000 square-foot chemistry building wish that we had had this book before. The contributors combine to make a total of many years of daily experiences in their respective laboratories and of visits to others. Architects who have the responsibility of site locations, building arrangements according to functions, traffic flow patterns, modular dimensions as related to laboratory uses, and proper distribution of electrical and mechanical services should buy this book. Its seven major sections are: Organization for Planning and Construction, General and Specific Considerations, Health and Safety Factors, Applications in Design, Laboratories for the Academic Functions, Specific Laboratory Planning, and Recent Laboratory Construction. Because of increasing health hazards of working with more poisonous and radioactive chemicals, the health hazard section is presented in some detail. It seems that there might have been more depth at the expense of so much breadth. A chemical engineering laboratory at Ohio State University is described in much detail, but there is no such detailed analytical data for chemical laboratories. Some of the older academic laboratories such as Frick at Princeton should have been compared in some detail with a new one like the James Bryant Conant Laboratories at Harvard. Also, recent industry laboratories such as Ciba and Merck 'at Summit and Railway, N.J., respectively, should have been given detailed consideration. There is also some tendency toward duplication such as the description of bench top materials. Some sections were too brief and others, such as radiological labs, were a bit lengthy. The list of constructions from 1951 to 1961 contains some glaring omissions. For instance, the University of Georgia has recently spent nearly $8 million for a Science Center. This is probably one of the most expensive academic undertakings in the country during this 10-year period. Also, insofar as chemical engineering buildings are concerned, Mississippi State lias the best in the South. Of course, the larger ones at Ohio State, Wisconsin, Michigan, and MIT are more elaborate and more expensively constructed. An error was instantly spotted just by cursory examination of these references of 1951-61 construction. The 1951 physical chemistry laboratory, mentioned on page
467, should have been listed as being at Missouri rather than at Mississippi. On page 282 there were two errors spotted. "In Figure 11.31 the preparation is done immediately behind the lecturer." Actually, this description is of Princeton University laboratory, shown in 11.30. In the next paragraph there is a similar mistake. But most of these shortcomings are minor. All in all, the authors, the National Research Council, and the publishers are to be commended. Someone has said that maybe future editions should be divided into an Allgemeine Teil and a Spezielle Teil. The latter part should almost be rewritten in each new edition. With more and more new scientific buildings each year there should be many new editions of this basically fine book.

It's true. In-process viscosity measurement is the most direct progress report of many chemical reactions that you can obtain. In polymerization reactions, for example, Brookfield process-mounted Viscometran units eliminate the need for constant sampling, assure greater product uniformity and guard against run-away reactions. Like color, pH and stability the viscosity of any material is a vital property, a fundamental measurement, which can be easily and accurately evaluated and controlled with low-investment Brookfield instrumentation. If you would like to know more about the profitable role of viscosity control in your processes, write today for complete technical information. There is no obligation,
