All information can be obtained from the hon. secretary, Mr. Gilbert Wood, 10, Pelham Road, Southsea. ae te Cinematograph Films—a Reduction in Price.—On the 3rd of last month, the Warwick Trading Company, Limited, made a considerable reduction in the prices of certain of their films. According to subject, the prices now vary from 30s. to 50s. per 50 feet. The difference in prices between the various classes is gauged according to the initial cost of procuring the negative. Thus a negative in London may cost a few pounds, whereas if taken in a distant oe country the cost may be reckoned by hundreds | of pounds. x * a The Late Mr. Leon Warnerke. There are ; many who will hear with great regret that the death of Mr. Leon Warnerke has left his wife and daughter in very straitened circumstances, and in urgent need of immediate assistance. Mr. Warnerke’s work in photography was so well and widely known, that a large number of those who were friends of his, or who appreciated his good services to photograpby and his kindly help to all photographers, will, it is felt, be ready to take part in a subscription raised on behalf of his widow and daughter. A committee, comprising Sir W. de W. Abney, Sir Henry Trueman Wood, Mr. J. Cadett, Mr. L. R. Dallmeyer, Mr. G. Davison, Mr. F. Ince, and Mr. H. W. Teed, has been formed to assist in raising and administering a fund to assist Mrs. and Miss Warnerke. Contributions are earnestly requested. The Editor will be pleased to receive subscriptions on behalf of the fund, or they may be sent to the Treasurer, Mr. Francis Ince, 15, Netherhall Gardens, Hampstead, N.W. ~~ m ~~ Exhibition of Natural Colour Photograms.—An exhibition of excellent photograms in natural colour was held at the Queen’s Hall, Langham Place, W., on the 18th ult., when a great number of pictures in the form of lantern slides—supplied by the Colour Photo Company, of Birkbeck Chambers—were projected on the scrcen. Mr. H. Snowden Ward gave a brief outline of the McDonough process, in which the picture was taken through a plate of glass ruled with fine parallel lines of alternately red, green, and violet; and further explained many of the. pictures as they were projected on the screen. A series of interesting Pictures in colour, taken at Oberammergau by Mr. C. N. Crewdson, were explained by the artist. ans = ; {_N@ 21. PUNCHSJuDY. YaNe J x the construction of the present id slide—“ Punch and Judy Dining ”’ —the final object has been not to achieve something very involved and complicated, but to give a faithful representation of a simple action, that of eating. When he has constructed it, the reader will, on exhibiting it, be surprised at the very natural effect obtained on the screen, and this effect ig greatly added to by a judicious manipulation of the working part. The following particulars will enable any reader to make this simple, yet effective, shadowgram slide, The framework 1 (see diagram), which is of the same dimensions as the ordinary framework slide, is made of wood. Two glasses, one fixed and the other used solely as a cover-glass, are employed. The black portion of the diagram must be cut out of thin wood and glued to the fixed glass as shown. It may be remarked here that the dotted lines round the eye and chin indicate the outline of the two figures before the parts a, B, etc., are attached. When this portion has been firmly glued to the fixed glass, we have a suitable base on which the other working parts, all of which (except the lever rod F, which should be made of wood) should be made of tin or thin metal, can be pivoted. These working parts have now to be cut out and pivoted in their correct positions. An inspection of the diagram will show what these parts are, what is their shape, what purpose they serve, and where they are pivoted and connected to each other. It will be noticed that in the diagram they are represented by the white portions.
