In these essays, the author tries to set forth, as clearly as possible, certain fundamental principles, together with their practical application to the life of his time. Some of these principles were stated, more briefly and technically, in Ellis's larger Studies of sex; others were therein implied but only to be read between the lines. Here they are expressed in simple language and with some detail.

The aim of this volume is to provide, without too technical detail, information of value to anyone concerned with the operation, the maintenance and the repair of electric locomotives. The fundamental units and principles of electrical science in general are explained and, in addition to descriptions and illustrations of electric locomotive design and construction, there are included examples of the practical solution of problems as encountered in the electrification of steam railway properties. There is also appended a brief history of the electrification of steam railroads in the United States--Adapted from preface.

Ludwig Prandtl was a pioneer in the development of rigorous systematic mathematical analyses applied to the science of aerodynamics, which have come to form the basis of the applied science of aeronautical engineering. In the 1920s he developed the mathematical basis for the fundamental principles of subsonic aerodynamics in particular; and in general up to and including transonic velocities. His studies identified the boundary layer, thin-airfoils, and lifting-line theories. The Prandtl number, measuring ratio of momentum diffusivity (kinematic viscosity) to thermal diffusivity, was named after him.

Edwin Littlefield writes that he has arrived safely in San Francisco. He has received the cargo, and thinks it will be suitable for the current market, despite his opinion that "the majority of people here have left their honor & principles at home."
