Notices to Correspondents.
The number of Replies to Minor Queries waiting for insertion, compels us to omit our usual Notes on Books, and a number of very interesting communications.
Sch. T. C. D., who has pointed out a curious error in Disraeli's Curiosities of Literature, has been anticipated by Mr. Bolton Corney in his Curiosities of Literature Illustrated, p. 144. et seq.
A. B. R. Yes, as at present advised.
S. W. L. is assured that the communications to which he refers interest as large and intelligent a class of readers, as will feel an interest in the communication which he proposes to forward, and which we shall gladly receive.
C. D. W. T. (Jun.) is thanked: but the edition is too well known to all the Communicators, to require that he should be troubled upon the subject.
J. H. W.'s communication shall have early insertion. Our arrangements would not admit of its appearing this week.
Tyro. The anonymous Life of Queen Anne inquired after (Vol. vii., p. 108.) is a different work to that of Boyer's, and does not contain one-third the quantity of letter-press. The descriptive matter of the Metallick History has been copied from Boyer, although the plates have been re-engraved.
Mr. Brown's Letter on Mr. Archer's Services to Photography; G. H. on Difficulties in the Wax-Paper Process; and F. M. L. on the Albumen Process, are unavoidably postponed until next week.
A. B. Your suggestions will be attended to in the Notes on Photography.
Enquirer (Edinburgh). If you follow the instructions given in our former Numbers on the Collodion Process, you must meet with success. The deposit in negatives is often much blackened by adding an increased proportion of acetic acid to the pyrogallic solution—say two drachms to the ounce, so that the solution shall be one-fifth of acetic acid. A long exposure often weakens a negative; and, during the recent fall of snow, thirty seconds has produced an effective printing negative, whilst three minutes' exposure has given a negative picture so transparent as to be useless.
E. F. (Sheffield). It is only in converting a positive picture into a negative one, or in increasing the powers of a feeble negative, that the bichloride of mercury is recommended to be used. A perfectly good printing negative will be procured by following the instructions we have given in our former Numbers. Dr. Diamonds's Photographic Notes will treat fully upon this subject.
Our Sixth Volume, strongly bound in cloth, with very copious Index is now ready, price 10s. 6d. Arrangements are making for the publication of complete sets of "Notes and Queries," price Three Guineas for the Six Volumes.

PHOTOGRAPHY.—XYLO-IODIDE OF SILVER, prepared solely by R. W. THOMAS, has now obtained an European fame; it supersedes the use of all other preparations of Collodion. Witness the subjoined Testimonial.
"122. Regent Street
"Dear Sir,—In answer to your inquiry of this morning, I have no hesitation in saying that your preparation of Collodion is incomparably better and more sensitive than all the advertised Collodio-Iodides, which, for my professional purposes, are quite useless when compared to yours.
"I remain, dear Sir,
"Yours faithfully,
"N. Henneman.
Aug. 30. 1852.
to Mr. R.W. Thomas."
MR. R. W. THOMAS begs most earnestly to caution photographers against purchasing impure chemicals, which are now too frequently sold at very low prices. It is to this cause nearly always that their labours are unattended with success.
Chemicals of absolute purity, especially prepared for this art, may be obtained from R. W. THOMAS, Chemist and Professor of Photography, 10. Pall Mall.
N.B.—The name of Mr. T.'s preparation, Xylo-Iodide of Silver, is made use of by unprincipled persons. To prevent imposition each bottle is stamped with a red label bearing the maker's signature.
TO PHOTOGRAPHERS.—MR. PHILIP DELAMOTTE begs to announce that he has now made arrangements for printing Calotypes in large or small quantities either from Paper or Glass Negatives. Gentlemen who are desirous of having good impressions of their works, may see specimens of Mr. Delamotte's Printing at his own residence, 38. Chepstow Place, Bayswater, or at
MR. GEORGE BELL'S, 186. Fleet Street.
ROSS'S PHOTOGRAPHIC PORTRAIT AND LANDSCAPE LENSES.—These lenses give correct definition at the centre and margin of the picture, and have their visual and chemical acting foci coincident.
Great Exhibition Jurors' Reports, p. 274.
"Mr. Ross prepares lenses for Portraiture having the greatest intensity yet produced, by procuring the coincidence of the chemical actinic and visual rays. The spherical aberration is also very carefully corrected, both in the central and oblique pencils."
"Mr. Ross has exhibited the best Camera in the Exhibition. It is furnished with a double achromatic object-lens, about three inches aperture. There is no stop, the field is flat, and the image very perfect up to the edge."
Catalogues sent upon Application.
A. ROSS, 2. Featherstone Buildings, High Holborn.
