P. 7. _Whittier._--The poet explains that the 'lettered magnate' was his friend Fields (James Thomas, 1817-81), who edited the _Atlantic Monthly_. Among Fields's friends were Leigh Hunt, Barry Cornwall, Miss Mitford, and Dickens. Longfellow's 'Auf Wiedersehen' was written 'in memory of J. T. F.', and Whittier himself wrote some elegiac verse after his death. It may be noted that Elzevir was the name of a famous family of Dutch printers, whose books were chiefly issued between 1592 and 1681. Louis Elzevir (? 1540-1617) was the first to make the name famous. P. 9. _Roscoe._--The sale of Roscoe's library, necessary on account of financial failure, took place in August and September 1816. This Roscoe is the historian of the Medici. Washington Irving quotes Roscoe's sonnet in his reference to the incident. P. 10. _Longfellow._--These valedictory lines were written in December 1881. In the following year Longfellow died. P. 10. _Jonson._--Goodyer or Goodier (spelt Goodyere by Herrick) was the friend of Donne and of many other literary men, and he wrote verses on his own account. His father, Sir Henry Goodyer, was the patron of Michael Drayton. P. 11. _Sheridan._--Written to Dean Swift, then in London. P. 12. _Tupper._--'Next to possessing a true, wise, and victorious friend seated by your fireside, it is blessed to have the spirit of such a friend embodied--for spirit can assume any embodiment--on your bookshelves. But in the latter case the friendship is all on one side. For full friendship your friend must love you, and know that you love him.'--GEORGE MACDONALD. Compare C. S. C.'s parody on page 135; and Goethe's statement that he only hated parodies 'because they lower the beautiful, noble, and great'.
