The Goddard Relief Fund.—Photographers are earnestly requested to respond early to the appeal made in our last, in favour of Mr. Goddard, the discoverer of the photographic use of bromine. Subscriptions already received will be acknowledged next week. Royal Portraits.—We have received from Messrs. South- well Brothers, some very pleasing portraits of various members of the Royal Family, recently taken at their studio. They con sist of the Prince and Princess of Wales, the Queen of Denmark, the Princess Dagmar, and the King of Greece, in various single portraits and groups, some of which are very fine indeed, not withstanding the unfavourable weather in which they were taken. Wo believe that the lens used was Ross’s No. 3 card lens. Tracing Linen for Blinds.—Mr. Cole has courteously for warded us some examples of the tracing linen to which he re ferred at the South London meeting as being valuable in shut ting out direct rays of the sun, without excessive diminution of light. One sample is labelled “ very old,” but is still perfectly white. Another article called “ tracing cloth,” is more opaque, and turns yellow with age. The tracing linen is thin and deli cate, and more transparent than tracing paper. It is to be had of various widths, 18, 28, 36, and 41 inches wide. Photography in Cape Town.—Mr Arthur Green, a cor respondent in Cape Town, sends us some very interesting card- portraits and remarks:—“ The best collodion that I can find is one I make myself; it is bromo-iodized, consisting of iodide of cadmium and ammonium, and bromide of cadmium, the latter in the proportion of one and a half to two of the combined iodides ; developer, double salt of iron and ammonia, 80 grains ; formic acid, 10 minims; water, 1 ounce; alcohol, quantum sufficit. Intensify with the formula you give, of 5 grains iron, 16 grains citric acid, water 1 ounce; and, if necessary, after fixation, with ordinary pyro and silver solution. Russell’s original tannin solution is found by the majority of operators here to be preferable to the tannin and honey, as being more certain : and although my experience has not been very great, still I can endorse this general opinion. Photographs at South Kensington.—It is stated that the sale of photographs of Raffaelle's Cartoons and other works, formerly conducted by the Science and Art Department, has been handed over to the usual trade publishers. Messrs. Chapman and Hall are the chief agents. The effect of this step has been very nearly to double the price. The Department in future will only issue to the Schools of Art in connexion with it. U0 Ooxxespondents. *.* Presentation Print.—With the Photographic News of January 1st, 1864, we shall present each of our subscribers with a beautiful specimen of Mr. Duncan Dallas’s process of photo-electric engraving. This process has been universally acknowledged to be the most perfect method of photographic engraving yet discovered, possessing perfect half-tone and gradation with great force and vigour. The subject is the “ Banqueting Hall, Kenilworth,” from a negative by Mr. Francis Bedford, the size of the print just permitting it to be used as a page of the Photographic News. The print will be from a plate untouched by the graver. It will be printed on toned plate paper, and will be valued as a charming picture, as well as an interesting illustration of a valuable process. To Agents.—As there is reason to anticipate a large demand of the No. for January 1st, agents are requested by the publisher to send their orders for extra copies as early as possible. Plato.—The silver in your hypo bath must be precipitated as a sulphide, by the addition of liver of sulphur. The silver in the washing water must be precipitated as a chloride by the addition of hydrochloric acid, or common salt. The gold in your old toning baths may be precipitated in the form of metallic gold, by the Addition of protosulphate of iron. You will find detailed instructions for these processes, and for reducing the metal, in our YEAR- Book, which will be ready in a few days. 2. So far as we can see, the irregular tint in the sky of your stereo print is simply due to a similar irregularity in the negative. 3. Formic acid is valuable in dull weather. The proportion can only be decided by experiment, as various samples differ so much in strength. George Stanham.—So far as we can see, there will be no difficulty in obtain ing a good position for a glass house at the top of your house. See papers and discussion at the South London Photographic Society, reported in the present number-; also, article on the subject in our forthcoming Almanac. 2. A strong iron developer is the best for winter. 3. Transparencies for the magic lantern may be taken by the wet process, but they require toning. See article on the subject, by Mr. Blanchard, in our Almanac. John Reynolds.—We believe Marion and Co. make albums for 10 by 8 pictures. Possibly also Solomon or Bourquin. Jonah.—You may take landscapes with a card lens, if you use a small stop. 2. All the collodions you name are very good ; perhaps a is the most sensi tive. 3. We are not familiar with the stocks of second dealers ; but we don’t think it probable, as a rule, that you would save much by purchasing second-hand dishes and pressure frames. R. G.—We do not know of any one at present, but will remember. J. S. W.—We strongly suspect that you have used carbonate of soda instead of nitrate, which would precipitate all your silver as you describe. See letters on this subject in the present number. Exposure of Tannin Plates.—A. A. sends us two prints from tannin nega tives which received from 20 to 25 minutes exposure on a bright day in September, with Ross single lens, 15 inches focus, -inch stop. Uis method of working resembles that of W. G. 0., described in our last, lie states that with a Fothergill plate he would obtain much quicker, although less certain, results. We cannot help thinking that by a modification of his method of working the tannin process, more rapid results might be obtained. See article in the present number by Mr. Hurst. G. Lewis.—The negative is very much under-exposed. Try a collodion containing double the proportion of bromide, or add at least a grain of bro mide of cadmium or ammonium to each ounce of the collodion you did use. Let your tannin solution not exceed 10 grains to the ounce, and give a longer exposure. There arc some interiors in which it appears quite im possible to get a good negative with a dry plate ; with a wet plate, it might be desirable to cover up the plain glass window opposite the camera with dark cloth for the portion of the time of exposure. Amateur.—The roof would be better in the form of the dotted lines, but the shorter half should be opaque. See articles in the present number. Eight feet will limit you somewhat in width ; six feet more each way would be an advantage. Chemicus has sent us a very pretty specimen of double toning. It consists of the portrait of a little child, the bright golden hair of which is kept very warm in tone, whilst the dress is of a warm or purple black. A Lady Amateur sends us an account of an old camera, much resembling that described by Mr. Kirkby, as Matthew Boulton’s. The date, 1843, was, of course, some years after the discovery of photography, but it is interesting to find a lady practising the art in a remote Scottish town like Moffat, so early as 1843. Java sends us a piece of the varnished yellow paper used in diaphanie, which he finds the best material for the dark room window, being easily fastened to the glass, or stretched on a wooden frame. It is of a deep, rich yellow tint, somewhat resembling the colour known as Etruscan yellow. We will report next week as to its non-actinic character. Negative.—It is difficult to form, from description, any certain idea of the value of such a room as you describe. A trial would be more valuable than an opinion, and the former you can easily make. Block up the window in the south end and place the background there. Then make a few trials with such light as you have, and send us examples of the results produced. We can then advise you as to the modification necessary. Your letter, which is dated Nov. 15th, only reached our hands this week. G. M. Redaway.—Thank you for the copy of rules, which maybe valuable in furtherance of the project. F. W. Evans.—Received, and will be acknowledged in due course. The other subject shall receive full attention in due course. R. M., A Subscriber «& initio. — Your letter has been forwarded to “A Photographer’s Assistant,” and you will doubtless receive a reply in due course. Some delay may arise from the letters being sent to him altogether and not singly, as received. A. B.—You will be able to get Turner’s negative paper of some of the dealers, but we are uncertain of who may have it in stock. We cannot tell you the wholesale price of transparencies. Nil Desperandum.—The prints have been fixed, or rather imperfectly fixed, in old hypo ; some traces of hyposulphite of silver have remained in the print, and subsequently become decomposed. Damp would facilitate such decomposition. Arthur Green.—The cards are very interesting, and the lighting very good. Several Correspondents in our next. Erratum.—In the letter on " Reduction of Residues by London Refiners,” in the News for December 4th an error occurs. The cost of 380 oun nitrate of silver at 3s. 5d. should have been stated as £64 18s. 4d., instead of £54 18s. 4d., showing that the offer of 380 ounces of nitrate of silver in return for 350 ouuces of chloride of silver was a very liberal one.
