''Oh. l keep working away at it. :"
answered the inventor. ''OnlY an
hour ago Professor Barker. professor
of physics of the University of Pen.

several curious experiments with my
carbon telephone. He made colnec-

every word could be plainly heard.

Mr.. Edison has made several eX-
periments with this apparatus, and
has succeeded in measuring the fifty
thousandth part of Il degree Of heat.
Next month Professor Young and
Professor Bracket will 90 to Colorado
to observe the solar eclipse. and the
usefulness of this instrument for
measuring the heat of the heavenly
bodies will then be tested for the first
time.

An affirmative reply caused the in
ventor to bring out from corner two
large cone-shaped machines, each
about five feet in length. Their
object is to multiply sound, and
already marvellous results have been
achieved. Conversation has been car

erSOns in a farmhouse, over a mile
distant, and the professor standing
at the door of his laboratory. The
Professor expresses confidence that

inventions is the megaphOne. for
which he has but just filed his caveat.

''What is the history of this inven.
