After five minutes or so we returned and examined the thermometer.  It had risen to 98 degrees, the natural temperature of the human body.

“What do you make of that if the man is dead?” he whispered.

I shook my head, and as we had agreed, set to helping him to lift the body from the coffin.  It was a good weight, quite eleven stone I should say; moreover, it was not stiff, for the hip joints bent.  We got it out and laid it on a blanket we had spread on the floor of the sepulchre.  Whilst I was thus engaged I saw something that nearly caused me to loose my hold from astonishment.  Beneath the head, the centre of the back and the feet were crystal boxes about eight inches square, or rather crystal blocks, for in them I could see no opening, and these boxes emitted a faint phosphorescent light.  I touched one of them and found that it was quite warm.

“Great heavens!” I exclaimed, “here’s magic.”

“There’s no such thing,” answered Bickley in his usual formula.  Then an explanation seemed to strike him and he added, “Not magic but radium or something of the sort.  That’s how the temperature was kept up.  In sufficient quantity it is practically indestructible, you see.  My word! this old gentleman knew a thing or two.”

Again we waited a little while to see if the body begun to crumble on exposure to the air, I taking the opportunity to make a rough sketch of it in my pocket-book in anticipation of that event.  But it did not; it remained quite sound.

“Here goes,” said Bickley.  “If he should be alive, he will catch cold in his lungs after lying for ages in that baby incubator, as I suppose he has done.  So it is now or never.”

Then bidding me hold the man’s right arm, he took the sterilized syringe which he had prepared, and thrusting the needle into a vein he selected just above the wrist, injected the contents.

“It would have been better over the heart,” he whispered, “but I thought I would try the arm first.  I don’t like risking chills by uncovering him.”

I made no answer and again we waited and watched.

“Great heavens, he’s stirring!” I gasped presently.

Stirring he was, for his fingers began to move.

Bickley bent down and placed his ear to the heart—­I forgot to say that he had tested this before with a stethoscope, but had been unable to detect any movement.

“I believe it is beginning to beat,” he said in an awed voice.

Then he applied the stethoscope, and added, “It is, it is!”

Next he took a filament of cotton wool and laid it on the man’s lips.  Presently it moved; he was breathing, though very faintly.  Bickley took more cotton wool and having poured something from his medicine-chest on to it, placed it over the mouth beneath the man’s nostrils—­I believe it was sal volatile.
