PREFACE.

In the summer of 1892 while the Author was in California, preparing for a
Lecturing tour through Australia and India, he received an invitation from
the Fine Arts Commission of the World's Columbian Exposition to give a
series of Lectures on ZOOPRAXOGRAPHY in association with the Exposition now
being held in Chicago.

As these Lectures under the more familiar title of "The Science of Animal
Locomotion in Its Relation to Design in Art" had already been given at
nearly all the principal Institutions of Art, Science and Education in
Europe and in the United States, (see appendix A) the Author was induced to
believe that they might be repeated in a popular manner at the Exposition,
with some appreciation of the importance of the facts which his
investigation has revealed, not merely by the student of Nature or of Art,
but by that large and important class of students, known as the general
public.

Under this impression he delayed his far Occidental expedition and returned
to Chicago to find a commodious theater erected for this special purpose on
the grounds of the Exposition, to which the name of Zoopraxographical Hall
had been given; the Science of Zoopraxography having had its origin in the
Author's first experiments in 1872. It is not intended in this monograph to
give more than a synopsis of the usual course of Lectures on the subject,
nor to reproduce any of the pictured or sculptured representations which
are necessary for its proper elucidation, but merely to describe the common
methods of limb action adopted by quadrupeds--especially by the horse--in
their various acts of progressive motion, and to illustrate the most
important phases of these movements by tracings from the original
photogravures of the Author's work.

In the presentation of a Lecture on Zoopraxography the course usually
adopted is to project, much larger than the size of life upon a screen, a
series of the most important phases of some act of animal motion--the
stride of a horse, while galloping for example--which are analytically
described. These successive phases are then combined in the Zoopraxiscope,
which is set in motion, and a reproduction of the original movements of
life is distinctly visible to the audience.

With this apparatus, horse-races are reproduced with such fidelity that the
individual characteristics of the motion of every animal can readily be
seen; flocks of birds fly across the screen with every movement of their
wings clearly perceptible; two gladiators contend for victory with an
energy which would cause the arena to resound with wild applause, athletes
turn somersaults, and other actions by men, women and children, horses,
dogs, cats and wild animals, such as running, dancing, jumping, trotting
and kicking, are illustrated in the same manner. By this method of analysis
and synthesis the eye is taught how to observe and to distinguish the
differences between a true and a false
