by a series of parallel grooves B B, and on the opposite side with a series of prisms C C, separated by grooves D D, the prisms on each side being substantially parallel to each other. I have illustrated the prisms as being of a particular angle, but the essential feature of my design is the prism-light provided on both sides with a series of substantially parallel prisms, separated by a series of substantially parallel grooves.     I claim--     The design for an ornamental prism-light as herein shown and described.
