And of late, during the long and still watches of the night, while he stared at the ceiling, or counted the hours that must pass before his next dose of bromide of potassium, a new turn had been given to the screw.

This was a sensation, the like of which he found it difficult to describe. But it seemed to be a slow, tense crisping of every tiniest nerve in his body. It would begin as he lay in bed⁠—counting interminably to get himself to sleep⁠—between his knees and ankles, and thence slowly spread to every part of him, creeping upward, from loin to shoulder, in a gradual wave of torture that was not pain, yet infinitely worse. A dry, pringling aura as of billions of minute electric shocks crept upward over his flesh, till it reached his head, where it seemed to culminate in a white flash, which he felt rather than saw.

His body felt strange and unfamiliar to him. It seemed to have no weight, and at times his hands would appear to swell swiftly to the size of mammoth boxing-gloves, so that he must rub them together to feel that they were his own.
