Leadbeater, who showed ordinary single and _ bi-unial patterns ; also lanterns for vertical projection and photo-micrography. A number of very choice (old) hand-drawn and painted slides : were handed round, aud a promise was given | that later in the season they should be exhibited on the screen. = m a New Cinematograph Films, etc. — Messrs. West and Son have just introduced some 18 new film pictures consisting of field gun drill, torpedo explosions, attacks and defence by sailors, E.M.S. ‘Crescent,’ and many other naval subjects of interest, including about six of yacht racing scenes. These pictures were lately exhibited at Portland Hall, Southsea. house was crowded, and the audience were delighted. The sole London agents for these subjects are Messrs. Watson and Sons, who have also obtained the sole copyright of a series of 50 pictures for their publication as ‘‘ Lantern Slides of Captive Wild Animals,” taken by Mr. Gambier Bolton. The Company lately made arrangements to photo graph the ceremonies at Amsterdam connection with the coronation and other fétes, and within 24 hours were able to in London. The length of film used was 1,400 feet. Messrs. Fuerst Bros. are now ina position to supply the following films, either Lumiere or Edison gauge: Macdonald’s Egyptian Brigade and the Charge of the 21st Hussars (now the 21st Lancers). baad baad od The Ashton-under-Lyne Photographic |.

Warwick Trading | The : A Serious Oxy-Acetylene Ex MONG the questions receivad during the past few days, we have one from a reader in foreign parts, asking for the cause of a serious explosion he lately had at his studio. As the subject is one of public interest, a) especially to those who, far away from all opportunity of receiving cylinders | of compressed oxygen, make their own gas and ' use it from a tank on the gasometer principle, it is to be hoped that some who may be placed in a similar position may profit by the experience of others—we will give full details. In one corner of the studio in question, stood a small gas tank of about 5 feet capacity into ' which oxygen gas had from time to time been conducted, so as to be, as it were, on tap for certain lantern exhibitions, this during the five years which it had been in use having been found a convenient method of storing the gas (cylinders of compressed gas not being obtainable in that part of the world). The subject of acetylene gas being extensively dealt with in the Maaic LANYrERN JOURNAL, IE a it was to be expected that our friend would try it as an illuminant, so he sent to one of our | advertisers for a small acetylene generator, and blicl hibi : pmecae / in due course this reached its destination. publicly exhibit these cinematographic pictures | supply of acetylene was generated and about A 2 feet stored in the tank spoken of, which had for some considerable time previous been standing empty. An opportunity for using the acetylene, excepting a short trial, did not present itself for about five days, but so far everything was right and the gas was used up. The day following it became necessary to use the oxyhydrogen light for some experiments, and for the storing of the oxygen the aforesaid tank had again to be brought into requisition, but before charging it, the interior of the gasometer was filled with water, the top of the bell portion being covered with same in order to ‘‘remove’’ all acetylene gas. About 3 feet of oxygen gas were then The lantern with applied at the hydrogen side of jet; the flame Ives | given by this was, we are informed, not nearly so large as had been usually obtained, but this | the user attributed to the intense cold which | prevailed, the thermometer standing at the time at 38 degrees. Suddenly one of tbe | rubber tubes blew off with a loud report and the
