skill, then the lady will be able together picture at a cheaper rate. If the firm in question would further oblige, by not charging for their assistant’s time and work, the lady would be better off still. But, unfortunately, that is just what photographers, and our correspondent among the number, will not do; they do not “ lend ” their negatives or their brains, and hence the comfortable arrangement in question does not come to pass. We think “ A Photogra pher ” may well afford to rest and be thankful.— En. P. N.] OXALATE DEVELOPER. DEAR Sir,—I have tried nearly all the various formul®, both alkaline and iron, in developing gelatine dry plates; and, in my opinion, Dr, Eder’s is by far the simplest and most efficacious. Having neither French weights nor mea sures, I made the two following solutions :— A. Oxalate of potash... 4 ounces, 80 grain, cost Is. Od. Distilled water ... 17} ounces, cost (say) Os. Id. B. Sulphate of iron ... 1 ounce, 5 dr. cost (say) Os. 0d. Distilled water ... 5} ounces cost (say) Os. 0±d. Sulphuric acid ... 3 drops Total cost, 23 ounce solution (say) Is. 2d. I poured one ounce of B, into a developing glass, and then added three ounces of A; with the four ounces of solution thus obtained I developed twelve half-plates. The developer worked rapidly, and for the cost of about twopence I obtained twelve negatives rivalling any that could be obtained by the wet process. I forward a sample.—I am, faithfully yours, Chas. D. Davies. 15, Lee Park, Lee, S.E. Aroceedings Of Societies. Edinburgh Photographic Society. The ordinary monthly meeting of this Society was held at 5, St. Andrew Square, on the evening of the 7th inst., Mr. John Lessees, President, in the chair. The following three gentlemen were unanimously admitted ordinary members:—Mr. Chas. A. Stitt, Mr. Arthur P. Lawrie, and Mr. Andrew Burnet. Mr. Frank P. Moffat read “ A few Remarks on the Work ing of Gelatine Plates in the Studio,’’ which was followed by an interesting discussion, in which Messrs. Lessels, Mathison, Alex. Nicol, Burton, Anderson, Airde, and Balmaine took part, after which a contribution from Mr. Andrew Pringle (now of Sorrento) was read by Mr. Forgan. The President next translated a communication regarding the forthcoming photographic exhibition in Ghent, and inti mated that as he purposed being in Ghent on the 20th of May, he would be happy to relieve of all trouble and expense any members who intended to exhibit, by taking charge of their pictures, and personally delivering them into proper hands. Mr. Mathison exhibited two varieties of instantaneous shutters, after which the usual votes of thanks terminated a most interesting evening. Glasgow Photographic Association. A meeting of this Society was held in the Religious Institution Rooms, Buchanan Street, on Monday evening, April 5th, Mr. John Urie in the chair. The minutes of previous meeting being read and approved of, the business of the evening, viz., “ The nomination of office bearers for next session,” was then proceeded with. Presidents—Messrs. J. J. Long, Parker, and Urie. Vice-Presidents—Messrs. A. Robertson, J. Bowman,Paton, and Dodds. Secretary—Mr. W. C. Ramsay. Treasurer—Mr. Geo. Bell. Auditors—Messrs. Parker and Mactear. Council—Messrs. Reid, Morran, McLillan, Leask, Gardiner, Cutting, Skinner, G. Mason, J. Fergus, Gilfillan, S. Alexander Stirling, and Dr. Fairlie. There beipg no other business, a vote of thanks to the Chair man brought the meeting to a close. Jas. McGhie, Hon. See. West Riding or Yorkshire PHOTOGRAPHIC Society. The ordinary meeting of the above Society was held at the Market Tavern, Bradford, on the 6th inst., at 7. 30 p.m., Mr. Passingham in the chair. The forepart of the evening was devoted to a conversational discussion on dry plate work, after which Mr. Crosthwaite read a paper entitled “ Stray Thoughts ” (in our next). Mr. Bridges exhibited a large lantern for dry plate work, the sides of which were covered with a canary-coloured paper which, thuogh giving a splendid light to work by, effectually cut off all injurious rays. The lamp was tested by several of the members developing plates by its light, and the opinions as to its success were unanimous. Mr. Bridges read a short paper on “ Canary Medium v. Ruby Glass”(in our next), after which the meeting became again of a conversational character, and was shortly after adjourned. 0l Gurxesgondenis. Dry’ Plate.—See illustration this week ; there should be a right angle chimney into which the inner tube loads ; you can see this in the wood cut. W. B.—There is no doubt hyposulphite in the mount; had the spots been duo to the gilt metal, a tiny black speck would have appeared in the centre ; a magnifier does not show these. G. Day.—Hydrogen is usually made by the action of sulphuric acid on zinc. We do not know what you want the gas for, but if in large quantities, it may be economically obtained by passing steam over hot iron turnings. Let us know what you want it for. A Beginner.—1. Where liquids are concerned, fluid ounces are understood, the pint containing twenty; if you are buying a graduated measure, we advise you to get one divided into cubic centimetres, which is to be had at any dealer’s. No. 2. The swing-back will not do away with distortion in architectural views, but it permits you to humour the object in a great measure; the swing-back allows you to bring into or throw out of focus top or bottom of the picture, and thus permits you to focus the most important part thereof. Studio.—We are not sure; it may be one of Ross’s portrait lenses, but Mr. Blanchard would tell you, no doubt, if you wrote him. A well-lighted drawing-room would answer very well for many purposes j but we do not think photographers can do without their studios just yet. Captain Turton.—You will find that— Double chloride of gold and potassium ... 1 part Chalk ... 2 to 3 parts Water 1,000 „ will give you a very good toning bath, and is, we believe, the one you refer to. We are glad to hear of your success with the oxalate developer. For ourselves, we always employed dis tilled water, but if your hard water is good, there can be little objection to it. The intensifier you refer to is certainly one of the best. ENLARGER.—1. Yes. 2. You do not say how the canvas is to be sensitized; gaslight will only do in the case of a gelatino- bromide film. For an iodide developing process you would want a stronger light. 3. A common deal box would do for making an improvised camera. Tiios. McCann.— 1. Much quicker. 2. Yes. 3. See leader in Photographic News for April 9th, as also “ Topic ” for next week; these will give you all the information you want on this head. 4. Paint in distemper; greys of a brownish or drab tint are most suitable. 5. Your collodion should not have suffered in a year. 6. The gelatine you send would be suitable. Thank you for your kindly expressions. P.—Any well-known apparatus maker could supply you, no doubt, for many photographers avail themselves of combination printing. Your idea of combination is a happy one, and should bring grist to the mill. Mr. B. J. Edwards patented a very clever arrange ment some eight years ago. P. Mitchell and Co.—Wo regret to receive your letter, but we have not yet had the specimens you write about. Why not do the transfers yourself? The operations are not difficult, and you can improvise a camera very easily by working in a dark room. The main difficulty is in toning, and if you employ iridium and gold instead of ordinary toning solution, this is overcome. T. Barnes.—Follow Mr. England’s advice. A pound of the best seed lac is put into a quart bottle of methylated spirit. The lac is shaken up from time to time, but the solution is not heated. After two or three days the spirit will have taken as much lac as is necessary, and the clear liquid is poured oft'. The residue may either be thrown away, or employed again with frosh lac. Hypo.—A dilute solution of iodine and starch will do all you re- ] quire. See “Topic” of the 9th April,
