RT Journal T1 ORganic laboratory methods. JF Journal of the American Medical Association JO Journal of the American Medical Association YR 1929 FD February 16 VO 92 IS 7 SP 583 OP 583 DO 10.1001/jama.1929.02700330067033 UL http://dx.doi.org/10.1001/jama.1929.02700330067033 AB This is the translation of the first volume of the fifth edition of Lassar-Cohn's Arbeitsmethoden für Organisch-Chemische Laboratorien. The book is essentially what its title indicates. It discusses a wide range of laboratory procedures and includes many niceties of laboratory technic. The volume will be of value to the organic chemist who is synthesizing purifying and identifying compounds rather than to the individual whose problem it is to analyze any given material. The last chapter deals with ultimate analytic methods. There are no procedures described for the analysis of mixtures. A complete and handy bibliography increases the value of the book.
