Passage
the tone
true! --nervous -- very, very dreadfully nervous i had been
and am; but why will you say that i am mad? the disease had
sharpened my senses --not destroyed --not dulled them. above
all was the sense of hearing acute. i heard all things in the
heaven and in the earth. i heard many things in hell. how, then,
am i mad? hearken! and observe how healthily --how calmly i
can tell you the whole story.

what is the tone?
