30 REVIEW REVIEW. ELEMENTARY QUALITATIVE ANALYSIS. By BENTON DALES, Ph.D., and OSCAR LEONARD BARNEBEY, Ph.D. Pp. viii+205. John Wiley and Sons, New York; Chapman and Hall, Ltd., London. 1916. Price 5s. 6d. net. The authors state in their preface that this boob is intended to act as a guide in qualitative analysis for students who have previously carried out a year's course of work in general chemistry.The book, as its title implies, deals with the subject in quite an elementary manner, but with some innovations that would seem to have little to recommend them. For instance, it is difficult to see anything but disadvantage in fhe arrange- ment of the special reactions €or bases, not under the names of the latter, but in paragraphs 'headed with the formulae of the reagents giving characteristic precipitates.The authors also suggest that the acids present in a mixture should be defected before the bases; and although occasionally such a procedure may be found de- sirable, this is not. usually the case. The descriptions of the various reactions and tests are given concisely and clearly, but the detection tables are rather lacking in this respect, and, together with the general arrangement referred to above, this fact will probably militate against the general use of this book in teaching laboratories in this country.
