/ 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 : hut 



since it is denied ?ne to pay that tribute of my 



admiration to one of the noblest of men ^ 



I now inscribe it to his 



MEMORY.
