about twelve o'clock
When I came back , he was in bed with Mary ; and she , dear child , had her arms around his neck , and was trying to comfort him ; and would you believe it , he went off to sleep , and slept in that way for a long time . The doctor came , and when he saw how it was , left some medicine for him , and went away . I was in such hopes that he would sleep it all off . But about twelve o'clock he started up , and sprung out of bed with an awful scream . Poor Mary ! she too had fallen asleep . The cry wakened her , and frightened her dreadfully .
