Photography in 1909.

In photography we find an interesting attempt to present moving pictures in colours by several inventors — Barrieelli, Friese-Greene, and Urban and Smith. Curiously enough, all three inventions are based upon the same principle of so rapidly presenting images coloured red, yellow and blue that the eye has no time to notice the successive presentations, and therefore combines them into one picture. In the same field of ehronophotography must be mentioned the important application of the moving-picture machine to the ultramicroscopic by Dr. Comandon, an application somewhat similar in principle to the combination of the ordinary microscope and kinetoscope made by Dr. Eobt. E. "Watkins of New York over ten years ago. Comandon's invention promises to be of considerable educational value in actually enabling us to see the struggles of our blood corpuscles with their microbic enemies.
