Schlesinger, of the University of Chicago "Deals with static electricity as funda- mental to an understanding of the mod- em theories of electricity. It explains how positive and negative electrification are produced and by animated drawings shows the part played by insulators and conductors. Natural photography supple- mented by animation gives an exposition of the movement of charges in the elec- troscope, the Compton electrometer, the static machine, and Nature's display of static electricity, lightning."

A few demonstrations follow showing the power of X-Rays to reveal the inner structure of opaque objects, such as wood, steel, cast iron, and even the hidden wheels of a clock. Scenes which show the action of the bones of the hand, wrist, elbow, knee, ankle, and foot, also views of the teeth, concluding with an X-Ray view of the entire body."
