book reviews treatment of ionic equilibria where i t would seem t o belong. Bronsted and Lewis acids are well defined and illustrated. The sect,ion on complex ions, while i t relates well t h e geometry of complexes t o hybridized orbitals, is very deficient in nomenclature of complexes and in ligand field Lheory. I n general this reviewer considers the work to be an excellent, programmedlearning text. However there should be a n index so that st,udents could look up specific information. Some topics might be better organized (e.g., acid-base), and topics do not progress in difficulty a t the same rate. The book might be improved with more exercises in ionic equilibria. of various types. Rote programmed learning must be snpplemented with hist,oricsl and descriptive material by lecture and reference readings t o insure proper context. There are no problems for homework assignments. We have fonnd t h a t s t u d e n t , ~do chafe m d e r the questionanswer proceduw of x programmed text, especially if they are trained in rapid reading; often they must bc advised to learn to skip aver repebitious qnestions. Programmed learning will probably not meet the needs of most freshman chemistry courses. Able students e m cover most of the book in one semester, as we do in our honors course. The book can be highly recommended to the deficient stndent in need of supplementary helps as an excellent if expensive drill aid.
Those familiar with his other textbooks will recognize Slater's distinctively lucid and incisive style of writing. Characteristically, he emphasizes physical and intuitive lines of reasoning in preference to elegant mathematics. All in all, he bas produced anolher book of considerable value, bath t o beginners and to mare experienced teachers and research workers.

Ten or fifteen years ago, many physical chemisls longed for a revised edition of Pauling and Wilson's classic "Int,roduetion t o Quantum Mechanics," first poblished in 1835. Today, this need appears t,o have been fulfilled by a. wide variet,y of texts, ranging from simple qualitative discitssions to more detailed expositions of theory and comp,~tat,ionalmethods. This text by Professor Rehutte is a n additional altempt to introduce chemistry students to t h e theory and uses of quantum mechanics. ~ a r t i c u l a r l vas a ~ o l i e dt , atomic ~
