By STANLEY B. ELLIOTT

Ass't to the President, The Ferro Chemical Corp., Subsidiary of Ferro Enamel Corp., Cleveland, Ohio

A. C. S. Monograph No. 103

A comprehensive, capably written treatise on metallic soaps, designed to acquaint research chemists and tech­nologists in the petroleum, paint and lubricant industries with the properties, formulation, method of manufacture and utility of these industrially important materials. In addition to the main treatment of the subject, six appendices on patents, specifications and applications are included. Because it is the only book in English to bring all this di­versified information together for ready reference, this book will be a valuable addition to technical libraries as well as an essential reference work for workers in fields which it covers.

The Weather-Ometer brings weathering conditions right into your laboratory. A few weeks testing with control-able cycles of light, water spray, and selected temperature and humidity equals years of actual outdoor exposure. The Weather-Ometer is safe to operate automatically 24 hours a day without attention.

Used all over the world — Atlas Weather-Ometers, Launder-Ometers, and Fade-Ometers.
