“ To publish so great a number of plates as one undivided work was considered unnecessary, for each subject tells its own story; and inexpedient, for it would defeat the object which the University had in view, and limit its acquisition to large Libraries, wealthy individuals, or Institutions where it would be beyond the reach of many who might desire to study it. ”

“ In the meanwhile he devised an automatic electro-photographic apparatus, for the purpose of making consecutive photographic exposures at regulated intervals of time or of distance. Some of the results of his experiments with this apparatus, which illustrated successive phases of the action of horses while walking, trotting, galloping, &c., were published in 1878, with the title of "The Horse in Motion." ”

“ After the last phase illustrated, the feet, during continuous motion, will revert practically to their position in the first phase.
The comparative distances of the feet from each other or from the ground are not drawn to scale ”

“ DESCRIPTION OF THE PLATES.
The results of this investigation are
Seven Hundred and Eighty-one Sheets of Illustrations, containing more than 20,000 figures of men, women, and children, animals and birds, actively engaged in walking, galloping, flying, working, jumping, fighting, dancing, playing at base-ball, cricket, and other athletic games, or other actions incidental to every-day life, which illustrate motion or the play of muscles. ”

“ It was considered inadvisable to make an arbitrary selection of the one hundred Plates offered to subscribers, and with the object of meeting, as far as possible, their diverse requirements, they are invited to make their own selection, either from the subjoined list of subjects, or from a detailed catalogue, which will be forwarded free of expense to every subscriber. ”

“ F, a horizontal battery of electro-photographic cameras, at any suitable angle to the lateral battery for a series of front foreshortenings.
O, the position of the electric batteries, a chronograph for recording the time intervals of exposures, and other apparatus used in the investigation.
A clock-work apparatus, set in motion at the will of the operator, distributed a series of electric currents, and synchronously effected consecutive exposures in each of the three batteries of cameras. ”

“ Copies of these photographs were deposited the same year in the Library of Congress at Washington, and some of them found their way to Berlin, London, Paris, Vienna, &c., where they were commented upon by the journals of the day.

In 1882, during a lecture on "The Science of Animal Locomotion in its relation to Design in Art," given at the Royal Institution (see Proceedings of the Royal Institution of Great Britain, March 13, 1882) , he exhibited the results of some of his experiments made during a few antecedent years at Palo Alto, California ”
