EXHORTATION AGAINST THE TURKS, &c.:  of the supposed date of 1455.  This is the singular tract, of which Baron Aretin (the late head librarian of this establishment) published an entire fac-simile; and which, from the date of M.cccc.lv appearing at the bottom line of the first page, was conceived to be of that period.  M. Bernhard, however,—­in an anonymous pamphlet—­proved, from some local and political circumstances introduced, or referred to, in the month of December—­in the Calendar attached to this exhortation—­that the genuine date should rather be 1472.  This brochure is also considered to be unique.  It is a small quarto, of six leaves only, of which the first leaf is blank.  The type is completely in the form of that of Pfister, and the paper is unusually thick.  At the bottom of the first leaf it is observed, in ms. “Liber eximiae raritatis et inter cimelia bibliothecae asservandus.  F. Er.”

ARS MEMORANDI, &c.  Here are not fewer than five copies of this well known—­and perhaps first—­effort of block-book printing.  These are of the earliest dates, yet with trifling variations.  The wood cuts in all the copies are coloured; some more heavily than others; and in one of them you observe, in the figure of St. Matthew, that red or crimson glossy wash, or colour, so common in the earliest prints—­and which is here carried over the whole figure.  One of these five copies is unbound.

ARS MORIENDI.  Here are two editions, of which one copy is indisputably the most ancient—­like that in Lord Spencer’s library,[52]—­but of a considerably larger size, in quarto.  There can be no doubt of the whole of this production being xylographical.  Unluckily this fine copy has the first and last pages of text in ms.  The other pages, with blank-reverses, are faintly impressed in brown ink:  especially the first, which seems to be injured.  A double-line border is round each page.  This copy, which is bound in blue morocco, has also received injury from a stain.  I consider the second copy, which is bound in red morocco, to be printed with moveable metal types.  The ink is however of a palish brown.  I never saw another copy of this latter impression.

BIBLIA PAUPERUM. In Latin.  I doubt whether this be the first edition; but at any rate it is imperfect. In German:  with the date of 1470.  Here are two copies; of which I was anxious to obtain the duplicate (the largest and uncoloured,) for the library in St. James’s Place; but the value fixed upon it was too high; indeed a little extravagant.

The APOSTLES CREED. In German.  Only seven leaves, but pasted together—­so that, the work is an opistographised production.  This is a very rare, and indeed unique volume; and utterly unknown to bibliographers.  Each cut is about the same size, and there are twelve in the whole.  There is no other text but the barbarous letters introduced at the bottom of the cut.
