d. Now and then, alas, the conscience of man
takes up a burthen so heavy in horror that it can be thrown down only
into the grave. And thus the essence of all crime is undivulged.

Not long ago, about the closing in of an evening in autumn, I sat at the
large bow window of the D----- Coffee-House in London. For some months
I had been ill in health, but was now convalescent, and, with returning
strength, found myself in one of those happy moods which are so
precisely the converse of ennui--moods of the keenest appetency, when
the film from the mental vision departs--the [Greek phrase]--and the
intellect, electrified, surpasses as greatly its every-day condition,
as does the vivid yet candid reason of Leibnitz, the mad and flimsy
rhetoric of Gorgias. Merely to breathe was enjoyment; and I derived
positive pleasure even from many of the legitimate sources of pain. I

with minute interest the innumerable varieties of figure, dress, air,
gait, visage, and expression of countenance.

By far the greater number of those who went by had a satisfied
business-like demeanor, and seemed to be thinking only of making their
way through the press. Their brows were knit, and their eyes rolled
quickly; when pushed against by fellow-wayfarers they evinced no symptom
of impatience, but adjusted their clothes and hurried on. Others, s
