gratified the curious in bibliography. In the former work the books are described alphabetically, which perhaps is the better plan: in the latter, they are differently arranged, with an alphabetical index. The latter is perhaps the more valuable of the two, although the former has long been a great favourite with many; yet, from Freytag's own confession, he was not then so knowing in books, and had not inspected the whole of what he described. They are both requisite to the collector; and their author, who was an enthusiast in bibliography, ranks high in the literature of his country. In the last place we may notice the _Florilegium Historico-Criticum Librorum Rariorum, cui multa simul scitu jucunda intersperguntur_, &c., of DANIEL GERDES; first published at Groningen, in 1740; but afterwards in 1763, 8vo., at the same place, the third and best edition. It was meant, in part, to supply the omission of some rare books in Vogt: and under this title it was published in the _Miscellaneae Groninganae_, vol. ii., and vol. iii. This work of Gerdes should have a convenient place in every bibliographical cabinet. I will close this attempt to supply Lysander's omission of some very respectable names connected with bibliography by exhorting the reader to seize hold of a work (whenever it comes across him, which will be rarely) entitled _Bibliotheca Librorum Rariorum Universalis_, by JOHN JACOB BAUER, a bookseller at Nuremberg, and printed there in 1770, 8vo., two vols.; with three additional volumes by way of Supplement, 1774-1791, which latter are usually bound in one. It is an alphabetical Dictionary, like Vogt's and Fournier's, of what are called rare books. The descriptions are compendious, and the references respectable, and sometimes numerous. My copy of this scarce, dear, and wretchedly-printed, work, which is as large and clean as possible, and bound in pale Russia, with marbled edges to the leaves--cost me 5_l._ 5_s._]
