This experiment was made by Joseph Franz, of Vienna, in 1746, 
and Dr. Watson, of London, in 1747; while Franklin ignited spirits by a 
spark which had been sent across the Schuylkill river by the same 
means. But none of these men seem to have grasped the idea of 
employing the fleet fire as a telegraph. 
The first suggestion of an electric telegraph on record is that published 
by one 'C. M.' in the Scots Magazine for February 17, 1753. The device 
consisted in running a number of insulated wires between two places, 
one for each letter of the alphabet. The wires were to be charged with 
electricity from a machine one at a time, according to the letter it 
represented. At its far end the charged wire was to attract a disc of 
paper marked with the corresponding letter, and so the message would 
be spelt. 'C. M.' also suggested the first acoustic telegraph, for he 
proposed to have a set of bells instead of the letters, each of a different 
tone, and to be struck by the spark from its charged wire. 
The identity of 'C. M.,' who dated his letter from Renfrew, has not been 
established beyond a doubt. There is a tradition of a clever man living 
in Renfrew at that time, and afterwards in Paisley, who could 'licht a 
room wi' coal reek (smoke), and mak' lichtnin' speak and write upon the 
wa'.' By some he was thought to be a certain Charles Marshall, from 
Aberdeen; but it seems likelier that he was a Charles Morrison, of 
Greenock, who was trained as a surgeon, and became connected with 
the tobacco trade of Glasgow. In Renfrew he was regarded as a kind of 
wizard, and he is said to have emigrated to Virginia, where he died.
In the latter half of the eighteenth century, many other suggestions of 
telegraphs based on the known properties of the electric fire were 
published; for example, by Joseph Bozolus, a Jesuit lecturer of Rome, 
in 1767; by Odier, a Geneva physicist, in 1773, who states in a letter to 
a lady, that he conceived the idea on hearing a casual remark, while 
dining at Sir John Pringle's, with Franklin, Priestley, and other great 
geniuses. 'I shall amuse you, perhaps, in telling you,' he says,'that I 
have in my head certain experiments by which to enter into 
conversation with the Emperor of Mogol or of China, the English, the 
French, or any other people of Europe ... You may intercommunicate 
all that you wish at a distance of four or five thousands leagues in less 
than half an hour. Will that suffice you for glory?' 
George Louis Lesage, in 1782, proposed a plan similar to 'C. M.'s,' 
using underground wires. An anonymous correspondent of the 
JOURNAL DE PARIS for May 30, 1782, suggested an alarm bell to 
call attention to the message. Lomond, of Paris, devised a telegraph 
with only one wire; the signals to be read by the peculiar movements of 
an attracted pith-ball, and Arthur Young witnessed his plan in action, as 
recorded in his diary. M. Chappe, the inventor of the semaphore, tried 
about the year 1790 to introduce a synchronous electric telegraph, and 
failed. 
Don Francisco Salva y Campillo, of Barcelona, in 1795, proposed to 
make a telegraph between Barcelona and Mataro, either overhead or 
underground, and he remarks of the wires, 'at the bottom of the sea 
their bed would be ready made, and it would be an extraordinary 
casualty that should disturb them.' In Salva's telegraph, the signals were 
to be made by illuminating letters of tinfoil with the spark. Volta's great 
invention of the pile in 1800 furnished a new source of electricity, 
better adapted for the telegraph, and Salva was apparently the first to 
recognise this, for, in the same year, he proposed to use it and interpret 
the signals by the twitching of a frog's limb, or the decomposition of 
water. 
In 1802, Jean Alexandre, a reputed natural son of Jean Jacques 
Rousseau, brought out a TELEGRAPHE INTIME, or secret telegraph, 
which appears to have been a step-by-step apparatus. The inventor 
concealed its mode of working, but it was believed to be electrical, and 
there was a needle which stopped at various points on a dial. Alexandre
stated that he had found out a strange matter or power which was, 
perhaps generally diffused, and formed in some sort the soul of the 
universe. He endeavoured to bring his invention under the eye of the 
First Consul, but Napoleon referred the matter to Delambre, and would 
not see it. Alexandre was born at Paris, and served as a carver and 
gilder at Poictiers; then sang in the churches till the Revolution 
suppressed this means of livelihood. He rose to influence as a 
Commissary-general, then retired
