172 THE PHOTOGRAPHIC NEWS. [Mauch 13, 1885. Coxxespondente. PHOTOGRAPHERS’ BENEVOLENT ASSOCIATION. Dear Sir,—I am glad to notice in your issue of the 6th inst., that the officers of the Benevolent Association have requested photographers who are willing to co operate with them in this matter to send in their names. Would it not be as well if the Association were to issue a circular, and send to the leading photographers in each town with the request that they would convene a meeting to ascertain the views of all interested, and to pass a resolution as to whether it should be simply a Benevolent Society, or a Benevolent and Benefit Society ? I venture to say if the latter, it would be a success. I shall be glad to do my utmost, but think the moving powers should be the employers ; the assistants will gladly respond.—I am, &c., • An Operator. ISOCHROMATIC PLATES. Dear Sir,—In reply to my short article in the News of January 16, in the matter of priority in isochromatic pro cesses, Mr. Ives, in his communication to the News, February 27, makes very strong efforts to depreciate my wet eosine process —a process not sold by me as a secret, as Mr. Ives asserts, but rewarded with a prize of honour by the Berlin Society for the Advancement of Photo graphy, and published—also to elevate his own chlorophyl process. Whether Mr. Ives has tried my process as I have described it, I don’t know ; but I know that this process is practically employed in first-rate German reproduction establishments, as Haufstaengl, of Munich, and the “ Photographische Gesellschaft,” Berlin, &c., with the best success, for plates up to 30 inches. I think that is a proof that the process is not quite so poor as Mr. Ives asserts. On the other hand, Mr. Ives tries to scoff at my first success ful experiments to get an isochromatic photograph in 1873. I beg to reply to this only, that my modus operandi has been the original for all following isochromatic processes, even for those of Mr. Ives.—Faithfully yours, Dr. H. W. Vogel. 2roceedings of Sorieties. PHOTOGRAPHIC Society of Great Britain. The ordinary meeting of this Society was held on Tuesday, the 10th inst., at the Gallery, 5a, Pall Mall East; Mr. Jambs GLAISHER, F.K.S., President, in the chair. The minutes of the previous meeting having been read and confirmed, Messrs. J. J. Ackworth, W. Noble, and J. Webster were elected members of the Society. The Chairman, after stating that there was no paper to be read that evening, invited Mr. T. Sebastian Davis to open a dis cussion upon the subject of drying gelatine plates. Mr. Davis commenced by saying that it was a matter of im portance to amateurs and those experimentalists who desired to make small batches of emulsion, that they should possess a reliable means of drying their plates within a reasonable time, and he had lately given some attention to the subject. Speaking of wooden racks in a drying box, Mr. Davis said failures often resulted through the grooves of the racks being too close together, and it was his experience that plates would not dry evenly unless they were 2 inches apart; a less distance prevented a good circulation of air. His plan gave uniformity, and he was quite sure that films evenly dried within a reasonable time obviated a number of difficulties otherwise attending the use of gelatine plates. Mr. J. CADETT, in relating his experience in drying small batches of plates, said he succeeded better when the inlet passed directly on a metal plate heated below by gas, and supplemented by another jet burning beyond the elbow in the outlet. For commercial purposes nothing was better than a room with hot- water pipes circulating through it. Mr. W. E. DEBEXHAN said it had been stated and accepted that a certain speed was essential to perfect drying of gelatine plates, the minimum being eight hours, and twenty-four hours the maximum. Those periods were, no doubt, very good ; but it did not follow that good results could not be obtained other wise. He could show plates which had been quickly dried where the heat was nearly enough to liquefy the gelatine, and they showed no signs of frilling or fog. On the other hand, he could demonstrate that slow drying was not bad, as instanced by Mr. Wellington’s transparencies, which were four days drying with out heat over calcium chloride. Cpt. Abney had succeeded with Mr. England’s plan; but when he increased the size of his plates he tried the method of admitting heated air at the top of the chamber, the outlet at the bottom serving to supply the gas jet, which was sealed from external air. Plates near the top of this box dried in three to four hours, and frilled; those near the bottom occupied four days, and were not so good as they ought to have been. He now used a coil of composition pipe in the bottom of a box fitted with the usual inlet and outlet pipes, and connected the coil to a hot-water tank outside, the heat of which was easily regulated with a small ordinary gas jet. By this means a steady heat, 80° to 85° Fahr., could be maintained, and eight hours would dry most plates ; he objected to go beyond ten or twelve hours with his plates. The dimensions of the box he gave as 4 feet long, 3 feet 6 inches high, and 3 feet broad (see page 168). Mr. W. England briefly described the construction of his box, which has been described in these columns, also in the YEAR-BooK and “ Studios of Europe.” He still used it for experimental purposes, but preferred an ordinary room for commercial work. Mr. W. BEDFORD formerly used a cupboard similar in principle to the one described by Mr. Cadett, and it acted very well. One day the door was inadvertently left open, and the plates dried in much less time ; since then he dried his plates in an ordinary room. Plates put back to back, in racks with grooves an inch and a half apart, and left in a box with chloride of calcium, dried well in twenty-four to thirty-six hours, and this he thought a suitable plan for small batches.. Mr. J. Spiller said he used quick lime in the desiccator, this being much cheaper for the purpose, and quite as effective as chloride of calcium. The Chairman thanked those gentlemen who took part in the discussion, and then announced that, owing to the Gallery being unavailable on the usual evening in April, the next ordinary meeting would be held there on Tuesday, April 7th, and he hoped the members would bring examples of their work, either mounted or unmounted, to adorn the walls ; he should also be glad if as many as could make it convenient, would bring ex amples on the “New Rapid Printing Paper,” not forgetting to let them see some failures as well. The next technical meeting was announced for Tuesday, the 24th inst. South London Photographic Society. The ordinary meeting of this Society was held on Thursday, the 5th inst., at the House of the Society of Arts, John Street, Adelphi, W.C., Mr. W. Ackland, President, in the chair. The minutes of the February meeting were read and con firmed, and Mr. J. A. C. Branfield was elected a member of the Society. The Chairman announced that the subjects decided upon for artistic competition at the February meeting would remain in force until April, an arrangement which he thought would be agreeable, since there were very few competitors, and the lecture would occupy the whole of the evening. He then called upon Mr. Cecil V. Shadbolt to deliver his lecture entitled, “Adven tures in the Air; or, Balloons and Ballooning.” Mr. Shadbolt, in his opening remarks, told his audience that he did not intend to give them a highly scientific lecture, yet, while endeavouring to make it entertaining, he still proposed it should be as instructive as possible. The lecturer then dealt briefly with the history of ballooning, from the earliest notions regarding floating in the air, down to the present time. Many of the earlier notions were illustrated by means of lantern slides, and although the ideas were clever enough in conception, they were decidedly extravagant. The hydrogen soap-bubble experi ments of 1772, and those in which smoke was employed ten years later at Lyons, were alluded to, also the famous Mont golfier balloon, which in 1783 ascended to an altitude of 2,000 feet; after remaining aloft an hour and three-quarters, it de-
