Mr. Andrew Lang is not only a distinguished bibliophile, but a prolific writer on the subject of books. He is understood to have an extensive library of an exceedingly miscellaneous character. He has an especial liking for books which bear the traces of former distinguished owners. He himself has pointed out that, 'as a rule, tidy and self-respecting people do not even write their names on their fly-leaves, still less do they scribble marginalia. Collectors love a clean book, but a book scrawled on may have other merits. Thackeray's countless caricatures add a delight to his old school books; the comments of Scott are always to the purpose; but how few books once owned by great authors come into the general market. Where is Dr. Johnson's library, which must bear traces of his buttered toast? Sir Mark Sykes used to record the date and place of purchase, with the price--an excellent habit. The selling value of a book may be lowered even by a written owner's name, but many a book, otherwise worthless, is redeemed by an interesting note. Even the uninteresting notes gradually acquire an antiquarian value, if contemporary with the author. They represent the mind of a dead age, and perhaps the common scribbler is not unaware of this; otherwise he is, indeed, without excuse. For the great owners of the past, certainly, we regret that they were so sparing in marginalia. But this should hardly be considered as an excuse for the petty owners of the present, with "their most observing thumb."' Mr. Lang is the lucky owner of a copy of Stoddart's poem, 'The Death Wake' (1831), that singular romantic or necromantic volume, which wise collectors will purchase when they can. It is of extreme rarity, and the poetry is no less rare, in the French manner of 1830. On this specimen Aytoun has written marginalia. Where the hero's love of arms and dread of death are mentioned, Aytoun has written 'A rum cove for a Hussar,' and he has added designs of skeletons and a sonnet to the 'wormy author.' 'A curse! a curse!' shrieks the poet. 'Certainly, but why and wherefore?' says Aytoun. There is nothing very precious in his banter; still it is diverting to follow in the footsteps of the author of 'Ta Phairshon.' Mr. Lang also possesses John Wilkes' copy of the second edition of 'Theocritus, Bion and Moschus,' in French, with Eisen's plates; he has Leon Gambetta's copy of the 'Journée Chrétienne,' Collet's copy of his friend Crashaw's 'Steps to the Temple,' and a copy of Montaigne, with the autograph of Drummond of Hawthornden.
