Drak Siz,—An article in your November issue is entitled ‘Can dissolving effects be produced with a single lantern?” and this question brings to my remembrance , the fact that some of the most beautiful dissolving i effects I ever saw were produced by a single lantern. It ; Was many years ago since I first saw the instrument ‘shown in Cardiff, and the way in which the change was : effected could in no wise be detected from a pair of . instruments. I did not at the time trouble to investigate ; the matter, making sure, as so many silly people do, that such an invention would be certain to be somewhere on ; the market. But it slipped my memory. ’ Three years ago, a travelling lanternist asked the use of my Parish Rooms for an exhibition of dissolving views. I lent him a few of my own slides, and took the chair in the evening. At the close I said to him, “ How beautifully your lanterns work; the dissolving is simply perfect.”’ ‘No, sir,"’ he replied, “ its only one lantern.” I could scarcely believe his statement ti!l after investigation, ; and the man informed me that the lantern had been a patent, but owing to the enormous cost, about £50, it had years before been forgotten. It was too late to thoroughly examine the lantern then, but I remember that there was one limelight burner, one condenser, two objectives, and the dissolving was done by a very perfect and beautiful flint glass prism of four inches width. By simply turning the prism, the picture from the condenser was thrown upon the front lenses alternately, and the excellent results I have described were produced. I was further ' informed that the lantern I saw was supposed to be the only one of its kind now existing. The owner refused my offer of £20 for it, stating that he could get that for the prism alone. Perhaps some of your readers may know something of the principle involved, or of the particular invention itself. Yours, etc., J.J.S, BIRD, B.A. FRESH LANTERN SLIDE WORK. To the Editor. Dear Srr,—After reading Mr. Tranter’s article on care to add to his list a few interesting subjects which we quaint old churchyard (in the valley under Holwood Mulock, or, as she was locally known, Mrs. Craik, She often used to drive over from her home at Shortlanda in her little pony chaise over the beautiful common of Hayes and Keston, and round the little old churchyard. She had a great wish to be buried here, in a quiet little corner under old elms. Then we have in Holwood Park, just above, within sight of her grave, the fine old oak known as the Wilberforce or Emancipation Oak, upon the roots of which Pitt and Wilberforce first thought of bringing in the bill for the abolition of the slave trade, under which a stone seat bears the following inscription from Wilberforce’s diary, 1788:—‘* At length, I well remember, after a conversation with Mr. Pitt in the open air, at the root of an old tree at Holwood, just above the steep descent into the vale of Keston, I resolved to give
