He felt as if he were under an intolerable physical strain, as if his body were likely at any moment to fly to pieces. Other strange physical symptoms came to trouble him. An unpleasant odour lingered in his nostrils, as if he could literally smell the sulphur of the pit; and he had from time to time the curious illusion that his flesh was turning black. He had to look continually at his hands to be sure that it was not so. Nightmares troubled him, waking and sleeping - and one bad dream conjured up another, running from box to box to release its fellows. The world around him seemed to have become equally mad and hateful. The newspapers were full of stories of grotesque violence and unnatural crimes. He knew neither how to go on nor what to do to bring these horrors to an end.
