There is no difficulty about that; the difficulty is to set up
a rapid enough vibration to whirl the current through!" He said that in
meditative fashion: he was clearly at the moment repeating the working
out of the problem.
"I see," said the young man, looking thoughtful.
"Now, you are a musician, are you not?"
"I play a little," said the young man, with a bewildered look.
"You play the violin?"
"Yes."
"And, of course, you have it in your rooms. Would you be so good as
to bring me the bow of your violin, and borrow for me anywhere a
tuning-fork of as high a note as possible?"
The young man looked at Dr Lefevre in puzzled inquiry; but the doctor
was considering the electrical apparatus before him, and the young man
set off on his errands. When he returned with the fiddle-bow and the
tuning-fork, he saw Lefevre had placed the machine ready, with fresh
chemicals in the vessels.
"Do you perceive my purpose?" asked Lefevre. He placed one handle of the
apparatus in the unconscious patient's right hand, while he himself took
hold of her left arm with his right hand, so that the inner side of his
wrist was in contact with the inner side of hers; and then, to complete
the circle of connection, he took in his left hand the other handle of
the apparatus.
