PORTABLE ELECTRIC FILM-SLIDE LANTERNS (Patent applied for) As this system may be new to some, we should like to explain its advan- tages, and offer some advice to those who propose to employ it. Designed and Manufactured solely by The Slides are printed by photography on a strip of Film (non-inflam- mable) and turning a handle brings them all on the screen in turn. To change NEWTON & Co. Ltd. the picture when desired, you merely turn the handle. At first the lanterns were so made that they required unpacking and fitting up, and the light needed centring and adjusting, etc., like an ordinary The Film-Slide method of illustrating Talks and Lectures to small lantern ; but later lanterns were made of which the " Unit " was perhaps audiences is now so much used, owing to its economy—the price of the Slides the most satisfactory, which were built into their cases from which they are being Id.

The following six Sets of New Film-Slides have been published with the assistance of the Rev. T. E. R. Phillips, M.A., late President of the Royal "Universal" Film-Slide Lanterns Astronomical Society, to illustrate a complete Course of Six New Lectures written by him, which contain a clear and succinct résumé of the astronomical knowledge of to-day. They are illustrated by many recent copyright photo- graphs from the most famous Observatories in the world.
