THE SCIENCE OF ZOOPRAXOGRAPHY. 

 Made Popular by Suggestive Tracings from "Animal Locomotion. 



A series of Fifty Engravings, each of which illus- 

 trates from 12 to 15 consecutive phases of some com- 

 plete movement, photographed from life. 



The successive phases of each action are arranged in 

 a circle nine inches in diameter; for reduced copies of 

 some of which see appendix A. 



Printed on six-ply Bristol-board and enclosed in

To convert the circles of figures into a 

 ZOOPRAXISCOPE, 

 cut out the disc, and, radiating from the centre thereof, 

 about midway from the margin, cut or stamp thirteen 

 equidistont perforations; each an inch long, and about 

 the sixteenth of an inch wide. 



Pin the centre of the disc to a handle and revolve it 

 in the direction of the arrow, at a distance of about 

 twenty-four inches, in front of a mirror. 



By looking through the tipper series of perforations 

 at the reflection of the lower series of figures, a sem- 

 blance of the original movements of life will be seen. 



The figures may be appropriately colored, and the 

 back of the cardboard disc should be painted a dark 

 color, or covered with a piece of dark surfaced paper 

 before cutting the perforations.
