24 THE PHOTOGRAPHIC NEWS. [January 10, 1868. about exposed cannot explode, even if you drop a coal of fire into it; if the liquid is confined, or is under pressure, then an explosion will ensue. If gunpowder or the fulminates of mer cury, silver, or gun-cotton be ignited in a vacuum by a galvanic battery, none of them will explode. PHOTOGRAPIY and the Kailway CARRIRRS.—A case of some interest to photographers in the transit of their productions has just occurred at Penzance. It appears when the Science and Art Department decided on allowing a series of their framed and glazed photographs to be sent to the West for exhibition, in connection with the schools of design at Pen zance, the agent of the railway into whose hands they were placed for transit to their destination entered the cases con taining the photographs, &c., as books. Now, to make the transaction better understood by the general reader, it should bo stated that the railway companies have three scales of charges : books, £2 per ton; pictures, with glass, £4 per ton ; and plate glass, £6 per ton. It appears that by a little sharp practice the person entered the pictures as “ books,” and got them conveyed at the rate of £2 per ton, and then charged those to whom they were directed for plate glass, at £6 per ton. Now the foreman of the Committee was sufficiently wise, though ho did not come from the East, to know that this was a very exorbitant charge, and refused to pay it, when another account was handed'to him somewhat lower; but this he deemed too much, went to the railway managers, had the whole affair opened up and inquired into. The case was then hoard before tho Penzance magistrates, who inflicted a penalty of twenty shillings on tho agent, at tho same time saying, that had the principals boon before thorn in the case they would have imposed the full penalty of £10 and costs ; so that photogra phers in sending their goods to exhibitions, &o., must be careful, and see that the cases are properly entered and properly described, as tho Act of Parliament gives the rail way companies great power in any case of wrong description and entry. Dishonesty.—Some weeks ago, we reported the committal of Walter Whitlow, for the theft of negatives, prints, &c., from his employer, Mr. Dufty, of Bath. At the recent sessions he was found guilty, and sentenced to six months’ imprisonment with hard labour. Photographs of Paintings.—One of the most colobrated landscape painters of Franco, who has just died, M. Theodore Rousseau, has, by his will, instructed that all tho works remain ing in his possession are to bo collected and photographed, and, if circumstances permit, they are to be published in a collected form, after the manner of the “ Livre de Verity ” of Claudo Lorraine, or of the “ Liber Studiorum ” of Turner. U0 Uorrespondeuts, A Subscriber.—There are various methods of making a plain paper print, transparent. Either wax or varnish will answer; but if you require it to be attached to glass the use of a varnish will answer your purpose best. The print should first be soaked in hot water to remove the size as completely as possible. It may then bo treated either with mastic varnish, or a varnish made by dissolving Canada balsam in turpentine. A strong spirit varnish might be used, but as it dries rapidly the manipu lation is not so easy. The print should be saturated with varnish, and the glass surface coated with varnish, and the two brought together carefully so as to exclude air-bubbles. F. A. N.—Tho best plan for such a side-light as y ours is to have tho curtains sliding on a rod with rings, the whole curtain for the side, triangular piece as well, being in one piece. A cord must run along tho rod, being attached to each ring, running over a pulley at the highest end, and hanging down. By pull ing this string the blind will slide along and up the rod; the cord by which it is pulled can then bo tied to a hook so as to hold tho blind in position, drawn just to such extent as may be required. 2. All the samples of albuminized paper you name are, we believe, good. We have, especially, heard Nos. 1, 2, and 5 praised ; but we have not made comparative trials of each, and cannot speak absolutely from personal knowledge. Amateur.—It is probable that the lens to which you refer, of tho maker you name, will answer your purpose ; No. 3 will be best for the size you require. For pure landscape, nothing will answer your purpose better than tho first landscape lens you mention. Possessing these two lenses you are right in con jecturing that the triple will be comparatively unnecessary. A Beginner,—The copyright of a photograph taken to order, and for what the statute terms a “ good and valuable consideration,” does not vest in either the producer, or the person ordering, without an agreement in writing made at the time, stating to whom the copyright is to belong. The producer of any photo graph ordered and paid for by another has no right to sell tho prints without the consent of the person so ordering ; but neither of them possesses a copyright without an agreement. The only case in which the copyright vests in the producer without any agreement is where he produces the photograph at his own charge and for his own purposes. The cost of registration is one shilling for the foe, and one penny for the “form” to bo filled up. Personal attendance at the Registrar’s Office is neces sary. Our Publisher will superintend tho proper entries, and pay the fee of a form properly filled up, if one shilling and three pence in stamps be sent to him. A separate entry and separato fee is necessary for every view of any object. Ono entry and one fee only protects tho picture in one negative, and any other negative with the slightest variation requires separate entry and fee. Twelfth Night.—The negative you forward is not well adapted to the production of transparencies for the magic lantern. It is not dense enough and not clean enough ; the lights are feeble and the shadows are fogged. For copying engravings for such a purpose you will find the use of an organico-iron developer well suited, as aiding in tho production of clean shadows. Your exposure has been a little too long also, and it is probable that your collodion is new. Try adding a few drops of tincture of iodine to your collodion until it is a deep sherry colour. In copying an engraving be very careful to have it quite flat and the camera quite parallel with it. 2. The use of a background painted in natural colours instead of in monochrome would not impede manipulations, but would make results uncertain and often inharmonious, because of tho varying photographic value of colour. 3. If judgment be used, natural objects may often be introduced as accessories in portraiture. We have seen, at times, very effective pictures produced by the introduction of natural foreground objects in front of a painted landscape back ground scene. G. Willis (Scarborough).—As Mr. Swan’s carbon process is protected by a patent, no one can, of course, work it without his licence. The possession of our work on carbon printing carries with it no right to practise the patent process, but will teach those possessing the licence to practise the process. The ques tion of exclusive licences is one of a purely commercial character, and will doubtless be governed by commercial consideration. W. M.—The Year-Book of Photography for 1868 was pub lished on the 27th of December, and has not been out of print since. Any answer” not out” or “ out of print” since that date has been given in error. Ajax.—We do not know of any agent for the Leptographic Paper in London. F. A. Oakes.—See answer above. R. N. D.—You require a thicker solution of india-rubber. The 15-grain solution with a large residue which you describe is prac tically much weaker, probably not more than 10 grains to tho ounce. 2. The thin foggy image which you describe may be duo to the condition of tho bath, or of the collodion, or of the deve loper. Probably you are using a new and somewhat thin collo dion. Add a little more pyroxyline to the collodion, and a few drops of tincture of iodine. 3. In copying a map, use a portrait lens or a triple to secure freedom from distortion, and a mode rately small stop. A view lens will curve the lines in tho margin. R. D.—The toning bath turning brown and ceasing to tone is most likely the result of contact with some trace of hyposulphite of soda. Possibly your fingers have been in contact with tho fixing bath, and have then been immersed in the toning solution. This will produce the effect you describe. There is no remedy for it; you can only recover the gold by precipitation. Tyro.— Collodio-chloride of silver properly prepared will keep in the dark a long time: how long we cannot say. The first sample we made was kept for twelve months before it became decom posed. We do not counsel, however, keeping it for more than a few weeks, as if free nitrate of silver be present, as it should be, it has a tendency to act upon the collodion, making the film rotten. The film leaving the paper is generally due to the use of a very tough collodion. Pickle.—Tho first of the recipes for joining glass to which you refer, if managed properly, will bo found to answer. A thick solution of isinglass with a little powdered hydrate of lime made into a paste will make a good cement; or, quicklimo and cheese made into a paste with a little water holds well. C. W. H.—Regarding tho subject of your strictures it is difficult to say anything here, except that there are many and varied tastes in existence. Thanks for your complimentary remarks on the Year-Book. To Correspondents.—Communications from Lachlan MACLACH- lan, A. E. Scales, and others in our next. Several Correspondents in our next.
