Excerpt from Journal of the Society of Motion Picture Engineers, Vol. 26: January June, 1936 After reviewing the theoretical conditions for accurate reconstruction of the binocular visual image, the practicability of the system using polarized ana glyphs is demon strated and the advantages of stereo and its probable use in education discussed. The conclusions here presented embody the first results of an inves tigation along practical lines made at the instance of the Carnegie Corporation and forming a part of the Corporation's carefully con sidered program to stimulate and improve education in the fine arts. The writer was chosen to guide this particular project in its initial stages for the reason that, over a considerable number of years, in connection with research in the field of Italian sculpture at Smith College and under the auspices of that College in Italy, he had had the most exacting practical experience in the photography of objects of art, and had been active in the publication of these studies in a series of volumes illustrated by actual photographic prints.
