I have read "Mr. RICH'S" letter with great interest, and I willingly allow that he has combated my charge of plagiarism against Pope, and discussed the subject generally with equal fairness and ability. "But yet," I think that he wanders a little from the point when he says, "the surmise of the plagiarism originates in a misconception of the terms employed by the Latin author, especially _corcillum_." Now the question, in my opinion, turns not so much on what _Petronius said_, as on what _Pope read_; i.e. not on the meaning that _Petronius gave_ to the word (_corcillum_), but on that which _Pope attributed_ to it. I cannot, without further proof, give him credit for having read the words as critically and correctly as "Mr. R." has done. I believe that he looked on it merely as a simple derivative of _cor_, and therefore rendered it "worth," i.e. a _moral_, not a _mental_ quality. C. FORBES. * * * * * QUERIES. QUERIES RESPECTING PURVEY ON THE APOCALYPSE, AND BONNER ON THE SEVEN SACRAMENTS. I beg leave to make the two following Queries:-- 1. In Bayle's very useful work, _Scriptorum Illustrium Majoris Brytanniæ Catalogus_, fol. Bas. 1559, among the writings ascribed to John Purvey, one of Wycliffe's followers, and (as Walden styles him) _Glossator_, is mentioned _Commentarius in Apocalypsin_, beginning "Apocalypsis, quasi diceret;" and Bayle adds:-- "Prædictus in Apocalypsin Commentarius ex magistri Wielevi lectionibus publicis per Joannem Purvæum collectus, et nunc per Martinum Lutherum, _Ante centum annos_ intitularus, anno Domini 1528, sine authoris nomine, Witembergæ fuit excusus. Fuit et ipse Author in carcere, ac cathenis insuper chalybeis, cum ea Commentaria scripsit, ut ex decimo et undecimo ejus scripti capite apparet. Scripsit autem Purvæus hunc librum anno Domini 1390, ut ex decimo tertio capite et principio vigesimi apparet." This account of Bayle (who is mistaken, however, about the _title_ of the work) is confirmed by Panzer; who, in his _Annales_, vol. ix. p. 87. enters the volume thus, "_Commentarius in Apolcalypsin ante Centum Annos æditus, cum Præfatione Maritini Lutheri_. Wittembergæ, 1528. 8vo." Can any of your readers refer me to a copy of this book in a public library, or in private hands?
