A Remarkable Discovery.
■ ■ + ■Recently in America, Mr G. L. Roberta, an electrician, made by haphazard, what, if all acflolints are true, is correctly described as a very remarkable discovery. He was exiti his' laboratory and on the table was soitie satid* over which two wires had fallen across one another. By an accident a bottle a certain acid was overturned, and some of the acid ran into the sand at the point where the wires crossed. The immediate result was a series of electric sparks. Mr Roberts has now invented a lamp which is charged with sand, into which two wires are run, which connect,with an ordinary electric bulb, a current is established, which displays the well-known brilliant light of an electric lamp. The lamp will burn for 600 hours, when the sand can be renewed at a cost of B£d.
