solved in a clear, concise manner. Answers are given to about half of the large numher of problems, (a good pedagogic practice). Where appropriate, ionic oquatiana are used throughout the text. Tho authors digress from this practice occasionally, e.g., neutralieation of phosphoric acid an page 103. A more extensive discussion of the single-pan balance would be in order because of its wide use in industry. The authors devote only one short paragraph to its discussion. The titretian of calcium with NDTA is hardly t,ho same kind of complex ion titration as cyanide with silver. Thc treatment d buffer solutions could be more extensive bemuse of their importance to chemistry and in natural processes. The conciseness of presentation along with the breadth of coverage of material show painstaking care on the part of the authors to condense the basic elements of the field in s moderately sized text. Previous editions of the text h a w made this book one widely used in elementary quantitative analysis courses; the present edition willcertainly keep it among the leaders in the field. This book can be recommended to all teachers of quantitative analysis for their careful consideration. GLENN H. BROWN U ~ r v ~ n s t or r r CINOWNATI CINCINNATI. Omo

IN REVIEWING the first edition (See J . CHEW.EUUC.,30, 270 (1953)), i t was stated that the hook represented an excellent review of the textile industry. This holds true for the second edition. However the new edition has not changed as much as the industry in the int,ervening years, in spite of the numerous changes and additions reflecting the newer synthetic fibers and the newer auxiliary chemicals made by the authors. Part I discusses the Nature and Processing of Fahrics in eight chapters. I t is this part which gives such a fine, concise picture of the whole industry. A new chapter on felts and nonwoven fabrics has been added to this section. Part I1 treats the chemicals used in the indust1.y. Nine chapters are concerned with chemicals. water. som.
water-resistants, mothproofing agents, etc. The previous review states: "The coverage in each field is quite adequate, written ior the chemist, not the specialist in the psrtirular field. T h e fact that

trade names arc so frequently mentioned will be of value to many workers. I t should be noted that the names arealways those used in industry, not those known to the retail trade so the teacher of Home Economics vill he helped less than the worker in thc textile industry." The new d t i o n announces market cstimates are a new feature which should he most vnluahle. Like the first edition, thc hook contains canrise, accurate, n-ell-witton data. on practically every use of chemicals in the ohemical procefising industry.

"Tae purpose of bhis book is to present eeonomie and design principles as applied in chemical engineering processes and operations. The expression plant design connotes indostrid applications; eonsequently, the dollar sign must always he kept in mind when carrying out the design of a plant." Dr. Peters has devoted the first third of the hook to applied economics and the remainder of the hook to methods and important factors in design of plants and equipment. The first sectinn (170 pages) on economies consists of nine chapters: introduction, costs in chemical processes, interest and investment costs, tares and insurance, depreciation, alternative investments and replacements, cost estimation, east and asset accounting, optimum design. The second section (272 pages) on fmt,ors in design consists of eight chapters: general design considerations, waste disposal and treatment, the design report, equipment design and fabrication, materials handling and and costs transfer equipment-design heat transfer equipment-dc~ign and costs, mass transfer equipment-design and costs, filters and miscellaneous equipment-design and costs. Appendix A lists three major design prohlems, three minor desim oroblems and ten oracticeweights, ronnversion factors, specific gravities and the like. The book is recommended for a one-or twosemester ronrse for advanced undergraduates or graduate chemical engineers. Kevertheless the chapters on equipment design give the elementary and hasio equations thzt these students should (Contint~edon page A508)
