The projection of pictures on a screen in such a way that they shall show relief, like that given by a stereoscope, has been accomplished by two methods, one of which depends on the use of polarized light, and the other on the use of color-filters. The following is an account of a modification of the latter method, which enables us to see the projected picture in relief, and at the same time in the original colors. A signal lantern is used.
