y particulars be easily ascertained relative to reprints of the
acts of the canonisation of the Seraphic Doctor in their original small
quarto shape?

(20.) To whom should we attribute the rare tract entitled _Lauacrum
conscientie omnium sacerdotum_, which consists of fifty-eight leaves, and
was printed in Gothic letter at Cologne, "Anno post Jubileum quarto?"

(21.) Where can information be met with as to the authorship of the
_Dialogus super Libertate Ecclesiastica_, between Hugo, Cato, and Oliver?
Fischer (_Essai sur Gutenberg_, 79.) traces back the first edition to the
year 1463; but I know the treatise only in the form in which it was
republished at Oppenheim in 1516.

(22.) Who was the compiler or curator of the _Viola Sanctorum_? and can the
slightest attempt be made at verifying the signatures and numbers inserted
in the margin, and apparently relating to the MSS. from which the work was
taken? One of two copies before me was printed at Nuremberg in 1486, but
the other I believe to belong to the earliest impression. It is of small
folio size, in very Gothic type, perhaps of the year 1472, without date,
place, or name of printer, and is destitute of cyphers, catchwords, and
signatures. There are ninety-two leaves in the volume, and in each page
generally thirty-three (sometimes thirty-four, rarely thirty-five) lines.
(See Brunet, iii. 547.; Kloss, 280.; Panzer, i. 193.)

(23.) By what means can intelligence be procured respecting "Doctor
Ulricus," the author of _Fraternitas Cleri_? A satisfactory reply to this
inquiry might probably be found in the _Bibl. Spenceriana_; but I have not
now an opportunity of determining this point.

(24.) A question has been raised by Dr Maitland, from whose admirable
criticism nothing connected with literature is likely to escape, as to the
meaning of the letters "P.V." placed over a sudarium held by St. Peter and
St. Paul. (_Early printed Books in the Lambeth Library_, pp. 115. 368.) Any
person who has happened to obtain the _Vitas Patrum_, decorated with the
curious little woodcuts of which Dr. Maitland has carefully represented
two, will cheerfully agree with him in maintaining the excellence of the
acquisition. In a copy of this work bearing date 1520, eleven years later
than the Lambeth volume (_List_, p. 85.), the reverse of the leaf which
contains the colophon exhibits the same sudarium, in company with the words
"Salve sancta Facies." This circumstance inclines me to ven
