later ohapter has included a new section on the production of heavy water. The chapter an Chemical Separation and Processing has incorporated the chapter of the first edition entitled Semration Techniques of Nuclear Engineering. I t includes design concepts of hot cells, dry boxes and manipulators. The last chapter of the second edition is an entirely new chapter on Thermanuclear Power, and gives the theoretical basis for these processes. This is certainly a needed addition to complete a. text on nuclear engineering. In summary it can be stated that the second edition of this text hrings together much more information than was available a t the time of printing of the first edition. Much of this added information was released a t the 1955 Geneva Conference. Already the second such conference (1958 Geneva Conference) has been held this year and additional information has been made available. Thus, in this rapidly expanding field of nuclear engineering, this seoand edition will certainly help to build the framework upon which suhsequent editions will be required to bring the text continually up-to-date.

The approach of this text is direct and Eollows the classical subdivision of suhject matter. The style is clear and friendly. Chapters are short and exercises and literature citations generally good and well placed. Average students will find the text helpful and there is enough material to challenge the reasonably good student, but not the exceptional one. The teacher who uses this text will find it easy to schedule his lectures to cover the one year course, and, by relying heavily on the text, will he able to place emphasis in class on selected points, rather than feeling that he must transmit to the student set of notes to serve as the mrtjor basis for the course.

Carl Wilhelm Scheele-The Chemist
Apothecary

Carl Wilhelm Scheele (1742-1786) is a formidable candidate for the honor of the mast fruitful chemist. He, like Mozart in music, touched d l branches of his field in s. life that covered only a few decades and left immortal traces of his activities. There is no full-length biography of this gifted chemist-apothecary hut essays concerning his life and rtchievements are many. The present sketch was first issued in 1942 and has been but slightly modified in this edition. As stated in the subtitle, the illustrations are an integral part of t,he text and hence are provided with ample legends. For the most part these illustrations are taken from the exeelknt Scheele biography by Otto Zekert issued between 1931 and 1935 by the Gesellschaft fiir Genehichte der Pharmasie. The present author has done his work well. He has given in 10 pages an exoellent condensed account of Scheele's life and accomplishments written in a readable and interesting style. Since the volume was sponsored by pharmaceutical houses and pharmscists, it is not surprising that stress is laid on the fact that Scheele came into chemistry from pharmacy and spent his entire life, from his apprenticeship on, in various apothecary shops. Scheele's own words give evidence of his pride in his profession: "I am doing my chemical research only as a sideline in order not to neglect my duty in my apothecary shop." A special section (2 pages) is devoted to a summary of Scheele's achievements. This is taken predominantly from the esmy (1894) included in T. E. Thorpe's "Essays in Historical Chemistry." A
