Abstract

This volume by an English author is written for engineers in the heating and ventilating field. The book is a compilation of a number of lectures the author delivered before the National Institute of Industrial Physiology on Heating and Ventilating. The author has assembled considerable significant information within the 401 pages, much of which should be of interest to hospital managers, engineers and architects of medical institutions.

The book is well illustrated, has a large number of charts, graphs and tables to assist the engineer in calculating heating and ventilating problems.

A portion of the book is given over to discussion of air-borne bacteria and the use of ozone in the ventilating systems. The writer comes to the conclusion that in the light of present day evidence the ultraviolet radiation and the disinfectant vapors or mists are ineffective against bacteria carried by gross particles such as dust. Furthermore, he concludes
