240 THE PHOTOGRAPHIC NEWS. [May 16,186- Ualh in the Studio. PHOTOGRAPEY in the Exhibition.—We observe with plea sure that, notwithstanding the inferior position accorded to photography by Her Majesty’s Commissioners, the “leading journal” regards it as worthy of repeated and prominent notice in its criticisms on the contents. Of the British department it recently remarks:—“ We mentioned yesterday, with the praise they deserved, the very fine collection of French photographs in the south gallery, though we now learn that some of the very best in this display are by English artists resident in France. Some remarkably good ones are sent by Mr. Maxwell Lyte, an amateur, whose pictures may be at once known by the words, ‘Lux fecit’—a true photographer’s pun on his name and art. Mr. Bingham, too, one of the best of the Paris professionals, sends some fine specimens, which go far to keep up the general excellence of the French show. There is a special class devoted to English photography in the building, which contains some of the finest specimens of the photographic art ever brought together. There was no class devoted to photography in 1851, and there was near being no exhibition of the art on this occa sion, in consequence of the most unfavourable place assigned to it. As it is, the London Photographic Society have refused to exhibit, and, but for the efforts made by the most eminent photographers, the art, as regards England, would have been unrepresented altogether. The photographic collection is placed along with the class devoted to educational appliances, in a large room in the upper floor of the tower, between the English and foreign picture galleries—about the most inaccessible and unfavourable spot to which it could be banished, but to which we feel now justified in calling the attention of visitors, as con taining a collection which will repay a long visit. Here are collected the finest portraits of Williams, Claudet, Watkins, and Mayall, Caldezi’s copies of miniatures and cartoons, the exquisite views of Bedford, Fenton, Cundall, Downes, and White, and the fancy pieces of Robinson. Frith also sends specimens of three great views in the East, which were taken for Negretti and Zambia. Some of the best exhibitors in this class are to be found among the amateurs, of whom there are many, such as Colonel Sir Henry James, the Earl of Caith ness, Lady Jocelyn, Colonel Verschoyle, Colonel Stuart Wort- ley, Sir A. Macdonald, &c. The educational appliances in this department of the Exhibition likewise deserve an attentive visit.” The error made as to the Photographic Society having refused to exhibit, will be understood by photographers as a misconception as to the nature of the steps taken some months ago.” The PHOTOGRAPHIC Contract at the Exhibition.—We intimated a conviction a few weeks ago, that the impossible conditions attached to the photographic tender, for the privi lege of photographing in the Exhibition Building, had a definite purpose, and was part of a little scheme of jobbery. An adver tisement which appears in the official catalogue, affords a striking illustration of this idea. A certain firm who have not obtained the contract, had made such arrangements and received such assurances, it would appear, that the contract was already regarded as secured. Accordingly, in the advertisement in question, the firm to whom we allude, announces the publica tion of a series of views of the interior and contents, taken by Mr. Francis Bedford! Rumour tells other curious tales on this subject, which we forbear, however, to chronicle. We may mention one incident we have heard related, however, which throws some light on the source of the scurvy treatment photo graphy, generally, has recieved in thisinternational undertaking. Afewdays ago Mr. England wasengagedinphotographingapiece of machinery in the annexe, and had placed an attendant in such a position, as to show relative size, &c., when one of the commis sioners passing, immediately denounced this as a breach of contract, styling the operation as taking “ shilling portraits,” and obtaining a sight of Mr. England’s pass or warrant unhesita tingly appropriated andput it in hispocket! A telegraphic message brought Mr. Nottage, who took prompt measures to have the pass restored, and his staff put on a proper position, safe from further indignities. Without mentioning this commissioner’s name, we may state that it was the same gentleman, who, some time ago in certain evidence before the House of Commons, denounced “photographic professors” as “pests!” Wethen said photographers were obliged by his good opinion. They may now guess how much more they have to thank him for. Uo Corxespondents loper, ana Derore nxing. W nen a slight amount only of additiona Id is required to give decision to a picture full of detail, the samera may be applied after fixing. Dr. Diamond obtains a good effect by a thin negative for a few hours in a bath of old hypo, until the in, sulphuretted. One of the best methods we know of obtaining intenst, retaining delicacy, is that effected by means of bichloride of mercua iodide of potassium ; but requires careful management. Whenne mastered, it is a very efficient method. Avoid overloading the neg a with intensity, or you will certainly bury detail. It is better as a 5" rule to varnish negatives. .g M.

We presume you probably meala; lenses of the same focal length. This will depend entirely on thecoth tion and diameter of the lenses. In regard to the lens of which you6c it will work more rapidly and perfectly with the same aperture thanl mon lenses of the same focus. J. II.

But we fear the defect of size, and too little glass is a radical one, and can only be palliate cured.

For prices, see advertise We shall be glad to hear from you. W.—We are glad you have found the method described practically^ and are obliged by your good opinion. We have no intention of n0do such matters as those to which you refer. They are too small for attee and our space is demanded for more important matter. We don'tCg deal in counter-imputations, however easy to establish. It is unnec to disprove what nobody regards or believes. You will see the proP therefore, of not inserting your letter.

Bear in mind that oil colours dry veryoss, especially in damp cold weather: the pictures should be kept, if in a room at a temperature of about 60° whilst painting.
