Calculus a modern approach

"Calculus a modern approach. Second, enlarged edition, mimeographed. The Bookstore, Illinois Institute of Technology, Chicago 1953, title page + xxiii + 1 + 303 pp.
This book is intended both as a textbook and as a treatise. It contains an account of the author's theory of variable quantities (see preceding review), which makes it the first textbook on calculus which the reviewer has seen, which gives an explicit analysis of what is involved when the pure mathematical theory of functions is applied to physical problems. The book has many other novel features, and is written in a lively, challenging style; but we shall here comment only on those aspects which bring the work within the scope of this .
