The value of the preparations is twofold: not only do they afford approved methods for the synthesis of needed "ausgangsmaterial" but their study gives valuable hints as to the technic of organic readions. F. B. D A ~ N S UNNB-Y

Organic chemists always welcome each new volume in this series, which has become one of the valuable contributions of America to this field of chemistry. The present issue contains thirty-one preparations from some twenty laboratories, mainly university-among the foreign ones are found Freiburg, Miinster, and Vienna. The list follows: Acrolein Acetal, a-Aminoisobutvric Acid, 1min no-2-Naphthol ~ydrochloride, 1Amino - 2 - Naphthol - 4 - Sulfonic Acid, Azuxybenacne, a-Bromoisuvaleric Acid, Eromomesitylcnc. 8-Chlurupropionaldchyde ~ c e t a l ,Citraconic Anhydride and Citraconic Acid, Cyanogen Bromide, 2,4Diaminotoluene, Ethyl Ethylenetetracarbornlate, Ethyl Phenylcyanopyruvate, Ethyl Pimelate, Fumaric Acid, dl-Glyceric Aldehyde, dl-Glyceric Aldehyde Acetal. Haptaldoxime, n-Heptyiamine, 9-Iodoaniline, Isodurene, Itaconic Anhydride and Itaconic Add. Mesaconic Acid. 3-Methyl Pentamic Acid, a-Naphthoic Acid, nPentane, Symmetrical and Unsymmetrical o-Phythalyl Chlorides, iro-Propyl Thiocyanate, Thiohenzaphenane,o-ToluicAcid, ~ r i e t h y lCarbinol. It might be noted that the syntheses of ethyl pimelate and fnmaric acid are interesting illustrations of the formation of open chain derivatives from ring compounds.

$2.25. Another book of qualitative analysis. Considering the Limited number of elements whose detection is taken care of by the ordinary qualitative scheme it seems that the possible number of combinations and permutations would soon be reached. But, just as artists in ages past have been painting faces with a limited number of features and have produced no two alike, so analysts have written and are writing their qualitative texts and no two are alike. Each has some features that appeal t o us, and some that do not. Some books like the masterpieces of art appeal favorably t o the majority of us and are acclaimed a new step, a great advance. Now, here is a new book built around the framework of the old familiar hydrogen sulfide separation. I t contains preliminary experiments on each of the ions so that the beginner may learn what a certain precipitate ought to look like and how it ought t o behave. I t contains plenty of theoretical matter (142 pages) so that be may learn why and under what conditions a reaction occurs. As the author states in the preface, the methods and principles which make up the book are those which the author has used in his dasses for many years. Also, the study of the theories and principles of electrolytic solutions serves as an intraduction t o physical chemistry for the chemistry major or as a source of knowledge of many of the most fundamental concepts of theoretical chemistry for the
