four o'clock
After his bath , he drank coffee , and again forced himself to work . By the middle of the day he felt dizzy and exhausted , but utterly disinclined to eat . He went out into the hot Strand , bought himself a necessary book , and after drinking more coffee , came back and again began to work . At four o'clock he found that he was not taking in the words . His head was burning hot , and he went into his bedroom to bathe it . Then somehow he began walking up and down , talking to himself , as Barbara had found him . She had no sooner gone , than he felt utterly exhausted .
