the following year, in repeating Franklin's experiment, was killed by a stroke of lightning. Charles Marshall, in 1753, proposed insulated wires, suspended by poles, as electrical conductors for transmitting messages. Lesarge, in 1774, used twenty-four electrized wires and a pith-ball electrometer as a mode of signaling. Lomond, in 1787, used one wire and a pith-ball. Reizen, in 1794, had twenty-six line wires and letters in tin-foil which were rendered visible by electricity. Cavallo, in 1795, had one wire, and talked by sparks. He had an explosion of gas for an alarm. 2. (Surgical.) A grooved staff for directing a penetrating instrument in surgical operations; such as the forceps in extracting balls; lithontriptic instruments, etc. Conduit. (Hydraulic Engineering.) A pipe or passage, usually covered, for conducting water. Conduit of the Pont du Gard. Cone. The ventplug which is screwed into the barrel of a fire-arm (A, Fig. 1424). The outer end
f each wire having a pith-ball electroscope attached. Lamond, in 1787, employed a single wire, employing an electrical machine and electroscope in each of two rooms, and thus talking with Madame Lamond by the peculiar movements of the pith-balls according to an agreed code; and Reusser, in 1794, proposed the employment of letters formed by spaces cut out of parallel strips of tin-foil pasted on sheets of glass, which would appear luminous on the passage of the electric spark. In 1795, Cavallo proposed to transmit letters and numbers by a combination of sparks and pauses. Don Silva, in Spain, appears to have previously suggested a similar process. See electrical apparatus. In 1816, Mr. Ronalds experimented with a frictional electricity telegraph at Hammersmith. The current had to pass through eight miles of wire, and the signals were made by means of light pith-balls. The reading was effected by dials at each station having a synchronous movement derived from clockwork.
ion that contains no nitrate of silver being as transparent as if the dark places were solid wires or metallic plates placed in the focus of the eye-glass. See Pearson's Practical astronomy, Vol. II.: Brewster's Philosophical instruments. Cavallo's micrometer is a small, semi-transparent scale of mother-of-pearl, about 1/20 of an inch broad and divided by finely ruled lines.
