I HAD INTENDED TO DEDICATE THIS BOOK TO
WILLIAM PARKER FOULKE,
Of Philadelphia,
To whom I am indebted
for all that a powerful intellect and
a generous friendship could do, to give practical
shape to my plans, and to insure success to an enterprise
in which I had embarked, with the simple advantage of an aim,
and with no better guide than the impulse of youth: but
since it is denied me to pay that tribute of my
admiration to one of the noblest of men,
I now inscribe it to his
MEMORY.
