it proved to be the student to whom Kennedy had telephoned at his own
laboratory. He was carrying a heavy suitcase and a small tank.

Kennedy opened the suitcase hastily and disclosed a little motor, some
long tubes of rubber fitting into a small rubber cap, forceps, and
other paraphernalia. The student quickly attached one tube to the
little tank, while Kennedy grasped the tongue of the dead man with the
forceps, pulled it up off the soft palate, and fitted the rubber cap
snugly over his mouth and nose.

"This is the Draeger pulmotor," he explained as he worked, "devised
to resuscitate persons who have died of electric shock, but actually
found to be of more value in cases of asphyxiation. Start the motor."

The pulmotor began to pump. One could see the dead man's chest rise as
it was inflated with oxygen forced by the accordion bellows from the
tank through one of the tubes into the lungs. Then it fell as the
oxygen and the poisonous gas were slowly sucked out through the other
tube. Again and again the process was repeated, about ten times a
minute.

Dr. Burnham looked on in undisguised amazement. He had long since
given up all hope. The man was dead, Medically dead, as dead as ever
was any gas victim at this stage on whom all the usual methods of
resuscitation had been tried and had failed.

Still, minute after minute, Kennedy worked faithfully on, trying to
discover some spark of life and to fan it into flame. At last, after
what seemed to be a half-hour of unremitting effort, when the oxygen
had long since been exhausted and only fresh air was being pumped into
