"In Osborne's shop-catalogue for 1749, No. 5954, occurs the 'Catalogue of the late E. of Oxford's library, as it was purchased, (being the original) inlaid with royal paper, in 16 vols. 4to. with the prices prefixed to each book--pr. 10. 10. 0.--N.B. There never was any other copy of this catalogue with the prices added to it.'--The same article, at the same price, is repeated in his cat. for 1750, No. 6583, and for 1751, No. 6347--after which, being discontinued in his subsequent cats. it was probably sold. Qu'y. to whom and where is it now?"--Richard Heber, c. 1811. The first of the above notes is copied from _Letters written by eminent persons_, London [Oxford], 1813. 8o. The second note, which concludes with a _query_, forms part of some manuscript memoranda, now in my possession, on the matchless library to which it refers. BOLTON CORNEY. ACCURACY OF PRINTING. Much of the _copy_ forwarded by the contributors to "NOTES AND QUERIES" contains quotations from old books; which I presume are accurately given, without alteration of spelling or punctuation. The difficulty is this; that the printer, or perhaps even the editor, may sometimes alter what he supposes to be a _contributor's_ error of copying. Thus, in Query 93. (Vol. iv., p. 151.), there is _medulla grammaticæ_, where I wrote _grammatice_, as in my authority: but the vile punctuation of the subsequent extract (which is also that of the original) is duly preserved. It would be desirable to have some symbol by which to call attention to the fact that some glaring error is real quotation, and is to be preserved in printing. For example, an indented line (~~~~) drawn under the words in question, or at the side, would warn the printer that he is not to correct any error, however gross. If you would suggest this, or any other method, and request your contributors generally to adopt it, an increased degree of confidence in the quotations would result.
