Notices to Correspondents.

We are compelled to postpone until next week several Notes on Books and Notices To Correspondents.

If Mr. Kerslake will send the extract from his catalogue which illustrates the corrupted passage in Childe Harold, "Thy waters wasted them," &c., we will give it insertion in our columns.

J. W. T. Thanks. Your hint shall not be lost sight of.

E. R. (Dublin). Erastianism is so called from Erastus, a German heretic of the sixteenth century. (See, for farther particulars, Hook's Church Dictionary, s. v.)

A Priest. We do not like to insert this inquiry without being able to give our readers a specific reference to some paper containing the advertisement; will he enable us to do so?

A. B. (Glasgow). This Correspondent appears to have fallen into an error; on reference he will find ether not washed is recommended (Vol. vi., p. 277.); 2ndly, if he varnishes his pictures with amber varnish (Vol. vii., p. 562.) previous to the application of the black varnish, which should be black lacquer and not Brunswick black, then he will succeed. Courtesy demands a reply; but we must beg a more careful reading of our recommendations, which will save him much disappointment.

Photo-Inquirer. Restoring Old Collodion.—The question was asked in a late Number. Mr. Crookes being a practical as well as scientific photographer, we hope to receive a solution of the Query.

Index to Volume the Eighth.—This is in a very forward state, and will be ready for delivery with No. 221. on Saturday next.

"Notes and Queries." Vols. i. to vii., price Three Guineas and a Half.—Copies are being made up and may be had by order.

"Notes and Queries" is published at noon on Friday, so that the Country Booksellers may receive Copies in that night's parcels and deliver them to their Subscribers on the Saturday.
