Book Notices This is Liquid Sugar. A Technical Guide for the Liquid Sugar User. Refined Syrups & Sugars, Inc., Yonkers, New York, 1955. VII 205 pp. 15.5 x 23 cm. A monograph on "liquid sugar" describing production, testing, properties, and commercial applications of the generally saturated aqueous solutions of sugar (sucrose, invert, or mixtures of both). "Syrup" is often used synonymously with "liquid sugar," but they are distinguished industrially by the U. S. Sugar Act definition of a liquid sugar as a solution containing less than six per cent soluble nonsugar solids. Technical data on specific gravity, density equivalents, turbidity, alteration of concentration, determinatioh of saturation relations of sucrose, invert sugar and water, viscosity and boiling points, are tabulated in the appendix.

Particularly useful is the appendix which contains the names of various sources of supply for the material needed in the preparation of the various formulas listed. This book deserves a place on the shelves of every drug store.
