Franz Paul Liesegang (1926), (trans. Hermann Hecht, 1986), Dates and Sources, pp. 36-37.
The choreutoscope slide was designed by C. Beale in 1866. Its two forms featured the use of a hand-turned Maltese Cross mechanism to give multi-position slides the effect of continous motion. In the strip form, the interchangeable glass slide is moved through a metal holder with a window that allows one image to be veiwed at a time. In the disc form, a pulley rotates images on a mica disc; an intermittant metal shutter conceals the change in the image.
In 1884 W. C. Hughes was granted British patent number 13,372 of 9 October 1884 for a magic lantern slide carrier based on Beale's Choreutoscope. The idea was developed and a number of companies issued their own versions of the Choreutoscope slide, including J. H. Steward. Steward's name and copywright on the hand-painted slide suggests that the choreutoscope was probably made and marketed by Steward to Beale's pattern, and the engraved number 42 would also suggest that this is an early piece made in a limited number before Hughes' 1884 patent.
Two choreutoscope slides were sold in Magic Lanterns, Optical Toys and Cameras, 23 November 2000 and 11 may 2001, lots 116 and 106.
