"The Gospel of Relaxation" offers a model in the adaptation of scientific material to a lay audience, through the way in which the author makes clear the Lange-James Theory by concrete examples and practical applications.

CHARLES PROTEUS STEINMETZ (1865-), born in Breslau, Germany, was educated at Breslau, Berlin, and Zurich. For twenty-five years he has been Consulting Engineer to the General Electric Company, and for twenty years Professor of Electro-physics at Union University. Besides several authoritative volumes on subjects within his field, he is the author of America and the New Epoch (1906) and is a frequent contributor to literary as well as to technical journals.

"Science and Religion" may be used to show the student how even so technical a topic as the Einstein Theory may be rendered concrete for the general reader through analogy and specific examples.
