THE RING INDEX
A.C.S. Monograph No. 30 Second Edition, Completely Rewritten Casein production in the U. S. bas in the last decade leaped into an important position. Technical research on many new casein products has brought about sueh far-reaching changes in manufacturing processes that a second greatly expanded edition of this Monograph, originally published in 1027. became essential. In addition to increased use in the paper, leather and glue industries, three spectacular developments have tremendously enlarged the demand for casein, namely, plastics; casein paste print ; and casein libre, which may soon rival rayon in commercial importance. These recent developments are described in detail and critically evaluated. On the theoretical side great progress has been made toward a better understanding of this complex protein. The organic and physical chemistry of casein are discussed at length, and avenues for further research are opened up. CHAPTERS Introduction. Casein in Milk and Its Isolation, Frederick I.. Browne.

The (icof>hysical biboratory, Washington, I). ('. A.C.S. Monograph No. 77 Tin* swift emergence of glass from a sphere of limited utility to a position of emi'viice in which it is now challenging the supremacy of both stcvl and cotton makes this treatise on its properties indispensable t o all engineers, chemists and physi cists. The re sea re lies of the past two decades have resulted in important advnncesin our understanding of the constitution and structure of glass. Dr. Morey's book, more than 10 years in preparation, gives» detailed and critical discussions of all phases of the physios and chemistry of glass, including viscosity, heat capacity, optical and ehustic pro|KTtics, strength, hardness, etc. it deals fully will» the extent to which these and other properties are affected by t h e composition and annealing technique. The chapters, entitled respectively "The History of Gloss" and ,4 The Constitution of Cn tss" in themselves constitute a broad treatment of subjects-if general interest. The attempt has been made t o include ail measurements on glasses of Known composition. The many tables contain a wealth of valuable data. 561 Pages

A List of Ring Systems Used in Organic Chemistry By ArsTiN M. PATTBUSON* AM» I.KONWUO T. CVCKI.I.
l'util this book appeared in 1940 there was no single source in any language where the structutal formulas, names and numberings of the thousands of parent organic ring systems could be found. Even the latest edition of Ueilsteins Haiulbuch, with its supplements, doe> not contain half of them. Features of the Entries. The King Index li>t> over #/**/ ring systems. It covers the literature up to, and partly through, 1939. Here are some of the feature.·» for each ring system: (Ί ) A structural formula showing the standard num bering of the system according to rules drawn up for the Inter national I'nion of Chemistry. i'2\ Other numberings that have appeared in the literature. «.3» A serial number which serves to identify the system. (4) The preferred name and other names given to the system. (Λ) Literature references, including a reference to Beilstein if the system is described there. Arrangement. The ring systems are arranged from the simplest to the most complex, beginning with single rings, then systems of two rings, then those ot three rings and so on up to nineteen-ring complexes. If one knows the structure of a system he can easily find it in its proper place by one or two very simple rules. On the other hand, if one knows the name of a system he can quickly locate it through the very complete hulrx of Names at the back. The Introduction explains the features of the book and the principles on which the preferred names are constructed. The Appewlix reprints the Rules for Xumbering Ring Systems from the Journal of thp. American ( Vic/// ical Society.

Uses. Since there is no other similar compilation, the Ring Index is an indispensable reference work for organic chemists and for others who have to do with cyclic organic compounds. Some of its uses are: ( I ) Ascertaining the accepted structure of a ring system if the name is known. (2) Finding the name or names of the system if ι.»e structure is known. (3) Finding the numbering of a system. (4) Identifying a particular system if there are two or more isomeric forms, or if there is a confusion in names. (.">) Discovering what systems of a par ticular type have been reported in the literature, and where. (6) Naming and numbering a newly discovered ring system (7) As a reference book in teaching. Industrial applications. Organic chemistry, and in par ticular the chemistry of cyclic compounds, is playing a large part in chemical industry today. On this account the Ring Index should be in every industrial chemical library A.C.S. Monograph
