visitors a copy of it. The Marquis of Worcester, who was an inventor, was much interested in the book, and incorporated a considerable portion of it in his well-known work called The Century of Invention. It will be seen from this anecdote how France proved in 1641, as Spain had proved in 1543, that she was unable to take |
