178 The Optical Magic Lantern Journal and Photographic Enlarger. Methylated Spirit instead of Kerosene.— About a fortnight ago a lantern exhibition was about to be given to the St. Clement’s Band of Hope, at Kinson. By some foolish mistake the lamp reservoir had been filled with methylated spirit instead of kerosene, and as soon as the lamp was lighted it exploded. A spade was procured, and on it the lantern was carried out of the hall and a bucket of water poured over it. Eventually the lamp was filled with kerosene, and again lighted, and as might have been expected under the circumstances, again exploded. The flames were again put out and the exhibition abandoned. ~ ~ ~ Jubilee Procession at Caleutta.—For some time past the cinematographic slides of the Jubilee procession, at the Theatre Royal, Calcutta, have been drawing large crowds. On the last day on which they were exhibited the children of the various schools, to the number of about 600, were provided with seats, and it proved a most interesting treat for the children. od ~ cod Holloway Social Union.—Weekly meetings of this Society are held on Wednesday evenings at 7.30, at Warlter’s Road Lecture Hall, Camden Road, Holloway, the following being some of the subjects announced, further particulars of which may be obtained from the Hon.

Slide-changing Device.—A patent bas been taken out by Mr. Newman, of,New York, U.S.A., for ‘a device for changing slides in an optical lantern.” A magazine in which a number of slides are arranged is furnished with a guideway connecting it with the slide stage, such guide-way being made telescopic. Spring catches bring the slides into the stage at the will | of the lecturer, who controls each movement by | pressing a ball. | tance off, all that is necessary being a small The lecturer can be any dis tube to reach from him to the lantern. It is claimed that by the use of this apparatus ee 6 have heard this story before, and in this country an inventor produced an appliance by which the lime was also turned by the same means whilst the slide was being changed, but all: this, though good in theory, does not in practice take the place of the operator. ot te % Acetylene.—The following notification, dated Oct. 15th, has been published in the London Guzette under date Oct. 19th, in substitution for that published in the Gazette on Oct. 15th :— ‘«Eixplosives Act, 1875.
