Passing over a whole host of minor names in the list of Greek authors, we may venture upon a few facts in connection with the Latin writers. Virgil would, of course, come at the head of this list; but the examples which came under Dr. Harwood's notice have no commercial value indicated. George III. gave L17 6s. 6d. for the very fine copy of the first Horace (about 1472) in Dr. Askew's sale--a fairly good example is now priced at L50--whilst the first commentated edition of this author, Milan, 1474, has advanced from 9-1/2 guineas to 30 guineas; it is exceedingly rare, particularly the first of the two volumes. The first Aldine Horace (1501) has gone up from L2 5s. to L15, and other editions from the same press have about quadrupled in value. Of the first edition of Ovid's 'Opera' (1471) only one copy is known, and the second, Bologna, 1480, is scarcely less rare, and certainly not less valuable, than the first. Dr. Harwood prices a very fine copy at L10 5s., or about a third of its present value. The first dated edition of Valerius Maximus was printed by Schoeffer at Mentz in 1471, but is apparently not a very popular book with collectors, for whereas in 1775 a beautiful copy was valued at L26, its present price is only L28. A much more popular book, Seneca's 'Tragoediae,' printed about 1475, has advanced from 4-1/2 guineas to L18, or, an exceptionally good copy bound by Bedford, L25. Although for several centuries one of the most popular of books, some of the earlier editions of Pliny's 'Historia Naturalis' do not keep up their price. The second edition, Rome, 1470, which is rarer than the first--issued at Venice the year before--may now be had for 12 guineas. The British Museum copy of the first edition cost the nation L43 in 1775. The edition printed by Jenson at Venice in 1472 is, however, much sought after, for it is a very beautiful book, with a splendidly illuminated border on the first page of the text. The British Museum copy cost at Dr. Askew's sale L23, whilst Mr. Quaritch quotes an example at L140; but, then, the latter copy is printed on vellum, which makes all the difference. Silius Italicus is not by any means an author whose work is at present much studied, but the first edition of his 'Opera' (1471) is a book worth mentioning, because for beauty and grace it is unsurpassed by any of the works ever published by the first Italian printers, Sweynheim and Pannartz. The British Museum copy cost in 1775 L13 2s. 6d., whilst it is now worth about L25. The superb copy in the British Museum of the _editio princeps_ Juvenal and Persius (printed at Rome about the year 1469) cost the country 13 guineas; a first-class example is now valued at L12. On the other hand, the Aldine edition of Martial's 'Epigrammata' (1501) has gone up in value from 2 guineas to L10, or even L17 10s., according to condition. The first edition of Justin (printed at Venice, 1470) has declined, for the British Museum
