MARCONI'S LATEST.

SIGNALLING THIRTY MILES FROM

A MOTORCAR

Mil. Marconi delivered a most interesting lecture on his syntonic system of wireless telegraphy tore the (Society of Arts on May 15.

A great advance has been made in the new science, one gathered, by using receivers and transmitting which are "in tune," With each oilier. Tins has vastly lessened the height uf the transmitter, hitherto the chief obstacle to extending the distances signalled over. Syntonic signalling has been carried out, said Mr. Marconi, over thirty kilometres with ,i cylinder only -lit high and 4(J:u in diameter." "it is now possible," he said, "to construct a portable apparatus for army purposes. 1 have made a complete installation on a steam motor ear, with which I have easily-communicated over thirty miles.

" Such an appliance would have been of use tjo the besieged garrisons in South Africa and China. 1 trust to have the opportunity of showing it to the War Office in a few davs."

Lately, add tin lecturer, he had communicated between the Lizard and St. Catherine's Point, Isle of White, about 190 miles, which was a record distance.

"In March, 1900, resumed Mr. Marconi, "there were in use in the .Royal navy in South African waters live installations of my system. hi the following May the Admiralty decided to extend it to thirty-two more ships and land stations."

Humanity would ere long, predicted the inventor, recognise wireless telegraphy as the most potent safeguard yet devised to reduce the perils of the world's sea-going population..
