ENGINEERING MANUAL.

Edited by JohnH. Perry and Robert H. Perry '45. NewYork: McGraw-Hill, 1959. $9.50.

An engineer frequently finds himself cerebrating in areas of engineering where the general principles are vaguely familiar but the data and methods are not. This manual has been designed for such a person. It is a compendium of authentic, accurate, and useful information germane to the oldest established categories of engineering, civil, mechanical, electrical, and chemical, as well as architectural and nuclear engineering.

This manual is something more than a Cook's tour of these areas of engineering knowledge. The information, prepared by experts, is generally introduced by an exposition of fundamental principles, a presentation of general equations and their reduction to special equations of particular use to engineers. This, from a fundamentalist point of view, is a fine feature of the manual and should make it attractive to well-educated engineering students.

For the utilitarian, by choice or compulsion, there is presented in condensed form, a surprising amount of up-to-date design information in these wide ranging fields of engineering. Its use is facilitated by a profusion of homographs and chart solutions of conventional problems encountered.

The manual is arranged according to the engineering categories mentioned. It is extensively cross-referenced to minimize the duplication of material and keep the book to suit-coat-pocket size. There are sections covering mathematics, mathematical tables, as well as physical and chemical data of interest to engineers.
