"Will it hurt, doctor?" groaned Carroll, gazing upon the row of instruments with fascinated eyes.

"Before we are finished it is quite possible the patient may be conscious of nervous disturbance, accompanied by sensations more or less painful."

"Will it hurt, blank you!" replied Carroll, whose hoarse voice showed the intensity of his repressed emotion.

"As I was saying," said the doctor in his calm, even tone, and examining his instruments one by one with affectionate care, "there is every possibility that the nerve centres may be—"

"Oh," groaned Carroll, still fascinated by the instruments that the doctor was handling with such loving touches, "will someone shut up this blank, blatherin' fool? He'd drive a man crazy, so he wud!"

"Mr. Carroll, we must be calm. We must be entirely calm," observed the doctor. "Now," continuing his monologue, "we shall remove the hair from the field of operation. Cleanliness in an operation of this kind is of prime importance. Recent scientific investigations show that the chief danger in operations is from septic poisoning. Yes, every precaution must be taken. Then we shall bathe with this weak solution of carbolic—three percent will be quite sufficient, quite sufficient—the injured parts and the surrounding area, and then we shall examine the extent of the wound. If the dura mater be penetrated, and the arachnoid cavity be opened, then there will be in all probability a very considerable extravasation of blood, and by this time, doubtless, serious inflammation of all the surrounding tissues. The aperture being very small and the depression somewhat extensive, it will be necessary to remove—to saw out, in short—a portion of the skull," lifting up a fierce-looking instrument.

Carroll groaned.

"Let me out!" he whispered hoarsely, rising and feeling his way with outstretched hand to the door. "I can't stand this bloody divil!"

Ike opened the door, while Shock sprang to support the groping man.

"Lave me be!" he said fiercely, with a curse, and pushing Shock back he stumbled out.
