Now there came another dart of light, thin and fleeting, and she knew that a knife was poised in mid-air. Involuntarily she closed her eyes tight; a shudder ran through her. Donald's voice spoke impersonally, and steadied her.

"I shall expose the third left frontal convolution of the brain through the fronto-parietal bone, and, in making the osteoplastic flap, I intend to leave a wide working margin above the size of the opening which may actually be necessary in order to reach the growth. It has got to be fully exposed at once. I can't afford to delay, under the circumstances."

The gleam of the scalpel held her unwilling gaze with the fascination of horror; she drew her breath with a sound between a shudder and a sigh as it descended....

"I must keep my eyes on the ether pad," came the command from her whirling brain.

Many nights thereafter, Rose was to start up from troubled sleep with strange sounds and stranger words echoing in her brain—words like "bevelled trephines," "Hudson forceps," "elevators," "Horsley's wax," "rongeurs," "clips" and "sponges,"—but during the actual operation she was scarcely conscious of them, and her principal feeling was one of dumb rebellion which grew until she found herself almost hating this Donald, who could speak with such unconcern and apparent callousness, at such a time. As well as she could, she willed her swimming gaze to remain fixed on the pad which she must keep moist. The difficulty of the task had suddenly become increased, for the pad seemed to become an animate thing. Now it appeared to retreat into the distance, and again it came floating back until it seemed about to smother her. There was a droning note in her ears; the words spoken by the other two sounded mixed and indistinct.

Of only one sentence, repeated monotonously in Miss Merriman's clear voice, was she really conscious. "Rose, a drop of ether ... a drop of ether ... a drop of ether."

She wanted to speak, to ask them if the room were not frightfully hot; but she could not.

Rose had never fainted in her life, but she had once seen a neighbor swoon, and she realized vaguely that, as the minutes passed, her consciousness was slowly slipping from her. The air was close and heavy with strange smells. She felt as though she were swaying like a pendulum. The old, familiar objects grew grotesquely large and hazy; the deep shadows in the corners multiplied, and began to dance a solemn minuet, advancing, retreating; advancing, retreating....

"Another drop of ether."

She took a fresh mental grasp on herself, and held Duty, like a visible thing, before her eyes.
