This textbook aims to point out physical science teachers and others interested in experimentation the usefulness of the Magic Lantern, and especially of the Porte Lumiere, and a few other pieces of apparatus which can mostly be extemporized for physics instruction as well as art and other science instruction. Experiments are included. No attempt has been made to explain phenomena as other books do that, but it is hoped that a sufficient number and variety of experiments are plainly described to make readers familiar with the art of projecting.
