present at the execution of an unfortunate associate of ours: this made a
deep impression upon him; from that moment, he became thoroughly moody
and despondent. He was frequently heard talking to himself, could not
endure to be left alone in the dark, and began rapidly to pine away.

"One night, when he and I were seated together, he asked me if I never
