March 20, 1885 J THE PHOTOGRAPHIC NEWS. 189 a commercial article composed [of gelatine and glycerine as a backing for plates giving halation with subjects of a black-and- white character. The article, which is made in sheets of vary ing thickness, is easily squeezeed on the back of a glass plate, and as easily removed. He (Mr. Cowan) found it better than carbon tissue and other backings, and illustrated his remarks with a serifs of negatives. Mr. W. H. PRESTWICH thought the test was a severe one, and although halation was not entirely prevented in the examples shown, it was considerably mitigated. The Chairmax suggested Fol’s method of soaking carbon tissue in glycerine to obtain a similar flexibility and adhesiveness. Mr. J. B. B. Wellington then gave a practical illustration of the capabilities of his new dissolving carrier, a description of which was given in our last report of this Society. He passed about 160 choice transparencies through the lantern. The whole of these pictures were shown on the screen without any hitch whatever, dissolver acting perfectly. Mr. W. J. Simpson was elected a member of the Association, after which it was announced that a number of forms of tender for the right of taking photographs at the International Inven tions Exhibition had been sent for distribution among the members.

H. Williams were elected members of the Association. Mr. Croker exhibited a half-plate camera, of ordinary make, to which he had adapted a swing-back in a very simple and inex pensive manner. Mr. A. W. Beer (assisted by Mr. A. W. Cornish, who manipu lated one of Hughes’ new Pamphengos 1 interns) then read a paper entitled, “ A Few Stray Sheti in Ireland ” (see page 187). In the course of the paper, a large number of excellent trans parencies, reduced from negatives taken by the above-named gentlemen, were thrown upon the screen, and frequently elicited deserved admiration and applause. CANTTRIDOE University PIOTOGnArIIC Society. A HIGHLY successful exhibition was held under the auspices of the above Society on Thursday, March 12th, in the rooms of Mr. W. N. Shaw, Emanuel College. Over 100 negatives, prints, and transparencies were exhibited by members, many of them being of great merit, both artistic and technical. Before the exhibition, a general meeting of the Society was held, Mr. Shaw, President, in the chair ; and it was decided that similar exhibi tions should be held every October and Lent Terms, and also a larger and more public one in the May Term. Glasgow PIOTOGRAPHIC Association. The usual monthly meeting was held on Tuesday, the 10th inst., Mr. Hugh Reid in the chair. After the approval of the minutes, the following new members were admitted :—Mrs. Ramsay, Miss Mary Thom, Messrs. Robt. Goodier, Hugh Reid, G. Y. Armour, Robt. Cairns, W. B. T. Halley, Hugh H. Smiley, Jas. Brown, and Peter Beattie. Mr. Wm. Goodwin read a short paper on “ Aids to Correct Exposure "(see page 180), and explained Burton's table. Mr. Goodwin showed a small box made like Woodbury’s photometer, and filled with Morgan’s paper, and demonstrated the change of colour by exposure to magnesium ribbon. A number of members then showed interesting and novel apparatus, including many improvements made by themselves, and this brought the meeting to a close. Edinburgh Photographic Society. The fifth meeting of the session was held on Wednesday even ing, 4th March, Mr. Norman Macbeth in the chair. The minutes of last meeting having been road and approved, the following gentlemen were admitted as ordinary members of the SocietyMessrs. 1). Guthrie, T. G. Whaite, John Drum mond, Walter J. H. Cumming, D. Taylor, D. Cuthbert, J. Fal coner King, F.C.S., and John Scott. Mr, A, B. Stewart read a paper on “ The Faculty of Observa tion, or Commonplace Knowledge in Picture-Making ” (see page 181). Mr. TaMkin said that many a good picture had been spoiled for want of a little of that common-place knowledge about which Mr. Stewart had spoken, and it would be well if photographers would exercise a little more of that faculty ot observation so necessary in making really good work. Mr. Balmain stated that he would be almost frightened to submit any pictures of his for Mr. Stewart to pull to pieces; nevertheless, what Mr. Stewart had insisted on was perfectly correct. Mr. Howie thought that it was of great importance that photographers should be careful in making their observations before firing off their plates ; indeed, they could not be too care ful. It was a great mistake, although a very common practice, for photographers to go out and fire away at the first thing that came before them. If they would only exercise the faculty of observation, and carefully note the lighting and composition of their subject, and ascertain the best point from whence to take it, this would tend ta make them much more successful as far as the pictures were concerned. The President said that he should not be satisfied with what merely strikes him at the first glance, but should work round it and see it under every possible condition of light. There was a very simple plan that would greatly aid photographers in examin ing pictures, namely, to have a little opening cut in a piece of blackened card, and find the picture by this, turning it in every direction until the best point of view was found. This was a method that never failed to produce the finest effects. Mr. BKEBNER then gave a practical demonstration of his new method of developing by means of a copper plate immersed in contact with the exposed negative in various chemical media. In answer to a question by Dr. Thompson, Mr. Brebner stated that he could not quite explain the chemical effect of the various compounds he had used ; that he got very similar results with ammonia mixed with honey, glucose, dextrose, and various other organifiers. Mr. Henderson thought there seemed to be something in this process capable of development, that the action seemed to him to be electric, and he suggested that experiments might be made in the way of coating the copper plates directly with the sensitive film, and exposing and developing the image there, and the image might possibly be etched on the copper afterwards by means of sulphuric acid or perchloride of iron. Mr. Halliday exhibited a machine which he had used for many years for sizing paper, and which he thought might be used for coating paper with emulsions. The apparatus consisted of a wooden trough having a groove at each end. In this trough was placed a wooden roller, the axis of which worked in the grooves. The paper to be coated was rolled up on a rod exactly the same length as the trough, and which also fitted into the grooves. The weight of the roll of paper kept it in close contact with the under roller. A quantity of emulsion was then poured into the trough sufficient to nearly cover the wooden roller, and on the paper being drawn off it actuated the wooden roller, which lifted a layer of emulsion and brought it in contact with the paper, which came off perfectly and evenly coated with emulsion. Mr. Turnbull reported that, as commissioned by the Council, he had attended a meeting of the London and Provincial Photo graphic Association on Thursday night last, and in the name of the Society had presented to that Association copies of the three last presentation prints, and he had been requested to convey to the Society the hearty thanks of the Association for these prints, which had been much admired. It was stated that Mr. Turnbull while in London had selected a series of slides entitled "Devonshire Illustrated,” to be used at the next popular meeting. Newcastle-on-Tyne and Northern Counties Photo- GRAPIIIC Association. The ordinary meeting was held on Wednesday evening, the 11th inst., the President (Prof. Herschel, M.A, F.R.A.S., &c.) in the chair. Lt.-Col. Osbaldiston Mitford and Mr. Meldrun Dawson were elected members. Mr. B. S. Proctor read a paper entitled “Lessons Derived from Pinhole Photographyt" (see page 182). Remarks were offered by the Chairman, Mr. Pae, Mr. Dodds, Mr. Gibson, and Mr. J. W. Robinson. Mr. R. Stanley Freeman followed with a paper on “ A New
