reason perhaps is owing t o the incredible wealth of facts and detailed information available an the chemistry of sulfur and selenium compounds. Nevertheless, this work has a more decided charm and fascination in its own right, due to the excellent systematic organization and the exhamtive treatment of the subject.

the cheriiral reactions of the compounds of this class. The reactions likewise are illustrated with typical laboratory dircctions for selected model compounds. The second division (295 pp.) of this volume surveys the ehemistry of selenium and tellurium compounds. The preparation and reactions of the following classes are considered: cyanogen compounds of selenium and tellurium as synthetic intermediates, R-SeH, R-TeH, R-Se-R, R-Te-R, R-Se-S-R, R-Te-Te--R, polyselenides and analogous mixed compounds with sulfur, selenium, and tellurium, a variety of oxygen eontaining acids of selenium and tellurium and their derivatives, selenium and tellurium derivatives of carbon dioxide and earhonic acid, selenium and tellurium derivatives of carhonyl compounds, and selenium derivatives of carbaxylie acids. The concluding chapter deals with the general problem of systematic nomenclature of sulfur compounds. One needs only to recall the widespread use of sulfur compounds as dyes, pharmaceuticals, rodent poisons, inseoticides, plant protective agents, detergents, textile treatments, rubber chemicals, softening agents, moth proofing, tanning agents, etc., to recognize the signifioant contribution of an encyclopedic work of this nature. The literature has been covered up t o 1954 or 1955, the date being indicated a t the beginning of each section. Some idea of the extent to which the literature has been surveyed will be gained from the fact that this volumo contains about 14,000 references. The subject index has approximately 7500 entries. Tbis volume is an outstandine m o n o ~ r m hon the chemistrv of the sulfur, selenium, and t k u r i u m compounds which wiil find a singularly appreciative audience of all serious investigators in this field.
Chemistry of the Nucleus, which has been rather extensively rewitten and expanded by six pages. The exercises a t the end of each chapter have been revised. Tho book is very well written and shows evidence of its many years of success as a college text. I t is replete with small hut effective illustrations. The inorganic interest of the authors manifests itself in unusually complete accounts of the descriptive chemistry of the elements. Kearly ane-third of the book is devoted to the metals. In bath the fourth and fifth editions a rather extecsive list of references for additional rcading in jourO F CHEMICAL EDUCATION, I n d t a t k l and nals such as JOURNAL Engineering Chemislq,, Chewirnl and Engineering Neus is given a t the end of each e h s ~ t e r . These articles are a t an a ~ o r o m i a t e to interest and st,imulate t,he mork able level and should student of general chemistry. The genwal development of the book will make it useful for students with or without high-school chemistry. The exercises provided appear adequate although there are rather few solved problerr~given as examples. The treatment of chemical equilibrium is woven into the chapters on Solutions, Hydrogen, Chlorine, etc., with the emphasis generally less than found in many current texts. Ionic equations are used sparingly. The authors prefer the oxidation number method for balancing oxidation-reduction equations. The half-reaction method is not presented. I t is noted that the authors still retain illinium to designate element 61 in their periodio table (although it is indicated that "Cyclonium and Promethium have been suggested for the synthetic form of element 61") and on page 679 in reference to its formation in atomic piles.

THIStext presents adequately the necessary information for an elementary course in qualitative analysis. I t is divided into two parts. The first part prssents the necessary fundamentals of chemistry such as ionization constants, solubility constants, complex ions, etc. The second part gives the laboratory procedures and reactions for both cations and anions, including procedures for the phosphate ion in cation analysis and thioacetamide precipitations.
