| THE MACHINE (HALF ACTUAL SIZE) SOME IMPORTANT USERS and Some Opinions No one will question the great value of the 'slow motion' cinematograph picture in certain studies. !!! THE ASHDOWN ROTOSCOPE gives this service, at a very low cost, in Engineering Research. Ascertaining and keeping check of high speeds by hitherto known methods is difficult, dangerous, and uncertain. !!! THE ASHDOWN ROTOSCOPE will secure these speeds immediately, accurately, and without making contact. GOVERNMENTAL The Admiralty. War Office. Air Ministry. General Post Office.

Its portability, and the fact that no elaborate special arrangements have to be rigged up, make it very convenient." —A leading Telegraph Engineering Company. "A most ingenious invention."—A popular Professor of Science. "Our Camera Works have found your Rotoscope of considerable value to them, and they are ordering another instrument for one of their other departments." —World famous Photographic Company. "A very effective device."—A Television Expert. "I am using the Rotoscope almost entirely to get slow-motion pictures of moving mechanisms, and the machine suits my purpose very well." —An important Telephone Engineer. "The most practical form in which the Stroboscope has ever appeared."—A Competitor. "The Ashdown Rotoscope is a great instrument, and it came up to scratch on all the trials yesterday. On the 3,000 r.p.m. mill it showed me just what I wanted to know." —A well-known Consulting Engineer. SHOWN WITH 'HETEROPTIC' SHUTTER FITTED.
