86 REVIEW REVIEW. EXPERIMENTAL ORGANIC CHEMISTRY. By JAMES F. NORRIS, PH.D. Pp. vii + 215. Publishers : McGraw-Hill Book Co. (Inc.), 239, West 39th Primarily intended as a laboratory guide in elementary experimental work for the student of organic chemistry, this little book goes far to justify the claims of its author. I n many respects it shows originality in scope and treatment of the subjects dealt with, whilst at the same time it includes the greater number of the organic preparations with which the junior student is expected to be familiar. As the author bas made no attempt to confine himself to the syllabus of any particular examina- tion the ground covered is naturally wider than is usually the case in textbooks of a similar type.The chapter on ‘‘ Laboratory Methods ” is quite a useful one, and the descrip- tions of apparatus employed and of the processes suggested for qualitative organic analysis are both clear and concise.In sucoeeding chapters the preparation and reactions of a great variety of organic substances are given, including both aliphatic and aromatic compounds. Nost of the methods described are good, and contain all the essential detail of manipulation that the student would require to know.Due emphasis is laid on the important point, so often forgotten by the worker, that he should not be satisfied with merely obtaining a small specimen of each particular substance, but should ascertain the theoretical yield and how far the weight of his product falls short of this. The concluding chapters contain the preparation of one or two dyes, together with somewhat brief accounts of pyridine compounds and a few proteins. The book, ae already mentioned, covers a rather wide range of subjects, and very probably the fact that the last few chapters will not be required in an elementary course justifies their brevity. At any rate, the work as whole is one that may very fairly be recommended for the purpose for which it is intended. Price 5s. 2d. net. Street, New York, and 6, Bouverie Street, London, E.C. 1915. P.
