We are not to suppose that the Chappe method of telegraphing became extinct after its first successful work. Other references to what we _suppose_ to be the same instrument are found in the literature of the age. The wonder is that more was not written and more accomplished by the agency of Chappe's invention. In the fall of the year 1800, General Bonaparte, who had been in Egypt and the East, returned to Europe and landed at Frejus on his way to Paris, with the dream of universal dominion in his head. In the first volume of the _Memoirs of Napoleon Bonaparte_, his secretary M. de Bourrienne, writing of the return to France says:
"We arrived in Paris on the 24th Vendemiaire (the sixteenth of October). As yet he (Napoleon) knew nothing of what was going on; for he had seen neither his wife nor his brothers, who were looking for him on the Burgundy Road. The news of our landing at Frejus had reached Paris _by a_ _telegraphic despatch_. Madame Bonaparte, who was dining with M. Gohier when that despatch was communicated to him, as President of the Directory, immediately set off to meet her husband," etc. We should be glad to know in what particular form that "telegraphic despatch" was delivered! But such are Bourrienne's words!
To the American reader the name of Karl Friedrich Gauss may have an unfamiliar sound. Gauss was already a youth of fourteen when Morse was born, though the latter outlived the German mathematician by seventeen years. Gauss was a professor of Mathematics at Göttingen, where he passed nearly the whole of his life. In the early part of the century he distinguished himself in astronomy and in other branches of physical science. He then became interested in magnetic and electrical phenomena, and in 1833, with the assistance of Wilhelm Eduard Weber, one of his fellow-professors, who died in 1891, he erected at Göttingen a magnetic observatory. There he began to experiment with the subtle agent which was soon to be placed at the service of mankind.
The observatory was constructed without the use of iron, in order that the magnetic phenomena might be studied under favorable conditions. Humboldt and Arago had previously constructed laboratories without using iron--for iron is the great disturber--and from them Gauss obtained his hint. Weber was also expert in the management of magneto-electrical currents. Gauss, with the aid of his co-worker, constructed a line of telegraph, and sent signals by the agency of the magnetic current to a neighboring town. This was nearly ten years before Morse had fully succeeded in like experimentation.
