Hawk-eye Camera.—A detective camera bearing this name has been recently issued by the Blair Camera Company, and the agents for it in this country are Messrs. Taylor, Taylor, and Hobson, of Leicester and London. It possesses several features which make it valuable not only for hand use, but for occasional employment on a stand when long exposures are necessary. For this latter purpose it is furnished with an interior focus sing screen, which is accessible only when a shutter at the back of the instrument is removed, the said shutter, by the way, fastening into its place by a unique spring movement. The camera can be fitted to work with plates, with separate films, or with an Eastman roller which provides for forty-eight exposures. The focussing is brought about by a screw’ at the back, in conjunction with a sunk dial, which is marked for various dis tances under 100 feet. The camera is designed for 5 by 4 plates, so as to allow some margin for faulty direction, a fault which is, however, guarded against by the presence of a finder. The lens is a T. T. and H. 6-ineh (detective) working at//8 ; but it is provided with a sliding diaphragm plate with three open ings of varying diameter. The shutter is set by a simple winding operation without uncovering the lens, so that no extra cap or flap is wanted, and its speed can be regulated to a nicety. The camera is unobtrusive in appearance, well-made, and has no projecting knobs or studs, Corresponence. CROYDON MICROSCOPICAL AND NATURAL HISTORY CLUB (PHOTOGRAPHIC SECTION.) Sir,—I regret to find a slight error has occurred in the stylograph copy of my notes supplied to the press of the proceedings of the above Club in your last week's issue. By the omission of a single letter what should have read “a misleading and almost incorrect statement,” appeared as “a misleading and a most incorrect statement.” As I should be sorry to be guilty of any discourtesy of speech to your contem porary to whom the expression refers, I will be glad if you will publish this explanation. Harry D. Gower, April 18th. Proceedngs of Sorctics. Camera Club. On Thursday, April 16th, Dr. C. S. Patterson in the chair, Mr. J. Howson read a paper entitled “Conventionalism in Colour. ” Previous to the lecture, the Hon. Secretary handed round some early prints sent by Mssrs. Marion & Co. from the flash light negatives taken the previous week ; also one of Manson’s focussing cloths, which are made in convenient form for cover ing the whole of the camera. Dr. Patterson showed a Bain’s mask-cutter. Mr. Howson, in his paper, dwelt on the possibility and de sirability of suiting the monochrome colour of photographic prints to the special subject in each case represented, and he illustrated his points by handing round several prints on alpha paper. Criticism and discussion followed from Messrs. Horsley- Hinton, Davison, Gale, Stephens, Bright, and the chairman. On Monday, April 13 th, there was a special lantern evening at the Club, and one of the largest and most interesting collec tion of slides ever shown at the Club was brought together by members and friends. The extra meeting was appointed for the purpose of work ing off the arrears into which the lantern exhibition had fallen, owing to the period of removal into the new premises. Over 400 slides were shown—almost all new at the Club—the work of Messrs. Gibbons, Jones, Elder, d’Arcis, Noel-Cox, Carpenter, Bennet, Lawford, Laurie, Maskell, Matthews, Bright, Hughes, H. M. Hastings, Andreae, Huskisson, Burton, Cembrano, Seyd, Chang, and Fitz-Payne. On Thursday, April 30th, Mr. J. Traill Taylor will read a paper on “ Lantern Optics.” London and Provincial Photographic Association. April. 1&th.—Mr. G. W. Atkins in the chair. A demonstra tion of polarised light by Mr. J. J. Briginshaw, announced for this date, was postponed to the 30th inst., in consequence of the non-delivery of the oxygen gas. Mr. C. H. Cooke made a contribution of several platinotype prints to the album of the Association. He also exhibited some sepia platinotype prints that had been developed with a hot bath for black tones ; he was unable to detect any difference from those developed according to the sepia formula. Mr. P. Everitt drew attention to an advertisement in the journals referring to the use of ammonia with erythrosine. He questioned whether the patent referred to in the advertise ment covered the dipping process, and, further, whether the addition of ammonia was absolutely necessary. To the latter query Mr. C. H. Cooke replied, decidedly not. Mr. W. E. Debenham said he doubted whether erythrosine of the particular variety now used was suggested by the patent mentioned, as, in all probability, it was not brought out until afterwards ; and he was of opinion that the patent was not valid, from the directions given with it not being sufficient to enable it to be a working process. Mr. C. H. Cooke stated that the use of a screen was not necessary ; equally good results could he obtained without it,
