Abstract

(1) MESSRS. Hewes and Seward's account of XVJL chart construction for engineering formulae consists of two main sections. The first 34 pages are somewhat general in character, and explain the formation of functional scales and the drawing of charts in general. The remaining 70 pages are devoted to the theory and practice of nomography. Both portions are well written, with a wealth of excellent diagrammatic illustration. The book is well printed and the charts well reproduced.
