The Photographic News 17 March 1882, p.137

"I should like to see your boxing pictures," said the Prince of Wales to Mr. Muybridge on Monday at the Royal Institution, when the galloping horse, the running deer, the trotting bull, the halting pig, and the racing dogs had successively crossed the screen in life-like measure. "I shall be very happy to show them, your Royal Highness," responded the clever photographer; and promptly there was thrown upon the screen two athletes, who pounded away at one another right merrily, to the infinite delight of the audience in general and the Prince of Wales in particular.

Mr. Muybridge, in this case, had taken rapid successive pictures of a pair of boxers as they assumed one fighting position after another, and then these photographs were rapidly thrown on the screen in the same order by means of his zoepractiscope. This a boxing-match was reproduced in all its photographic reality. "I don't know that these pictures teach us anything useful," said Mr. Muybridge, "but they are generally found amusing."

Mr. Muybridge's "boxing match" may call to mind the steam engine in motion, of which we ourselves secured a photograph in 1870, when working with Sir Charles Wheatstone. Sir Charles had invented an instrument similar to Mr. Muybridge's zoepractiscope, and asked our aid to furnish the necessary pictures. We produced two series, one of a steam-engine, and another of an infantry soldier going through the bayonet exercise. Our work, however, was very simple compared to Mr. Muybridge's. To secure the steam-engine in motion, we merely had to produce thirteen photographs; the engine was at rest, and we simply turned the fly-wheel one-thirteenth of a revolution between each picture. The result many of our readers may have seen; the engine moved, but rather slowly, as if it were slackening speed.
