• The other side of the local circuit was permanently connected to an insulated block on the vibrator. Frank Lewis Dyer. Edison, His Life and Inventions.
• The coil and disks are supported by the strong and well-insulated rod _R_, which rests upon braces, but which nevertheless rotates freely with disks and coil. Bertha M. Clark. General Science.
• When the work of actually making communication by insulated wires between places far apart came to be done, much difficulty arose as to the best and cheapest mode of doing it. Frederick C. Bakewell. Great Facts.
• Mr. Ronalds so far perfected his invention, that it worked accurately, though slowly, through eight miles of wire insulated in glass tubes. Frederick C. Bakewell. Great Facts.
