[August 7, 1885. to repeat its English Ounces. 3 20 to water. Qroceedings of Societtes 1 5 Grains. 31 42 Drams. 2 7 4 1 6 4 London and PRovIXCLAL Photoobaphic Association. A meeting of thia Society was held on Thursday, the 30th ult., Mr. A. Cowan in the chair. An interesting discussion on positive printing by the gelatino- chloride of silver process was initiated by Mr. A. L. Henderson, who showed a number of transparencies, made according to the formula recorded on page 398, and that gentleman found it possible to utilize discoloured emulsions by treating them with an excess of chloride, which excess, after adding more gelatine, was removed by washing ; the usual proportions of citrate or acetate could then be added. Another series of transparen cies was shown by Mr. H. S. Starnes, some of which had been printed on citro-chloride emulsion plates, the silver having been previously converted into an oxide, and others, wherein a mix ture of acetate and chloride, prepared from silver carbonate, had been used; these latter examples, untoned, were exceedingly rich in colour, but some toned specimens were disappointing. The general opinion appeared to be that for the purposes of reproduction or lantern work, toning would not be necessary. It was stated that citrate gave a blacker image than acetate, but lost much vigour in the toning bath, and one half at least, NLANCHESTEN Amateur Photographic Society. A number of the members have had an excursion to Hawkstone near Shrewsbury, under the leadership of Mr. S. F. Flower. On arriving at Hodnet, cameras were quickly unpacked, and shots fired up the quaint village street. Proceeding up the street, more plates were exposed on the black and white cottages and Amateur PIoTOGRAPIIIO Association. A council meeting was held on July 27th at 25, Old Bond Street, Lieut.-General the Kight Hon. the Lord de Kos in the chair. The minutes of the last meeting having been read and con firmed, the following members were elected:—W. Gaddum, Rev. E. Raste, J. P. Holmes, H. Favarger, and Ludwig G. Barber. The Secretary then laid before the meeting prints from the negatives which had been sent for the current year ; but it was found impossible, owing to the large number contributed, to make the awards, and the decision respecting the prizes was therefore deferred till the next meeting. A number of portraits recently taken by Mr. Bassano, by order of the Council, for the Museum series, were submitted by the Secretary for approval ; they included portraits of H.S.H. Prince Edward of Saxe-Weimar, Mr. James Abernethy (Pres, of the Institute of Civil Engineers), the E irl of Scarborough, Mr. Sant, R.A., Mr. Benj. Scott (City Chamberlain), Lord Sherbrooke, Mr. Scharf (Keeper of the National Portrait Gallery), Mr. Thomas Salt, M.P., Sir Samuel Scott, Bart., the Marquis of Abergavenny, and others. Mr. Bassano showed the Council the gallery and rooms which he proposed to set apart for the use of the Society, and for the exhibition of their pictures, and all present expressed their entire satisfaction with Mr. Bassano’s arrangements. A telegram was received from Mr. Walter Wood, the Manager of the Standard, expressing his regret, owing to absence from England, at being unable to be present. DULLING METAL FOR PHOTOGRAPHING. Dear Sir,—Can you tell me of a good mixture for " dulling ” the surface of cast-metal ? 1 have tried one which acts indifferently well, composed of gold size, turpentine, and the required quantity of white lead and black ; but a slight glaze occurs. Perhaps some of your correspondents have an acquaint ance with such work as photographing cast-metal goods; if so, I should much value a recipe for the treatment, so as to secure a dull surface.—I am, yours truly, R. B. Smith. appears, which I do not think will be very soon.—I remain, yours obediently, F. H. Carter. A.—Pyro.. Sulphite of ammonium Water B.—Bromide of ammonium Ammonia, -880 Water For use, take 1 dram 8 m. each FERROUS OXALATE VERSUS PYRO AND • HYDROKINONE. Dear Sir,—In reply to Charles F. Coombe’s query, under this heading, I beg to reply : — 1st. Supposing we are developing quarter-plates, using about 2 ounces of mixed developer in the dish, a batch of about a dozen may be developed without any serious loss in developing power being noticeable. 2nd. A sufficient quantity of sulphate of copper (to be added to the ferrous sulphate solution) will be about 10 grs. to the pint. 3rd. Sixty grains of dry powdered ferrous sulphate will dissolve in 1 oz. of saturated solution of potassic oxalate (neutral) without producing a precipitate. S. BOrTONE. ■ or even two-thirds, of the silver used should be combined with an organic salt rather than a chloride. The Chairman hoped the process would receive further atten tion, as he believed there was still something to get out of it beyond their present knowledge. In reference to the mixture of silver citrate and chloride, he had obtained a rich chocolate brown by using equal parts of each. Mr. Henderson remarked that the power of modifying the proportion of chloride in these emulsions allowed of results being obtained which could not be done in any other way; as an instance, a large proportion of chloride gave thin images, and a small proportion great density. The following question was then read :—“Are there any white enamel plates in the market cheaper than opal ? ” It was said that a ferrotype plate coated with a white com position was an er tide of commerce. Mr. Skene (Columbo) spoke of the annoyance caused by insensitive marks on some commercial plates, and which, he believed, was due to the racks used in drying. Mr. A. Mackie had met with several kinds of stains in com mercial plates, which were attributable to an inefficie nt method of drying. Mr. Henderson used cane racks, which did not stain the plates; still, he thought that an emulsion insufficiently washed was often the cause of these markings. Mr. A. Haddon exhibited a remarkable case of red and green fog, in which the image was of a deep ruby colour. Another plate of the same batch, developed without bromide, and with very little ammonia, yielded a clear negative, which pointed to bro mide being one of the causes of green fog. The Chairman was of opinion that a large proportion of bromide would have given a clear negative. Another short discussion anent the rise and fall shutter between lenses, was then opened by Mr. W. B. B. Wellington, who found that an opening of one-sixteenth of an inch at the bottom was sufficient to illuminate all but the four corners of a plate. The Chairman thought that meant unequal illumination, because, had that opening been in the centre of the lens, the corners of the plate would have obtained the advantage. The shape of a stop would not alter the image, but the position of the stop did make a difference. The discussion was continued by the Chairman, Messrs. Mackie, Wellington, Haddon, Collier, and Henderson. . — 3} ounces of Perhaps a little less of the B, or the quantity of water may be somewhat increased if needful; for, as usual, this developer, like all others, requires to be mixed “ with brains,” of which all photographers worthy of the name keep a stock on hand. It seems to serve equally well with all commercial plates; at least, I have tried it with Edwards’, Paget, and the Imperial with perfect success. I shall discard the use of all others for this till a better “parts, ' the understanding of which does not come by nature, it may be worth while equivalent:—
