ten at night
That done , we gradually began to settle down and to accommodate ourselves to our new surroundings . Holmes was certainly not a difficult man to live with . He was quiet in his ways , and his habits were regular . It was rare for him to be up after ten at night , and he had invariably breakfasted and gone out before I rose in the morning . Sometimes he spent his day at the chemical laboratory , sometimes in the dissecting-rooms , and occasionally in long walks , which appeared to take him into the lowest portions of the City . Nothing could exceed his energy when the working fit was upon him ; but now and again a reaction would seize him , and for days on end he would lie upon the sofa in the sitting-room , hardly uttering a word or moving a muscle from morning to night . On these occasions I have noticed such a dreamy , vacant expression in his eyes , that I might have suspected him of being addicted to the use of some narcotic , had not the temperance and cleanliness of his whole life forbidden such a notion .
