Edison and phonograph

AT the opening of the Electrical Show in New York City in October, 1908, to celebrate the jubilee of the Atlantic Cable and the first quarter century of lighting with the Edison service on Manhattan Island, the exercises were all conducted by means of the Edison phonograph. This included the dedicatory speech of Governor Hughes, of New York; the modest remarks of Mr. Edison, as president; the congratulations of the presidents of several national electric bodies, and a number of vocal and instrumental selections of operatic nature. 
All this was heard clearly by a very large audience, and was repeated on other evenings. The same speeches were used again phonographically at the Electrical Show in Chicago in 1909—and now the records are preserved for reproduction a hundred or a thousand years hence. This tour de force, never attempted before, was merely an exemplification of the value of the phonograph not only in establishing at first hand the facts of history, but in preserving the human voice. What would we not give to listen to the very accents and tones of the Sermon on the Mount, the orations of Demosthenes, the first Pitt's appeal for American liberty, the Farewell of Washington, or the Address at Gettysburg? Until Edison made his wonderful invention in 1877, the human race was entirely without means for preserving or passing on to posterity its own linguistic utterances or any other vocal sound. We have some idea how the ancients looked and felt and wrote; the abundant evidence takes us back to the cave-dwellers. But all the old languages are dead, and the literary form is their embalmment. We do not even know definitely how Shakespeare's and Goldsmith's plays were pronounced on the stage in the theatres of the time; while it is only a guess that perhaps Chaucer would sound much more modern than he scans. 
The analysis of sound, which owes so much to Helmholtz, was one step toward recording; and the various means of illustrating the phenomena of sound to the eye and ear, prior to the phonograph, were all ingenious. One can watch the dancing little flames of Koenig, and see a voice expressed in tongues of fire; but the record can only be photographic. In like manner, the simple phonautograph of Leon Scott, invented about 1858, records on a revolving cylinder of blackened paper the sound vibrations transmitted through a membrane to which a tiny stylus is attached; so that a human mouth uses a pen and inscribes its sign vocal. Yet after all we are just as far away as ever from enabling the young actors at Harvard to give Aristophanes with all the true, subtle intonation and inflection of the Athens of 400 B.C. The instrument is dumb. Ingenuity has been shown also in the invention of "talking-machines," like Faber's, based on the reed organ pipe. These automata can be made by dexterous manipulation to jabber a little, like a doll with its monotonous "ma-ma," or a cuckoo clock; but they lack even the sterile utility of the imitative art of ventriloquism. The real great invention lies in creating devices that shall be able to evoke from tinfoil, wax, or composition at any time to-day or in the future the sound that once was as evanescent as the vibrations it made on the air. 

Murder of Caesar

Upon his return from Spain, Caesar granted pardon to all who had fought against him, the most prominent of whom were GAIUS CASSIUS, MARCUS BRUTUS, and CICERO. He increased the number of the Senate to nine hundred. He cut off the corn grants, which nursed the city mob in idleness.
He sent out impoverished men to colonize old cities. He rebuilt Corinth, and settled eighty thousand Italians on the site of Carthage. As a censor of morals he was very rigid. His own habits were marked by frugality. The rich young patricians were forbidden to be carried about in litters, as had been the custom. Libraries were formed. Eminent physicians and scientists were encouraged to settle in Rome. The harbor of Ostia was improved, and a road constructed from the Adriatic to the Tyrrhenian Sea, over the Apennines. A temple to Mars was built, and an immense amphitheatre was erected at the foot of the Tarpeian Rock.In the midst of this useful activity he was basely murdered.CASSIUS LONGINUS and MARCUS JUNIUS BRUTUS were the leaders in the conspiracy to effect Caesar's death, Cassius, a former lieutenant of Crassus, had shown great bravery in the war with the Parthians.
At Pharsalia he fought on the side of Pompey, but was afterwards pardoned by Caesar. He was married to a sister of Brutus. The latter, a nephew and son-in-law of Cato, had also fought at Pharsalia against Caesar, and also been pardoned by him. Cassius, it was said, hated the tyrant, and Brutus tyranny.These conspirators were soon joined by persons of all parties; and men who had fought against each other in the civil war now joined hands. Cicero was not taken into the plot. He was of advanced years, and all who knew him must have felt that he would never consent to the taking the life of one who had been so lenient towards his conquered enemies.On the morning of the IDES (15th) OF MARCH, 44, as Caesar entered the Senate and took his seat, he was approached by the conspirators, headed by Tullius Cimber, who prayed for the pardon of his exiled brother; and while the rest joined him in the request, he, grasping Caesar's hand, kissed his head and breast. As Caesar attempted to rise, Cimber dragged his cloak from his shoulders, and Casca, who was standing behind his chair, stabbed him in the neck.
The first blow was struck, and the whole pack fell upon their noble victim. Cassius stabbed him in the face, and Marcus Brutus in the groin. He made no further resistance; but, wrapping his gown over his head and the lower part of his body, he fell at the base of POMPEY'S STATUE, which was drenched with the martyr's blood.Great tumult and commotion followed; and, in their alarm, most of the Senators fled. It was two days before the Senate met, the conspirators meanwhile having taken refuge in the Capitol. Public sentiment was against them. Many of Caesar's old soldiers were in the city, and many more were flocking there from all directions. The funeral oration of Mark Antony over the remains produced a deep impression upon the crowd. They became so excited when the speaker removed the dead man's toga, and disclosed his wounds, that, instead of allowing the body to be carried to the Campus Martius for burial, they raised a funeral pile in the Forum, and there burned it. The crowd then dispersed in troops, broke into and destroyed the houses of the conspirators. Brutus and Cassius fled from the city for their lives, followed by the
other murderers.
As a general Caesar was probably superior to all others, excepting possibly Hannibal. He was especially remarkable for the fertility of his resources. It has been said that Napoleon taught his enemies how to conquer him; but Caesar's enemies never learned how to conquer him, because he had not a mere system of tactics, but a new stratagem for every emergency. He was, however, not only a great general, but a pre- eminent statesman, and second only to Cicero in eloquence. As a historian, he wrote in a style that was clear, vigorous, and also simple. Most of his writings are lost; but of those that remain Cicero said that fools might try to improve on them, but no wise man would attempt it.

Giant Jupiter

And now let us bow respectfully before Jupiter, the giant of the worlds. This glorious planet is indeed King of the Solar System.

While Mercury measures only 4,750 kilometers (2,946 miles) in diameter, and Mars 6,728 kilometers (4,172), Jupiter is no less than 140,920 kilometers (87,400 miles) in breadth; that is to say, eleven times larger than the Earth. He is 442,500 kilometers (274,357 miles) in circumference.

In volume he is equivalent to 1,279 terrestrial globes; hence he is only a million times smaller than the Sun. The previously described planets of our system, Mercury, Venus, the Earth, and Mars combined, would form only an insignificant mass in comparison with this colossus. A hundred and twenty-six Earths joined into one group would present a surface whose extent would still not be quite as vast as the superficies of this titanic world. This immense globe weighs 310 times more than that which we inhabit. Its density is only the quarter of our own; but weight is twice and a half times as great there as here. The constituents of things and beings are thus composed of materials lighter than those upon the Earth; but, as the planet exerts a force of attraction twice and a half times as powerful, they are in reality heavier and weigh more. A graceful maiden weighing fifty kilograms would if transported to Jupiter immediately be included in the imposing society of the "Hundred Kilos."

Jupiter rotates upon himself with prodigious rapidity. He accomplishes his diurnal revolution in less than ten hours! There the day lasts half as long as here, and while we reckoned fifteen days upon our calendar, the Jovian would count thirty-six. As Jupiter's year equals nearly twelve of ours, the almanac of that planet would contain 10,455 days! Obviously, our pretty little pocket calendars would never serve to enumerate all the dates in this vast world.

THE MYSTERY OF THE PYRAMIDS

Few subjects of inquiry have proved more perplexing than the question of the purpose for which the pyramids of Egypt were built. Even in the remotest ages of which we have historical record, nothing seems to have been known certainly on this point. For some reason or other, the builders of the pyramids concealed the object of these structures, and this so successfully that not even a tradition has reached us which purports to have been handed down from the epoch of the pyramids' construction.
We find, indeed, some explanations given by the earliest historians; but they were professedly only hypothetical, like those advanced in more recent times. Including ancient and modern theories, we find a wide range of choice. Some have thought that these buildings were associated with the religion of the early Egyptians; others have suggested that they were tombs; others, that they combined the purposes of tombs and temples, that they were astronomical observatories, defences against the sands of the Great Desert, granaries like those made under Joseph's direction, places of resort during excessive overflows of the Nile; and many other uses have been suggested for them. But none of these ideas are found on close examination to be tenable as representing the sole purpose of the pyramids, and few of them have strong claims to be regarded as presenting even a chief object of these remarkable structures. The significant and perplexing history of the three oldest pyramids—the Great Pyramid of Cheops, Shofo, or Suphis, the pyramid of Chephren, and the pyramid of Mycerinus; and the most remarkable of all the facts known respecting the pyramids generally, viz., the circumstance that one pyramid after another was built as though each had become useless soon after it was finished, are left entirely unexplained by all the theories above mentioned, save one only, the tomb theory, and that does not afford by any means a satisfactory explanation of the circumstances.
