January 9, 1891.] THE PHOTOGRAPHIC NEWS. 35 the camera to be readily moved from place to place, all the lids are closed, and the before-mentioned stops are disconnected and swung about their flexible hinges and laid flat against the front plate. The bellows is then compressed and attached to the rear of the door which is at the back of the camera by means of an india-rubber band, the whole being thus made to assume a compact form. The rubber band passed over the front sheet or plate across the stops and across the door or lid at the front of the camera, also serves to secure the latter in position, and the whole camera being by such means reduced to a portable size, may be easily carried about in the pocket or otherwise. 16,037. October 9th, 1890.—« Printing on Glass and Porcelain.” Hermann Gravel, Paulstr., Berlin, Merchant. This invention has for object the rapid and easy printing chiefly of label-like and ornamental designs on objects of glass, porcelain, and like materials in one or more colours. This is accomplished by means of an apparatus in which, by the turning of a lever or frame, colour is carried by rollers from a pad to a rigid printing plate, from which the matter to be printed or impressed is transferred to an elastic plate in readi ness for the printing operation. The inventor claims :— 1. The process for printing on flat or curved surfaces of glass, porcelain, and like materials, label-like and ornamental matter in one or more colours, consisting in so operating back wards and forwards a lever or frame carrying a plate of elastic material, that this latter is alternately moved against a print ing plate containing the design, and turned over with its elastic and impressed surface ready for printing from, or consisting in so operating backwards and forwards a lever or frame, carry ing a rigid printing plate, that this latter is moved against a plate of elastic material, and away from the same, leaving the elastic plate impressed, and ready for printing from. 2. In carrying out the process referred to in the preceding claim, an arrangement for obtaining the negative picture on an elastic plate, comprising a lever or frame carrying the elastic plate, operated backwards and forwards, the elastic plate being brought in contact with a printing plate containing the matter to be printed, and a colouring roller or rollers in connection with the lever or frame, and operated by it, so as to supply colour to the printing plate after the taking of each impression therefrom. The Deutsche Photographen Zeitung opens its New Year greeting to its readers with the announcement that the number of copies printed will be raised to three thousand. Liverpool Amateur Photographic Association.—Applica tions for space in the International Photographic Exhibition must be made before the 20th inst. Full particulars will be sent on application to Mr. T. S. Mayne, Fenwick Court, Liver pool. Boxes for Lantern Slides.—At a recent meeting of the New York Society of Amateur Photographers Mr. Beach said :— "Iwould like to call your attention to a new method ofpaeking lantern slides which I have just devised. It is a method which has for its object the safe transit of slides when shipped by express. Heretofore the trouble has been that the thin wooden grooves of the boxes would sometimes crack off and break, and the slides in transit would consequently push against each other or strike each other and become cracked. Now, to avoid that, it occurred to me to make these divisions of very thin rubber, and by doing so we are able to get a thinner division, and are able to get a great many more slides in a given amount of space, and I estimate that you can pack fifty slides in eleven inches of space, whereas, ordinarily, it takes about fifteen or eighteen inches. The way this is made is simply by taking two boards that are grooved with a saw, and then these strips of rubber—rubber belting—are glued in. Another and a better way is to have a mould made and cast the rubber the same as you would a rubber mat, and I will say that I am about to have these made ; when that is done all you have to do is to tack them or glue them' on to the side of the box ; then you will have it all complete, and you can throw this package around wherever you want to, and it will not break. ” Correspondence. ZOOLOGICAL PHOTOGRAPHS. Sir,—I have just read your article, page 218 in the Year- Book, and am rather surprised to learn that the list of animals I photographed nearly twenty-seven years ago contained so many, as you put it, “generally more unsuccessful.” The photographs of many of the animals mentioned by you as failures were shown by me in the lantern at a recent meeting of the Photographic Club, and I do not think they were con sidered failures by those present. You do not seem to be aware that the clouded tiger is an animal easily tamed and often kept as a pet in the East; there my reason for not entering his cage was the true one. Con sidering that I did go into the enclosures or cages of many of the animals, the insinuation is uncalled for. That better work than mine ought to be done now with all the improvements in cameras, lenses, plates, and chemistry, is only natural, but I believe I may claim to have been the pioneer. I shall be much obliged by your inserting this in the Photographic News, and I think it ought also to appear in your next Almanac. Frank Haes. 28, Bassett Road, London, January 5th, 1891. THE FIRE IN HOLBORN. Sir,—With reference to the disastrous fire, on the evening of 5th inst., at Messrs. Stone and Co’s, warehouse, adjoining our factory, 9, 10, 11, Fulwood’s Rents, would you kindly allow us tostate in your columns, in consequenceof thenumerous enquiries we are receiving, that our premises have sustained but slight damage, and not sufficient to inconvenience us materially in the conduct of our business. W. Watson and Sons. 313, High Holborn, London, W.C., January 6th. Proceedngs of Socettes. The London and Provincial Photographic Association. January 1st.—Mr. A. Cowan in the chair. This was the first meeting held at the new quarters, the Champion Hotel, 15, Aldersgate Street, London. The Hon. Secretary announced that Dr. P. H. Emerson had presented his new work, “ Wild Life on a Tidal Water,” to the Association. Referring to the subject down for discussion—viz., “De velopers ”—Mr. F. P. Cembrano said his standard developer was Pyro 2 grains Ammonia ... ... ... ... 2 , Bromide ... ... ... ... 1 grain to each ounce of water. For instantaneous work, he preferred carb, soda to liq. ammonia. A useful formula he had found to be three parts of eikonogen and one part of hydrokinone used with carbonate of potash. Mr. A. Mackie, for studio work, would use much less pyro and bromide. Mr. W. E. Debenham had some years ago used a very good studio developer, the formula for which was— Pyro ... ... ... ... ... 1 grain Ammonia ... ... ... ... ... 3 grains Bromide ... ... ... ... ... 1 grain to each ounce of water. This was also a good landscape developer for suitable plates correctly exposed. On the question which was the best solution to keep the bromide mixed with, he preferred to keep the three solutions separate. Mr. A. Mackie, for indoor work, mixed the bromide with the ammonia, but for landscape work lie preferred separate solutions. Mr. J. S. TEAPE, in cases of great contrast, used no bromide at all, and started development with the full amount of ammonia. Soaking the plate in plain water decreased the contrast.
