JANUARY 9, 1885.J THE PHOTOGRAPHIC NEWS. 25 seen, his specimens showing a complete scale of tints from red to a purplish black. The formula of Mr. Wellington will be found on page 31 in the report of the London and Provincial Association, and in giving it, the author assumed his hearers to have a general knowledge of the manipulations incidental to making and washing an emulsion. Those readers who may wish to try Mr. Wellington’s formula will find informa tion as to making an emulsion on page 595 of our last volume, formula for Edwards’ oxalate developer on p. 157 of the same, and some account as to the best method of coating paper, on page 2 of our present volume. The clever Italian to whose artistic doings on the Stock Exchange, the Corn Exchange, and other well-known City centres, we drew attention in a recent issue, has brought his enterprise to a conclusion with a completeness which does credit to his business faculties. His collection of the caricature portraits of the city celebrities, after being on view for some time, was brought to the hammer a week or two ago, and realised good prices. A smart stroke was the publication of a half-a-crown catalogue, illustrated with thumb-nail reproductions in photo-zinegraphy of all the pictures. The production of this catalogue constituted an admission ticket to the auction room, and only those so provided were allowed to enter. As the room—by no means a small one—was crowded, the profit from the sale of catalogues alone must have been considerable. Although many of the persons whose peculiarities were faithfully reproduced by the artist were very wrath at being carica tured, others were pleased rather than the reverse, and many commissions for portraits on a more substantial scale have resulted. On the whole, the artist has made a good thing by his speculation. grapher who has a large clientele among that body, reveals a fact worthy the attention of Mr. Francis Galton. This fact is the strong likeness which exists between nearly every one. Each has that peculiar gleam in the eye which denotes the enthusiast; the shape of the faces, especially those of the females, has a wonderful similarity ; while everybody has a sort of pattern smile hovering about the mouth, of which most probably the sitter is unconscious. It is quite possible, could the subject be fully enquired into, that photography would conclusively prove that the tactics adopted by the Salvation Army affect only those whose mental powers are unequally proportioned to their emotional tendencies. If this be so, some light might be thrown on the problem, that exercises the minds of so many orthodox religious men, how, to use the phrase of the day, “ to reach the masses,”—a problem which the Salvationists hold they have solved. Aatent ntelligence. Patent Granted in America. 309,736. John H. Parsons, Wheeling, W. Va. “Photographic printing-frame.” Filed June 19, 1884.—(No model.) Claim.—1. The combination, with a photographic printing faame, of side clamps having oblique slots, and secured thereto by means of set-screws, and provided with down-turned flanges at their upper edges adapted to hold a longitudinally movable vignetting-plate. 2. The combination, with the longitudinal clamping-plates, of the vignetting-plate with flanged sides adapted to move longi tudinally under the clamping plates. 3. The combination, with the vignetting frame having an inclined rim, of the similarly shaped hood hinged to the vignet ting frame, whereby the angle of said frame may be adjusted. 4. The combination with the vignetting frame of springs ex tending from the centre to each end of the frame, and cross wires whereby the vignetting plate may be adjusted and held. With the new year Anthony's Photographic Bulletin will appear fortnightly, and, as we have already stated, Prof. C. F. Chandler, of Columbia College, will take the edi torial chair lately occupied by Mr. H. T. Anthony. Dr. Arthur B. Elliott will be sub-editor. At Harvard college, photography is used to take registers of every change in the electrical condition of the atmo sphere, and it is said that the records obtained wil be of material service in making reliable weather forecasts. The relative advantages of collotype and wood-engraving have been compared by Herr Gaillard, who has recently issued anillustrated edition of “ Goethe's italienische Heise." “The wood-blocks cost much, but the printing is cheap . while the collotype plates involve very little expense in making, hut printing from them is an expensive process,” s »ys Herr Gaillard. Hence collotype steps in very advan tageously for small editions. A scrutiny of a large collection of the photographs of members of the Salvation Army, possessed by a photo- ENLARGING ON GELATINO-ARGENTIC BROMIDE PAPER. BY F. C. BEACH.* It has been claimed by some that very complete and perfect apparatus is necessary; to be sure, it is advisable. I know, how ever, of one instance where a very successful enlargement was made with the roughest tools, such as a common soap box to hold the lamp, shielded at the top with a long length of an old stove pipe, a piece of ground glass placed in front of a negative, and a Harrison C lens, such as I have here. The enlargement was made nearly life-size, with an exposure of twenty minutes. The development was carried on in a common wash-tub, and the print, after being fixed, was washed over night by soaking in the bath-tub. It will thus be seen that in trying the experiment of enlarging, the amateur need not go to much expense for apparatus, provided he has a good negative, a good lens, and well-coated paper to work with. The most suitable lenses for enlarging are what are known as portrait or short focus lenses, or any good objectives such as arc used for lantern work. View lenses can be used to good effect, but with them a longer exposure is generally required. The light (said to be equal to from 28 to 30-candle power) emitted from a Moehring-Harvard kerosene round-wick burner, obtainable at any large lamp store, I regard as excellent, as it gives a whiter flame than many other kinds of burners, which, experience shows, is desirable in order to obtain the best effects. I speak of this light specially, as I learn that it has been carefully tried when used in making enlargements without the aid of a condenser. • Head before the Now York Society of Amateur Photographers, at their meeting of December 9tb, 1884.
