    "abstract": "The physical and photographic properties of the lenticular screen process of producing motion pictures in color, as developed by Berthon, and later known under the name Keller-Dorian and commercialized in the 16-mm. field under the name Kodacolor, are briefly described. The author traces the development of the process from the earlier mosaic screen process, and after giving consideration to the technical problems involved, indicates that the situation obtaining at present may be regarded as one stage of a development leading up to the application of the lenticular screen process to the 35-mm. field as well as the 16-mm. field.",
