through holes in its sides to see the moving image of the illustrated band
below the slits on the cylinder’s interior.

magic lantern. Th e early zoopraxiscope presented a continuously moving row
of images, and the later zoopraxiscope presented a series of quickly passing
shuttered views of single frames.Copyright 2010 Cengage Learning. All Rights Reserved. May not be copied, scanned, or duplicated, in whole or in part. Due to electronic rights, some third party content may be suppressed from the eBook and/or eChapter(s).
