more profound treatment. Instability theories and transition from laminar to turbulent flow have not been considered, not as a11 oversight, but intentionally. The effect of comnressibilitv" of the fluid on turbulence phenomena has been briefly mentioned. The material in Chapter 1 (General Introduction and Concepts) gives a general introduction to turbulence theories and derives the basic relations which are used later. Chapter 2 (Principles of Methods and Techniques in the Measurement of Turbulent Flows) is quite an extensive treatment of the methods of measurement and serves to familiarize the research engineer with many existing methods and their merits. In Chapter 3 (Isotropic Turbulence), the general theories are developed on this subject. This is perhaps the best written portion of the book. In Chapter 4 (Nonisotropic Turbulence) the author tells about the recent attempts to arrive a t a statistical theory since theoretical knowledge of noniso. tropic turbulence is so much lessadvanced. Chapter 5 (Transport Processes in Turbulent Flow) covers thetreatment of theoretical and experimental investigations on transport processes. The last two chapters ( 6 . Nonisotropic Free Turbulence, and 7, Sonisotropic "Wall" Turbulence) fully round out a well presented treatise on the subject. The Appendix contains a short introduction to the Cartesian tensors which is particularly valuable in view of the rather extensive use made of tensor notation and tensor calculus. A complete tomcnclature is conveniently added a t the end of each chapter and each chapter has; fairly complete list of references. If your interest is in the field of fluid mechanics, or borders thisarea, then you'll need a copy offhis book on your per library shelf.

Ibert Mellan and Eleanor Mellan Chemical Publishing Co , Inc , Vem York, 1959 96 pp. $4 50 This book presents rules and directions for the removal of some 300 spots and stains "effectively and economically." It *as written both for the homemaker and the professional cleaner and includes m e chapters. The book contains no index, yet lists the itams in Chapter 9 in alphabetical order Examples are aeroplane glue, berry stains, gravy, nail polish, and wood stains Each entry includes information on equipment a n d directions for the stain removal. The 23 stain removing agents are easily available and include ammonium 'droxide, acetic acid, amyi acetate, :inera1 oil, and ink remover. The four chapters include brief descriptions of the types of material, dyes and stain and means for their identification.
BOOK REVIEWS The book is well written and non-technical, and wouldbe a welcome addition to every home library. It i8 unfortunate that t,hr high price of this hook will probably limit its sale; a paper-hound edition should scll ;if ;i 1rsct.inn of lhii ""st.

An accounting of specific ore processing mills and their methods is found in Chapter 5, and Metallurgical Extraction and The Refining of Zinc are found in Chapters 6 and 7. The Manufacture of Zinc Oxide and Industrial Zinc Oxide, Zinc Sulfide and Other Zinc Compound8 arc discussed in Chapters 8 and 12. Chapter 9 includes the many methods by which zinc is applied and used as a protective coating and as a protective cathode. Zinc as an alloying agent and its use in the metallurgical extraction of other metals are taken up in Chapters 10 and 11. The last two chapters are devoted to the Biological Significance of Zinc and the use of Zinc in Wood Preservation and in Agriculture. As in any volume with multiple cont,ributors, 52 in this case, the presentation is uneven and there is eonsidcrable duplication from section to section. The equation for the reduction of zinc oxide wit,h carbon monoxide appears about ten times and the reverse reaction about five times. The chemist will find conventions and st,atements which arc not palatable such as the use of atomic oxygen in equations for the weathering of sulfide minerals, a. valency of six for zinc, "strong affinity bct,ween zinc (combined) and copper ions," "copper bars. . , soluble in acid (non oxidizing) spray from cells," "sodium, potassium. . . huild up sufficient to displacezinc in solution," "zinc sub fate appears to suppress the ionization of cobalt sulfate," "more caustic acids," salammoniac, "molecules" of Zn(NH3),C!;;, manganese peroxide (MnOe) and others.
