The most singular bibliographic curiosity is that which belonged to the family of the Prince de Ligne, and is now in France. It is neither written nor printed. All of the letters of the text are cut out of each folio upon the finest vellum; and, being interlaced with blue paper, it is read as easily as the best print. The labor and patience bestowed upon it must have been excessive, especially when the precision and minuteness of the letters are considered. The general execution is admirable in every respect, and the vellum is of the most delicate and costly kind. Rodolphus II., of Germany, offered for it, in 1640, eleven thousand ducats, which was probably equal to sixty thousand at this day. The most remarkable circumstance connected with this literary treasure is that it bears the royal arms of England, but it cannot be shown that it was ever in that country. The book is entitled: _Liber Passionis Domini Nostri Jesu Christi cum Characteribus Nulla Materia Compositis_. _A Long Lost Book Recovered._ The book called "The Ascension of Isaiah the Prophet" had been known to exist in former ages, but had disappeared after the fifth century. During the present century Dr. Richard Laurence, the professor of Hebrew at Oxford, and afterwards Archbishop of Cassel, accidentally met with an Æthiopic MS. at the shop of a bookseller in Drury Lane, which proved to be this apocryphal book. There was something remarkable in the discovery, in a small bookseller's shop, of a book which had been lost to the learned for more than a thousand years. _The Bug Bible._ Among the literary curiosities in the Southampton library, England, is an old Bible known as the "Bug Bible," printed by John Daye, 1551, with a prologue by Tyndall. It derives its name from the peculiar rendering of the fifth verse in the 91st Psalm, which reads thus: "So that thou shalt not need to be afraid for any bugs by night." _Illuminated Manuscript Bible._ Guido de Jars devoted half a century to the production of a manuscript copy of the Bible, with illuminated letters. He began it in his fortieth year, and did not finish it until his ninetieth (1294). It is of exceeding beauty. _The Mazarine Bible._ This is so called from its having been found in the Cardinal's library. It was the first book printed with metal types, and cost $2,500. _A Book without Words._ A literary curiosity exists in England in the shape of "A Wordless Book," so called because, after the title page, it contains not a single word. It is a religious allegory devised by a religious enthusiast, and the thought is in the symbolic color of its leaves, of which two are black, two crimson, two pure white, two pure gold. The black symbolizes the unregenerate heart of man; the crimson, the blessed redemption; the white, the purity of the soul "washed in the blood of the Lamb;" the gold, the radiant joy of eternal felicity. _Wierix's Bible._
