five o’clock
This last question the Professor answered with a loud and ringing `` No . '' After a moment of silence he added , in a lower tone , another `` no '' as if in answer to his own thoughts . The thermometer had gone up to thirty-seven point five ; more than one degree since the evening before . Should the fever increase , should there be danger of delirium , he would send at once , to Bocca della Verità , even before five o'clock . It did not seem probable the fever would increase rapidly , although that thirty-seven point five had a black look . He asked the invalid if the electric light troubled him . Benedetto replied that materially it did not trouble him , but that spiritually it did , because it prevented his seeing the sky , the starry night .
