rocks, and then like a bubble that is blown and detaches itself

the moon floated off clear into the unfathomable dark sky....
And then Karenin stood up. He walked a few paces along the

terrace and remained for a time gazing up at that great silver
disc, that silveryshield that must needs be man's first conquest

in outer space....
Presently he turned about and stood with his hands folded behind

him, looking at the northward stars. . . .
At length he went to his own cell. He lay down there and slept

peacefully till the morning. And early in the morning they came
to him and the anaesthetic was given him and the operation

performed.
It was altogether successful, but Karenin was weak and he had to

lie very still; and about seven days later a blood clot detached
itself from the healing scar and travelled to his heart, and he

died in an instant in the night.
