During the year 1917 I devoted almost constant study to the subject, and manufactured a crude model of a "Novagraph" camera, in fact, many crude models. I am quite sure were I afforded an opportunity to put a yard-stick on the raw stock used in my experimental work during that single year the gross footage would undoubtedly reach around the world.

In 1918 I was fortunate in perfecting a "Novagraph" camera capable of producing approximately 125 to 160 pictures per second, which went far to the realization of what I had hoped for.
In the latter part of 1918 and early in 1919 I so far perfected high-speed photography that the product of the cameras then available proved acceptable to the film distributors and met with hearty approval of the theatre-going public.
When "Analysis of Motion" first appeared on the screens of motion picture theatres they caused considerable amusement and very little serious interest on the part of the spectators. They were impressed with the sight of ball players, athletes, swimmers, divers,
