Many of the chapters have been almost completely rewritten and the following methods appear which are not given in the second edition: 1. The Determination of Mercury, Microelectrolysis. 2. The Microacetyl Determination. 3. The Determination of the Molecular Weight: (a) By the method of Rieche, b By the method of Rast, (6) Of liquids by the method of A. Soltys. 4.

The purpose of the manual is to provide a series of experiments which can be mcirdinated with any standard textbook on general chemistry. In the words of the authors, "By judicious selection from the experimental material offered, an instructor can organize a practical course of elementary general chemistry to meet any reasonable requirement." The twelve reprintings indicate that they have been very successful in accomplishing this purpose. The first chapter is taken up with detailed instructions for general laboratory procedures and practices. Chapters 11 to XVII contain experiments on the Kws ohshi (Neorganicheskoi) Khimi. common elements and their usual reCourse in Inorganic Chemistry. PROF. actions. with one chapter on ionization. B. N.

omitted, such as the instructions in regard to side shelves, store room, distilled water, and miaosmpe. Obviously such directions would apply to hut one laboratory, and for all others would he useless. The approach to the study of the metals by way of qualitative analysis is unusual. The general type of laboratory manual is inadequate in this part, and this arrangement would seem to be much better. Even if the student does not pursue a further course in analytical chemistry he will have a working knowledge of the readions of the metals and their interrelation, prouided he has the time to complee tk work ouflined. The amount of material given in the hook is far too much to be covered in one course, and. as noted above, the authors do not intend it to he, but many laboratory directors experience di5culty in making a "judicious selection" without interrupting the continuity of the general scheme. The directions are clear and explicit. The printing is plain and on paper that will hold ink. The authors have wisely omitted giving directions for procedure which a student of only average intelligence can easily determine far himself. Perhaps this is the greatest merit of the hook. The student must do more than record a column of one-word answers to a series of questions. He must do some thinking. He also will have opportunities to make "discoveries" for himself, instead of being told beforehand just what e m result will be. The book is also adequate far students in a second-year general chemistry laboratory course where such students do not expect to make chemistry their major, hut desire same knowledge of the analytical and organic side.

1. What are the conclusions of America's leaders of research? 2. What practical results are they achieving in their laboratories? 3. What is their opinion of ceperative effort in research as contrasted with individual effort? 4. How should the Research Department he organized? 5. What is the philosophy and method of operation of research laboratories in specific industries?
