728 THE PHOTOGRAPHIC NEWS. [October 16, 1891. Oxford, for there could be no place of its size where more was done in photography, and where lanterns must be in use hun dreds of times in a year. The dark room is well fitted up, and nearly every British photographic periodical is on the table in the meeting room. Various schemes were proposed for the coming season, among which was Mr. Stanley Kent’s proposal to establish a library of lantern slides. The following officers and committee were then unanimously elected: President (for the third year)—Mr. E. A, Ryman-Hall; Vice-Presidents—Messrs. C. C. Cole, A. F. Stanley Kent, M.A. (Magdalen College), A. F. Kerry, M.A. (Exeter College), and Councillor J. H. Salter ; Hon. Treasurer—Mr. J. Minn ; Hon. Secretaries—Messrs. F. A. Bellamy, F.R.M.S., and H. Minn, 136, High Street ; Committee—Messrs. N. G. French, W. J. King, G. W. Norton, H. M. Phillipps, A. Robinson, G. A. Smith, and Rev. W. H. Price, M.A. Five names were read for membership. Sheffield Photographic Society. The annual meeting was held at the Masonic Hall, Surrey Street, on October 6th, with Mr. B. J. Taylor in the chair. The Treasurer presented his statement of accounts, which showed a considerable balance in hand. The Secretary read his report of the proceedings for the year, showing that there had been three resignations, and twelve new members. The Society was never in a more flourishing condition than at present, and the proceedings had been characterised by an amicable tone throughout. The excursions had received considerable attention and support, and had been much more numerous than for several years past. They had produced some splendid work, especially the one to Lincoln. The officers for the ensuing year were elected as follows : President—Mr. B. J. Taylor (elected for the third time) ; Vice- Presidents—Mr. G. Bromley and Mr. Thomas Frith ; Council —Messrs. Ed. Sampson, W. T. Furniss, W. V. Davy, Josh. Smith, and T. G. Hibbert ; Treasurer—Mr. Ernest Beck ; Reporter—Mr. E. H. Pearce. Lewes Photographic Society. At an ordinary meeting of this society, held at the Fitzroy Library on Tuesday week, Mr. J. G. Braden, the president, occupied the chair. The sets of prints from hand-camera negatives sent in to the quarterly competition were on view. Mr. J. Hunter Graham, a member of the Brighton Photo graphic Society, as judge, awarded the certificate to the set belonging to the hon. secretary, Mr. E. J. Bedford. The President then gave “ A Few Notes on Exposure,” and in his introductory remarks expressed the hope that all mem bers would bring with them not only their good work, but also their failures, for he thought that often more might be learnt from a failure than a success. He said to produce a perfect negative it was necessary to give the correct exposure. He had brought Watkins’ exposure meter, which he fully explained, and said that after a series of experiments he had made with the instrument, he had come to the conclusion that it was a very great help to photographers in ascertaining the exact exposure required for any subject. He showed examples exposed in accordance with the meter, which seemed to be per fect, though they were subjects which differed very widely in the time of exposure required. Mr. Percy Morris proposed, and Councillor Wightman seconded, that a Watkins’ exposure meter be given as a prize to the member who should produce the best results in some future competition, which was carried unanimously. Photographic Veneering of Furniture.—In the applica tion of photographs to cabinet-ware, Mr. J. K. France has patented the use of a substance that he calls “pyralin, or some other compound of pyroxylin.” The print is fixed by means of alcohol. It is applied to the wood to be decorated, and the surface polished by pressure on a metallic plate, or by other means. This invention has for principal object the veneering of furniture.— Wilson’s Photographic Magazine. Answers to Correspondent. All Advertisements and communications relating to money matters, or to the sale of the paper, should be addressed to the Publishers of the PHOToouAruic News, Messrs. Piper & Carter. 5. Furnival Street, London. Questions requiring a reply in this column should be addressed to Mr. John Spiller, P.O 8., 2, St. Miry’s Road, Canonbury, N. Sam.—Sticky Black Varnish. Your unfortunate experience does not admit of more than partial remedy. It will, of course, be impossible to restore the torn films, but in the event of your having any more negatives which have been treated in the same way, you should either print them through a sheet of mica, or rub them over with starch powder, which will only adhere to the tacky portions. With respect to fresh negatives and future work, you may get good results by rubbing into your present varnish some litho graphers’ Frankfort black, and then thin down with pure benzol, by which its drying properties will be vastly improved without loss of opacity. Re-Bronzing Lens Diaphragms.— Clean the worn surfaces by rubbing with a cloth moistened with dilute ammonia ; when dry, brush the metal over on both sides with a warm solution of chloride of platinum, drop them into hot water, wash well, and dry. Finally, rub them over with powdered black-lead to make them slide easily. Old Subscriber.—Bromide Enlargements to Take Oil Colours. See Messrs. Morgan and Kidd’s catalogue, page 5, for sensi tive coated canvas on wedged stretching frames ; or you may prepare your own canvas with bromide emulsion. The treat ment of a bromide paper print to make it take oil colour would be very unsatisfactory, for the coating with distemper must inevitably hide much of the photographic detail. Enquiry.—Photo-Mechanical Prints. The Direct Photo Engraving Company (Messrs. Hoffman and Co.), Barnsbury Park, N. ; The Meisenbach Company, 188, Fleet Street, E. C. ; Messrs. Husnik and Hausler (agent: F. C. Clarkson, 4, Fenchurch Avenue, E.C.). H. B.—Tremors from Passing Traffic. Before proceeding to make another move, try the method of slinging the whole apparatus, enlarging camera and copying frames, as is often done in large city establishments to overcome vibration. F. P.—Bank-Note Security. Instances have not been wanting of late to prove that chequesand some bank-notes are being tampered with, and your newspaper cutting is but another evidence of the fact. Before long a bankers’ commission may possibly be appointed, or you might at once communicate with Sir John Lubbock. Printer.—Silver Print Trimmings and Waste. The burning of albumenised paper in large quantities must always be a bit of a nuisance. The unpleasant odour might be partly mitigated by soaking with nitre or nitrate of soda solution, drying, and then setting fire to small parcels in succession. The heap of refuse or ashes thus obtained should now be fused with more carbonate of soda to recover the silver in the ordinary way. F. R. A. S.—Sun Photography. A week ago the sun’s disc showed a large group of spots in the southern zone, with a smaller single spot high above them. The Woolwich tele scope, with which our photographs were formerly taken, was furnished with a lens of fully 4 ins. aperture, and 6 ft. 5 in. focal length. The image of the sun measured, in July, exactly •7 in. diameter. The chemical and visual foci did not coincide, but differed by about two inches. Exposure was instantaneous for collodion with a quarter-inch stop, so that no clockwork or “ following machinery ” was required, the finder enabling us to keep the sun’s disc in view. For working details, see the Photographic Journal of November, 1860. The Kew results, in later times, were in every way superior, but, given a perfectly sharp negative of small dimension on a structureless film, there should be no diffi culty in enlarging to two or three diameters. Wymondham.—Flattening Albumen Prints. By passing through a rolling press, or merely dragging them, face upwards, over a sharp-edged table, the tendency of the print to curl inwards may be counteracted. With regard to the other matter, your kind letter of thanks is a sufficient reward.
