these have been included in separate chapters a t the points where the material can he studied to the best advantage. This is avowedly an elementary text. The laboratory experiments have been selected t o illustrate the basic techniques and principles. The lahoratory directions have been written in such a manner that the student can follow them with a minimum of supervision. The hook has heen arranged so that either gravimetric or volumetric analysis can be given first. . The hook can readily beused either for a half year or for a year course." The second edition contains seven additional determinations. Certain passages have been clarified or expanded. Additional self-examination questions have been included. A welcome addition is provided by 178 problems. Answers are given for the first several examples in each set. The problems are numbered consecutively throughout the entire book, a great convenience that might well be adopted by other writers. The first edition (1940) contained xi 246 pages, 15 X 23 m. The present edition has 60 pages mare. The type size and the printed area on each page are identical in both editions. Nevertheless, the 1944 edition weighs only 520 grams as opposed to 720 grams. The economy was achieved by trimming the excessive margins and by using a lighter paper. The net result is a much handier volume. I t is hoped that this improvement will not be discarded when the present paper restrictions are no longer a compelling factor. The American colleges have evolved a fairly standard course in beginning quantitative analysis. Quite a few texts are now available to fit this syllabus. An instructor can choose any of the half dozen better ones quite a t random and not make a serious error. "Booth and Darnerell" can be included in this company. Much thought, careful planning, and Gatured pedagogical experience have manifestly gone into this text. The laboratory directions are exceptionally ludd and heavy type has been effectively used to aid the student through the maze of the procedures. Particular emphasis has been laid on the calihration of weights and volumetric equipment. . The text will serve well the needs of those who wish to learn or teach the fundamentals of quantitative analysis. It should not be expected t o do more. RALPHE. OESPER Umvms~rvDP CINONNATJ

The major changes made arc: ( a ) arlvanccmcnt of the treatment of the ras lows from the appendix to (.nit 11; i b ) addition of srctions "11 Ramlr's law, and crystal form and structure; (c) expansion of the unit on organic compounds; (d) added discussion of the less common elements such as Be, Ti, Zr, Th, Se, Te, and Ge. I n addition, there has been a mnderate amount of rewriting t o improve clarity or t o include recent discoveries, although snrprisingly enough there is no mention of the extraction of either Mg or Br from sea water. This is still a simple text. Many teachers, probably a majority. are blessed with students who are none too well prepared in high-school science and mathematics. For such, some of the encyclopedic tests that have appeared in recent years are much too stiff a dose. Whether or not, as may be argued, it is the fault of the secondary schools, the fact remains that we must provide some instruction in chemistry for less than top-flight students. For such, here is a conservative text, followinga well-beaten path successfully, well written, interesting. T o turn b r i d y t o faults, now, what littie hair remains t o this reviewer stood on end a t reading the following (p. 5): "We should (finally) have a single molecule of the substance, this time a molecule of sodium chloride. A single molecule of table salt would he so light that it could not be a solid substance. I t would be a molecule of sodium chloride gas." Other eyebrow raisers are: "The non-luminous gas flame is much hotter than the luminous one" (p. 7). "one liter = 1000 cc." (p. 512), and theflat-bottomed flask shown in Fig. 117 for an experiment similar to the ammonia fountain. [See E. C. WEAVER. "Laboratory accidents." J.
