166 THE PHOTOGRAPHIC NEWS. [April 4, 1862. Correspondence. by W. Class A.—Nos. ■ * Now Licut.-Col. Shakspeare, we believe.—Ed. selected to com- the contrary the exception. In most cases persons had the power of accomodating their eyes to the stereoscope notwith standing. Where the difference between the force of tho two eyes was so great as not to permit this, a stereoscope with adjusting eye-pieces should be used. Mr. Shadbolt said that the remark of Professor Macdonald would have had force as an explanation, if the persons who failed to see the stereoscopicity of these pictures failed in the same way with stereoscopic pictures generally; but where the failure only referred to these pictures, and not to others, the want must be in the pictures and not in tho individual. The Chairman announced that the Council had been taking into consideration means of giving increased interest to the meetings of the Society. As one method, it was suggested that members generally be invited to bring, from time to time, specimens of any interesting photographs they might have pro duced, or had access to. It was proposed to provide stereo scopes by which slides might be examined if brought as he suggested. He trusted members generally would feel that they could all in some way contribute to the interest of the meetings, and that by so doing all would be gainers. It was then announced that the subject for tho next meeting would bo a paper “ On Enlarging Photographs ” by Mr. Vernon Heath. It was also announced that the Soiree of tho Society would be held in the large hall of King’s College on tho 25th inst. awarded discussed, a certain number of the pictures, by the various members of tho Committee as entitled petition, wore laid upon tho table.

Besides that by Major Gresley, on which a prize has already been conferred, the one numbered % is, perhaps, if possible, even more artistic in selection of subject, but not quite so per fect in execution. % and 1 are also particularly worthy of commendation ; and indeed tho whole of this gentleman’s con tributions display the work of a true artist. Mr. A. C. Ainslie’s, No. ‘9, is very artistically rendered, exhibiting a field-gate in the shade of a handsome tree ; and scarcely less so are The Gate of Corfe Church, Somerset, 320 ; The Grove at Barton Grange 19°; and The Waterwheel al Corfe, 190: Mr. W. Prideaux’s Fishing House, 170, is a photographic gem. Mr. E. Edward’s Cleft in the Rock, near Aucher Church, Derby, 12, elicited much admiration; as also his doisters at Netley Abbey, ?2, and many of his views in the Isle of Wight. Captain Plaiffin’s Arab Girl Sitting by the Wayside, 8, is a highly interesting figure subject, admirably treated; and " landscapes, 144 and 1 #, are deserving of especial notice. Mr. C. It.

J In conclusion, the Committee congratulates tho membe” upon tho discovery and utilization of so many valuable negative of which but an insignificant fraction is indicated in the abon list. PAINTING SLIDES FOR THE MAGIC LANTERS Sir—In answer to your correspondent who inquires abot tho preparation of the colours used in painting mag, lantern slides, I give the following information. He ‘ quite right in supposing the vehicle to be Canada balsa The colours used aro gamboge, asphaltum, burnt sien crimson lake, (in drops) and Chinese blue ; and sometin. vegetable black for vigorous touches. The various ti” are got by a mixture of the above. The mode of prepa” tion is as follows: first take gamboge one ounce and b into small pieces, put them into a bottle containing 1 i ounces of alcohol and set in a warm place to dissolve 2 colouring matter or the gamboge : this will take about days. It must be well shaken from time to time to a the solution. The supernatant liquor to be poured off sediment on to a warm slab of glass or marble ; the war" being necessary to assist the evaporation of the alcol® The colour should be kept in the centre of the slab witll palette knife: it will soon appear thick and opaque. 2 little Canada balsam must now be added and well work’ in, and as soon as the alcohol is all out, the colour will rest its former transparency, and have a thicker consistency 31 a little be tried on a glass it will show the color to be a" yellow. .. J Next prepare the asphaltum: it is to be dissolved 1 turpentine and allowed to settle. A little of the liquor 1 be poured off and mixed at once with the balsam. The ot, colours, crimson lake, burnt sienna, and Chinese blue, J to be ground on the slab in the order written ; as theb is very bad to clean off, it must be done last. The Co0 are to be reduced to a fine powder on the slab, and a h turpentine added with which the colour must be ground fine as possible. It may be ascertained how they arc 80155 on by taking a little on a brush with some balsam 4 turpentine, and drying it on a piece of glass. It wila an hour, at least, to grind a piece about the size of a Dv unless you have a large slab and muller, which mus of of either ground-glass or marble. The quantity used, ( ever, in each picture is so small that little colour will c | a large number of pictures. fredl In painting, it is usual to lay on the sky pretty In with a soft sable brush, a black one is best, and as S00s6v ready, in order to remove the marks of the brush, it mu I A? dabbe kid gl to giv views.
