very materially. He then intimated the results of a competi tion for landscape prints, in which sixteen sets had been forwarded. In the size 5 by 4 five sets had been given in, and the prizes had been awarded as follows :—1, Mr. D. Ireland ; 2, Mr. D. Ireland; 3, Mr. J. R. Stewart. For half-plate and larger pictures there had been eleven competitors, and the result was as follows :—1, Mr. V. C. Baird ; 2, Mr. V. C. Baird; 3, Mr. D. L. Honeyman. Mr. Andrew SrEWART then read a paper on “How our Members make their Lantern Slides,” and, in the course of an interesting address, remarked that the tendency of the times seems all towards small cameras, and it would appear as if the hand-camera was to be the instrument of the future, for all the mechanical skill of the instrument-maker is now bent in the direction of perfecting the detective camera. Mr. J. W. Munro exhibited a very ingenious hand-camera he had designed and made himself, of magazine pattern, and carrying three dozen quarter-plates ; in point of size less than most magazine cameras carrying only one dozen plates, and having the advantages of being able to focus at will, and use lenses of different focal length, without in any way altering the general mechanism. Richmond Camera Club.—On Friday, the 2nd inst., was held the first lantern night of the season, when slides by Messrs. Ardaseer, Cembrano, Davis, Arthur Hunter, and Lowry were shown. Photographic Club.—October 14th, first lantern night of the season: October 21st, “The Theory of Development”; October 28th, smoking concert and exhibition of members’ pictures. Silver Chloride.—-A layer of silver chloride, after exposure to light, consists, according to Mr. Guntz, of three superimposed layers—metallic silver, sub-chloride of silver, and unaltered chloride of silver. By “ sub-chloride of silver ” is meant the violet-red substance produced when the chloride is left exposed to the action of light for a considerable time—say for three or four hours. It is not yet quite certain whether this substance has the composition of a sub-chloride, or whether it is a mix ture of chloride and of finely divided metallic silver.—Monthly Magazine. The Czar and the Photographer.—The following is quoted in a daily journal from the World, a recently founded Berlin newspaper :— The Czar does not like having his photograph taken, especially when he has to stand alone in front of the camera or is subjected to the process unexpectedly or suddenly. A Danish photo grapher found this out two weeks ago. He had taken up his position on the road which leads from the castle to the station, near the Fernbane Hotel, in order, when the Czar took his usual morning walk to the station, to catch him, and to force him, in a sense, to give him a sitting. The Czar came, as luck would have it, quite alone, when suddenly to his left he heard the ominous elick-click of the instrument. He immediately turned sharply round, as if the shadow of a danger had crossed his path, and saw ten paces off the black camera, which, being dazzled by the sun, he evidently did not at once recognise. “ I stood here at the window,” continued my informant, an old female servant of the royal family, “ as I was living here, there being at the time no room in the castle, and I saw the whole scene. The Czar’s face was whiter than my apron ; the stick, which shortly before he had been care lessly waving in the air, fell from his grasp, and he trembled like a frightened fawn in face of a sudden fright. But then, as if by a sudden determination of will, he collected himself, and, as the photographer came forth from behind his box with a humble request, he gave him a look which made the young man tremble, and the words died on his lips. ‘ Jamais !' hissed the Czar between his teeth, picked up his stick, and hurried back to the castle, a group of children running to meet him. In their midst he most likely soon regained his composure. The photographer,” the old woman concluded, “returned by the next train to Copenhagen. He was very near fainting, the poor fellow, and for half-an-hour nearly lost the power of speech, such an impression had the Czar’s enraged looks and his imperious ‘ Jamais !’ made upon him.” Answers to Correspondents. AU Advertisements and communications relating to money matters, or to the sale of the paper, should be addressed to the Publishers of the PaotogRaPNIO News, Messrs. Piper & Carter, 5, Furnival Street, London. All Oommunioations, except advertisements, intended for publication, should be addressed to the Editor of the Paorograparo News, 5, Furnival Street, London, E.C. Questions requiring a reply in this column should be addressed to Mr. John Spiller, F.C S., 2, St. Mary’s Road, Canonbury, N. R. Me. D.—Convergent Perpendiculars. You may have raised the rising front even to the full extent of the adjustment, but the fact remains that the lens was not raised enough in this particular instance to bring in the whole of the tower without tilting the camera, and yet the foreground shows that there was room for more elevation. Can you not draw out the screws on occasion, and get the sliding front to cover the aperture whilst you are at work ? This can often be done without letting light into the camera, and in this way you would secure true perpendiculars and correct perspective. E, B.—Reducing Hard Negatives. A good formula for a chromic reducer was published a fortnight ago in the News (page 670). The cupric bromide solution mentioned last week may contain 5 grains each of sulphate of copper crystals and bromide of potassium, with 20 to 30 grains of common salt dissolved in the ounce of water, but for the treatment of very dense negatives the proportions of copper salt and bromide may be doubled. J. E. D.—Novelty of Invention. Yours is just one of those doubtful cases giving scope for difference of opinion regard ing its novelty. The principle is not altogether new, but the method of carrying it out seems to be sufficiently re moved from previously recorded plans to justify a patent being granted. You must not, however, rely upon the un supported opinion of any one adviser ; it might even be worth while showing the model and drawings to Mr. Moulton, Q.C., or Mr. Graham. A. T. (Walton).—Magnesium Chloride for Fixing. If you look again at the table of solubilicies you will find that chloride of calcium is stated to be equally efficient, and, being much cheaper, should first be tried as a solvent for chloride of silver. We shall be glad to hear the result of your ex periments. H. A. W.—The New Iron Salt. We have, of course, seen the letter to which you refer. It rests now with Mr. Greene to clear up the matter. M. P.—Single Fluid Developer. A correspondent has kindly given us the formula of a single fluid developer, which is said to keep well in closely-stoppered bottles. It was described by Mr. A. Cowan at one of the meetings of the Photographic Club, and made as follows :— Eikonogen 8 grains Sulphite of soda ... ... ... 64 „ Carbonate of lithia ... ... ... 4 ,, Water ... ... ... ... ... 1 ounce Half the above strength is suitable for developing bromide paper prints. Here the lithia salt plays the part of an exceedingly mild alkali, and it might be well worth trying whether borax will not answer the same purpose. A. J. S.—The Year-Book. Your promised help in the shape of a contribution will, no doubt, be very acceptable to the Editor, who desires to gather in his matter at as early a date as possible. M. W.-—A Chemists' Benevolent Fund has been started on the lines of our Photographers’ Benevolent Association, and is intended to be applied in relieving necessitous cases within the chemical profession. More than £1,600 has been already promised or subscribed, many donations amounting to £50 and upwards, besides a long list of annual guineas. Polytechnic Technical Schools (Photographic Department). —The tenth winter session of instruction in photography will commence on Tuesday, October 20th, at 8 p.m., when Mr. W. E. Debenham will give the introductory lecture, which will be explanatory of the general principles of photography, and, in addition, will include a paper on “Perspective in Relation to Photography,”
