Muybridge had settled down in 1885 with a position at the University of Pennsylvania, where he took many pictures with the same battery system, borrowing, however, some ideas about the studio arrangements from Marey. Muybridge never improved his technique or realized that such a cumbersome method could not produce satisfactory results. This did not seem to disturb him for there is no evidence that he sought large screen projection of the magic shadows before audiences. In February 1886, Muybridge visited Edison at his New Jersey laboratory and showed him plates of successive motion pictures, or, more accurately, a succession of stills of various phases of the same action. When Muybridge lectured at the London Institution in the Fall of 1889 a complete report was published in the _British Journal of Photography_ for December 20, 1889, in an article by W. P. Adams. From this we learn that Muybridge was then using a simple projector fitted with a gear system which revolved before the lens a glass disk of some fifteen inches in diameter on which the photos were mounted; in front of this was a zinc shutter disk with radial slits totalling one more than the number of pictures, in order to give a forward motion to the figures. That was the old Plateau magic disk idea. With the same number of openings in the shutter as pictures, the figures would appear to move their arms and legs and yet stay in the same place; if less shutter openings, there would be an appearance of backward motion. “The disks are rotated at the same speed in opposite directions, and the figures rapidly following each other appear on the screen as a continuous movement of the animal,” the English reviewer remarked. Muybridge showed slow and normal action motion. The subjects included a mule kicking, a woman emptying a pail of water, a girl walking down steps carrying a breakfast cup and saucer, and what was said to be the best of all, a little girl finding and picking up a doll. In passing, we may note that in addition to singling out Meissonier for praise, Muybridge asserted that the Japanese were far ahead of everyone else in representing motion in art! Muybridge eventually retired to his native Kingston, England, after winning fame through his work in America. But he obtained more than fame, for he was able to leave a considerable sum of money, in addition to his instruments, to the local museum. Efforts to locate the Muybridge instruments at the Kingston-on-Thames Museum in 1943 were unsuccessful. In 1889, Thomas A. Edison, already working on the problem of motion pictures for a year or two, visited the Exposition at Paris and there met Marey who showed him the results obtained with his methods of motion photography, and the reproduction of the scene with a Plateau-disk combined with a projector and the disk illuminated by an electric Geissler tube.
