NOTE. I regret that some of the illustrations are not brought out as fully and distinctly 

 as they ought to have been, and that the shadows upon many shade so deeply. Had the plates 

 been received in time, the defective ones wonld have been corrected, but the book was ready 

 for binding long before their receipt, and the work could not be delayed longer.
