  • the original and final object of all telegraphing is the communication of intelligence ata distance by signs or signals.
  • the electric telegraph is a more vrecent lkind of telegraph proposed within the last century; but no practical plan was devised until about sixteen4 years ago. Its distinguishing feature is the employment of electricity to et'- feetv the same general result of communicating intelligence at a distance by signs or signals.
  • I do not therefore claim to have first/applied electricity to telegraphing for the purpose of showin gevanescent signs
  • the original and final object of my telegraph isto imprint characters'at any distance as siguals for intelligence. Its object is tomark or impress them .in a permanent manner.
  • I have applied electricity in l novel process the motive power of electro-magnetism,or magnetism produced by electricity, ⁇ to operate machinery for printing signals at any distance; second, I have applied the chemical eliects of Aelectricity to print signals at any distance.
  • H H are the coils or helices ofthe magnet, being part of the main'circuit magnet in a form to enable me to enlarge the coilsor, ⁇ v helices without separating to an inother.
