[a. F. praxinoscope (M. Reynaud), irreg. f. Gr. πρᾶξις action + -scope.]
A scientific toy resembling the zoetrope, in which a series of pictures, representing consecutive positions of a moving body, are arranged along the inner circumference of a cylindrical or polygonal box open at the top, and having in the middle a corresponding series of mirrors in which the pictures are reflected; when the box is rapidly revolved, the successive reflexions blend and produce the impression of an actually moving object.
