This amusing bibliographical squib is written by "Carolus Henricus Hartshorne," in whose hand the memorandum of the number of copies printed is given on the fly-leaf. It appears from this that only twenty were printed, and probably in a private manner for presentation. The spelling and printing are equally ancient in style, and the whole discourse, ending with the poem, runs upon black letter and other antique lore. HARTZHEIM.
