The author has presented methods for the determination of some 20 elements found in various combinations in nan- ferrous metals and allays. The book is divided into 16 brief chapters; for ex- ample, Chapter 2, Ingot Copper, Chapter 14, Lead-Tin Solders, and Chapter 1, Special Reagents. The methods stress the use of colorimetric procedures, use of per- chlorie acid, mathematical eorreotion fac- tors, and directions for making several determinations orr Lhe ample (sequence procedures).

The tent essentinlly contains eookhook directions. In many places it is too hricf, and clarity has been sacrificed. One en- smple of eonriseness is the frequent state- ment "Deduct a blank." The eolorime& ric procedures contain poor or no direc- tions for the preparat,ion of calibration curves. One examplc of inconsistent directions appears on page 86: "Turn down the flame somewhat and move the flask to bhe edge of the hot plate." Per- hap8 the author refers to a gas hurner hot plate which is rarely used in modern laboratories.

This hook will serve an an aid to the analysis of nonferrous materials, although it is helieved that many of the procedures will present difficulty to the routine operator.

Research and process m~tallmgists know the vdne of an up-to-date edition of this standard work. It $so helongs on the 1ihrsr.y shelves consulted hy physical ohemistry ~tudents. No professor who has ~trllggled to m&e a sound phenomeno- logical baais for thermodynamics seem real to students can afford to overlook this prolific source of interesting examples taken from practical thermodynamics. Having worked such problems, students are hound to appreciate how ten minutes with a slide rule and free energy tables can save thousands of hours of costly trisl- and-error experimentation.

A departure from the original plan of Pascal's new treatise is noted in this vol- ume. Volume 11 was to have included the material on arsenic, antimony, h i s mnth, vanadium, niohium, tantalum, and protoactini~im hut the edit,or has decided to publish the data in t,wo volumes instead of one. For this reason, Volume 12 con- tains vanadium, niohium, tantalum, and protoactinium instead of the elements
