LIFE OF HENRY FUSELI. BY A. useli—so he chose to spellhis name, though hisfathers wrote it Fuessli—was born, by all accountssave his own, in the year1741, at Zurich; but ashe seldom wished to thinklike other men, so he refused to beborn according to tradition or re-gister books, and taking up a littleGerman memoir of himself, changedthe date of his birth from 1741 to1745, without adding either day or was the second of eighteen children :his name pertains to Switzerland—all bywhich that name is distinguished to Eng-land.
