208 THE PHOTOGRAPHIC NEWS. [March 27, 1885. cipitated, and he agreed with Mr. Debenham that it conferred a distinct feature in the quality of the plate. He believed the highest speed was obtained with a dilute solution boiled for some time. Regarding the sensitometer, be agreed with the Lecturer, that it was a most useful instrument when intelligently used. When shreds of emulsion were allowed to stick together round the sides of the vessel, twenty-four hours’ washing would not give a satisfactory emulsion. The whole paper was so interest ing and important, that he should move an adjournment of the discussion in order that they might have an opportunity of seeing the paper in print. He then called for a hearty vote of thanks to Mr. Henderson, which was accorded, and it was agreed to adjourn the discussion until April 16th. It was announced that on April 9th Mr. W. K. Burton would deliver a lecturette on “ Developers.” Hyde Amateur PHOTOGRAPHIC Society. This Society held its meeting on Wednesday evening, the 18th inst., a fair number of members being present. Mr. F. W. Cheetham occupied the chair. After transaction of routine business, the Chairman called on Mr. John Pennington to give a demonstration with the new printing paper. Mr. Pennington had several prints that had been previously toned and finished, and said these prints had been brought to show to what perfection he had attained with the paper. After exposing six prints to an ordinary gas flame four minutes, he at once proceeded to develop, tone, and fix them. During the demonstration, discussion was freely entered into as to the cost, time saved, and the results generally obtained ; many expressing themselves highly pleased with the paper. Bolton Photographic Society. The March meeting was held at the Baths, on the 5th inst., Mr. R. Harwood in the chair. The major part of the evening was occupied with discussing arrangements for the forthcoming soiree, to be held on April 22nd. Mr. Abatt gave a lantern exhibition, when Messrs. Knowles, Mercer, Austwick, and others exhibited slides. A number of coloured slides were also shown, prepared by Mr. Chatham Pex- ton. Ualh in the Studio. South London Photographic Society.—The next meeting of the above Society will be held at the Society of Arts, John Street, Adelphi, on Thursday next, April 2nd, at eight o’clock. Mr. G. M. Satchfield will give a demonstration of his “ Rapid Enamel Paper.” Messrs. Morgan and Kidd will exhibit the capa bilities of their “ New Paper for Negatives.” A New Departure in Printing.—In one of the series of articles on “ Gelatino-Chloride for Positive Printing,” written for us by Messrs. Ashman and Offord, there will be found work ing details for preparing a gelatinized contact printing paper that is sensitized on a silver bath by floating just like albumenized paper, and in all other respects treated in the same manner. It can be produced to give the highest or any degree of gloss, and appears to retain its whiteness in the sensitized condition for an indefinite period. The article in question, which will sh rtly appear, also deals with single transfer paper such as used by the carbon printer. This paper, when salted and sensitized, yields results of great excellence. Restoring Spotty or Stained Negatives.—This may often be satisfactorily done by converting the image into chloride, and redeveloping with oxalate developer. Belitski dissolves one ounce of alum in a pint of water, and then adds to this 140 grains of bichromate of potassium and three fluid drachms of strong sulphuric acid. The negative is allowed to remain in this solution until it has become thoroughly yellow, after which it must be very thoroughly washed indeed. It is now exposed to a bright light for some minutes, and then immersed in the oxalate of iron developer until it is quite black. Now rinse, soak in a solution containing one part of citric acid to fifty of water, and finally wash. The point most to be noted is a thorough washing after the bichromate bath. Colour-bred Curs.—According to the Sanitary Record, Dr. Horbacewiez has reared puppies in variously coloured lights, and he finds that the coloured lights, in their influence on develop ment, may be arranged in the following decreasing order:—Red, orange, green, white, blue, and violet. Dr. Horbacewiez also draws attention to a striking difference in the individual cha racter of puppies, according to the colour of light in which they lived and grew. Thus “ green ” puppies presented extreme live liness, cheerfulness, and playfulness, accompanied by ease and gracefulness of movements; in addition, they were invariably good-humoured and kind. “ Orange ” puppies were also prone to play, but their movements were heavy and awkward, and their temper rather cross—they fought each other on the least provo cation—and stubborn. “Violet’’and “blue” puppies were of a quiet, almost apathetic disposition, the “blue” especially so, since they never played. “ Violet ” showed a curious fondness for barking. “ Red ” puppies did not manifest any liveliness. Photographic Club.—The subject for discussion at the next meeting, on April 1st, will be “ On Toning and Finishing Prints on the New Rapid Paper.” The Hon. Secretary has removed from Hampstead to 1, Beacon Hill, Camden Road, N.

It is sold by Cornelissen, Artists’ Colourman, Great Queen Street, London, W.C. 2. About one-tenth of an inch may be taken as about the general thing, but less will be satis factory. 3. Quite practicable. The colouring is quite a matter of taste, and the fresh plaster does not adhere to the mould if this is well brushed over with an emulsion made by boiling together soft soap, tallow, and water. Make the preparation quite tbin. Let us know the result of your experience. P. Fincham.—Thank you very much ; we will endeavour to avail ourselves of your kind suggestion. Will you write a short account of it yourself, and make an illustrative diagram ? P. Moll.—1. Quite a matter of taste. Certainly it seems to us that the spot is by no means an ornament. 2. A meaningless phrase. Fred W. Cheetham.—Thanks for a copy of the presentation print; it is excellent. Forester.—1. You must be proposed by two members, and pay ft subscription of a guinea a year. The Photographic Society of Great Britain is the only one that publishes its proceedings in the way you mention. It will give us much pleasure to propose you as a member. 2. The maker does not intend the lens to be used in such a way, but good results are generally obtained. Try it with the back lens partly unscrewed, so as to give greater dis tance. If any, it would be complex, and would require a know ledge of each one of the four curves, and the optical qualities of the two kinds of glass used, so perhaps it would be better to find it by experiment. 3. Not yet. William Lang, Jun.—I. They shall be sent you, if they can bo found. The small dynamo referred to weighs about 180 pounds, but more portable and equally useful instruments are now made. We will write to you. L. W. Kessler.—It is not made commercially, as workers gener ally prefer to prepare it themselves. Dee.—Nothing of the kind. The Act only applies to the retail business, and not to wholesale transactions or sales to trade con sumers or manufacturers. R.
