This was the planadopted in Anschiitz Electrical Tachyscope, exhibitedin i88g; but it is apparently impossible to discoverat what date Mr. Edison hit upon the same finally settled down to a form of instrumenthaving a one-slot shutter and continuously movingband; the exposure was consequently extremelybrief, and the waste of light involved by this arrange-ment rendered his apparatus as crude in itsprinciples as the first Phenakistoscope, though from CHBONO-PHOTOGllAFHY. 7& the point of view of mechanical accuracy it was amarvel. In many of its mechanical details, however, perfected Kinetoscope was unique, and a shortdescription of the apparatus, considered as a whole,will serve as a basis for their elucidation. Themechanism was contained in a cabinet furnished with. Fig. 75. an inspection opening at the top, as seen in Fig. cabinet was divided into three compartments, theone above extending over the whole width of the caseand containing the essential mechanism, the other twodivisions each occupying one-half of the lower side, shown in the drawing, contained a spool-bank accommodating an endless film, while the other 76 LIVING PICTURES. side enclosed the motive mechanism, which was naturallyelectric, that method of driving being well known asMr. Edisons favourite. The celluloid band was of thenow familiar form; that is to say, each margin wasperforated with four holes to every picture, thoughin 1890, when his pictures were smaller, Mr. Edisonused a single line of perforations only. This endlessperforated band passed from one side of the spool-bankto the other through the upper chamber, being stretched o
