Aspherical bottle, filled with water, was placed between theelectric arc and the lens to act as condenser, Fig. 4. Thebottle B was encased in a metal cylinder E, fixed to thefront of the lantern A by four rods, each terminating ina screw V. The metal cylinder E was continued forwardsin the form of a tube F, the end of which was fitted witha hinged shutter G carrying a small piece of ground glassH. When the film was set in motion this hinged shutterwas lifted and laid back upon the top of the tube to whichit was attached. The spherical bottle, which was filled with distilled 46 MOVING PICTURES chap. water to which a few drops of acetic acid were added, actedin exactly the same way as the glass condenser of it possessed this advantage.
