The text is devoid of all)- description of labomtory techniques, and the instructor would have to describe and demonstrate d l such operations. There is a reasonable distribution between classical and instrumental procedures. There are fourteen experiments using titrimetrir techniques (including eleetrometrie titrations), four experimeuts using gravimetric techniques (including one eleetrolytic separation); five experiments using colorimetric methods; and one ion exchange experiment. Specific experiments include: determination of the solubility product of lead thiocyanste, determius, tion of zinc with EDTA, and the colorimetric determination of chromium and manganese in steel. The directions for t,he experiments are reasonably well written. The index to the text has t,oo few entries; a t least. twice as many are needed. A minor objection is found in t,he layout of the pages in the text. The large amount of space between paragraphs, the lack of paragraph indentation, and the lack of boldface type used for the naming of the topics and subtopics may result in some confusion t o the reader.
