"Interesting and instructive to all."--New York Herald.

"Highly interesting and valuable for every lover of horses."--Illustrirte Zeitung, Berlin.

"We cannot more fittingly conclude our review than by repeating our recommendation of the work to all artistic and scientific bodies."--The Nation, New York.

"So perfect was the synthesis that a dog in the lecture room barked and endeavored to chase the phantom horses as they galloped across the screen."--Berkeley Weekly News.

"Noted artists, such as Menzel, Knaus, Begas; eminent scientists, such as von Helmholtz, Siemens and Förster and even the imperturbable field-marshal, Count von Moltke, were enthusiastic in their applause."--Illustrirte Zeitung.

"A very large number could not obtain admission, so great was the desire to hear the lecture.... A wonderful surprise even to the careful observer of Nature."--Die Press, Vienna.

"The lecture was received with stormy applause."--Berliner Post, Berlin.

"The lecture was given in a popular manner, with scientific accuracy and artistic taste.... The room was filled to the last corner; nearly all the Royal Family and the Ministers were present."--Münchener Neueste Nachrichten, Munich.

"After attending Mr. Muybridge's demonstrations, we felt no surprise at his having been received so enthusiastically in Paris."--Berliner Tageblatt, Berlin.

"The lectures of Mr. Muybridge are unquestionably the most intensely interesting we ever listened to. No one in Berlin should fail to attend them."--Norddeutsch Allgem Zeitung, Berlin.

"Some lectures are too technical for the general public. Here is one in which everybody is interested. The Lecture Theatre was crammed to repletion; we thought a few vacant places might have been reserved for those whose pleasant duty it is to record the brilliant success of Mr. Muybridge."--Pall Mall Budget, London.

"So great an interest did the demonstrations excite that Mr. Muybridge was unanimously requested to repeat them. Two days afterward this distinguished company, including the venerable Field-Marshal (Count von Moltke) himself, attended a repetition of the lecture."--Illustrirte Zeitung.

APPENDIX B.

ANIMAL LOCOMOTION.

DESCRIPTION OF THE PLATES.

The results of the investigation executed for the University of Pennsylvania 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.

These sheets of illustrations are conventionally called "plates."

EACH PLATE IS COMPLETE IN ITSELF WITHOUT REFERENCE TO ANY OTHER PLATE,

and illustrates the successive phases of a single action, photographed with automatic electro-photographic apparatus at regulated and accurately recorded intervals of time, consecutively from one point of view; or, consecutively AND synchronously from two, or from three points of view.

A series of twelve consecutive exposures, from each of the three points of view, are represented by an outline tracing on a small scale of plate 579, a complete stride of a horse walking; the intervals of exposures are recorded as being one hundred and twenty-six one-thousandths of a second.

When one of the series of foreshortenings is made at a right angle with the lateral series the arrangement of the phases is usually thus:

1 2 3 4 5 6 7 8 9 10 11 12 Laterals.

1 2 3 4 5 6 7 8 9 10 11 12 Rear Foreshortenings from points of view on the same vertical line, at an angle of 90 deg. from the Laterals.

1 2 3 4 5 6 7 8 9 10 11 12 Front Foreshortenings from points of view on the same horizontal plane, at suitable angles from the Laterals.

The plates are not photographs in the common acceptation of the word, but are printed in PERMANENT INK, from gelatinised copper-plates, by the New York Photo-Gravure Company, on thick linen plate-paper.
