"Scientific American Supplement, No. 458, October 11, 1884"

A newly
invented instrument has been described to me, which, if it does what has
been affirmed, is one of the greatest and most wonderful discoveries of
modern science. A very thin platinum wire loop, brought to incandescence
by the current from a battery--which, though of great power, is so small
that it hangs from the lapel of the operator's coat--is used instead of a
knife for excisions and certain amputations. It sears as it cuts, prevents
the loss of blood, and is absolutely painless, which is the most
astonishing thing about it.
"Our greatest consumers of platinum are the electricians, particularly the
incandescent light companies. I supply the platinum wire for both the
Edison and the Maxim companies, and the quantity they require so
constantly increases that the demand threatens to exceed the supply of the
metal. Sheets of platinum are bought by chemists, who have them converted
into crucibles and other forms."
The reporter's curiosity was awakened by Mr. Baker's mention of the old
lady who made those very fine draw plates, and on his return to the city
he hunted her up. Mrs. Francis A. Jeannot, the lady in question, was found
in neat apartments in a handsome flat in West Fifty-first street.
