392 and of vitamin Bn. The occurrence in saliva of something related to the intrinsic factor is not mentioned. A long chapter by B. B. Lloyd and H. M. Sinclair deals with vitamin C and includes the various theories as well as the proved facts of its funotiming. This concludes Volume I. In Volume I1 there are two chapters by G. H. Bourne on histological aspects of vitamin physiology and a chapter by G. W. Kidder on nutrition of invertebrate animals. Of the twelve chapters in this volume, the one by G. D. Navelli and M. Soodak on coenzymes is particularly uuaeful because it gathers together a wealth of detailed information on a complex subject. There are three chapters on the metabolism of inorganic elements. The h a 1 cbrtpter, by G. A. Goldsmith, summarizes the applications of nutritional discoveries to human nutrition. Disooveriea in the science of nutrition ooour so rapidly that older hooks on the subject tend to be out of date. A new and well planned treatise of this sort is therefore very welcome to all who sre interested in this subject that is fundamental for human welfare.

There are about one hundred specific tests in addition to much materid on general procedures. The emphasis is on environmental and particularly airborne contamination. Tahle 5 in the Appendix is the Threshold Limit Values as adopted by the American Conference of Industrial Hygienists, though for the year 1952. Tahle 7 is a useful outline, listing for ahout a hundred materials collecting media, sampling apparatus, sampling rate, analytical method, and page reference. The bibliography lists 114 references to the literature which are included in the general subject index for the manual, This is an Interscience Manual, one of four ins. proposed series of laboratory manuals, and is an excellent example of a usefut presentation by competent authors.

MARGINAL PUNCHED CARDS IN COLLEGE AND RESEARCH LIBRARIES Howard F. McGaw. The Scarecrow Press, Washington. 1952. 218 pp. Illustrated. 13.5 X 6 an. $4.50. THISbook describes and illustrates edge-notched punched cards and equipment supplied by each of various manufacturers as well as bssie sorting techniques and a variety of coding methods. About two-thirds of the hook is devoted to detailed description and illustration of library spplications. The circulation, acquisitions, serials, reference, bindery, and other departments are cavered. In an appendix are listed the libraries using edge-notched punched cards. The right-hand margins of the printed pages are not justified. The illustratione are poor. An ineonvenienoe is that footnotes are Listed at the end of each chapter along with literature cite+ tians. A bibliography of 87 references is given a t the end of the book. The author's objectives are: "First, to provide 8. guide book to the librarian just beginning his exploration of the uses of marginal punched cards and, second, to call to the attention of those who have been working with such cards, some of the tecbniques and applications about which they possibly have not heard." These objectives are fulfilled. ROBERT S. CASEY
A QUALIFIED British investigator has here reduced a. lnrgu volume of information on antibiotics to a short, authoritative, and highly readable and interesting text. Following as it does the publication by others of detailed reviews, monographs, and bandbooks devoted to antibiotio substances, Robinson's book p r o sents an abbreviated but satisfying picture of the subject as a. whole and one that should be especially valuable to students of biochemistry and bacteriology. Major emphasis is placed on the chemistry and biochemistry of the heat known antibiotics (penicillin, streptomycin, ehloramphenicol, aureamycin, terramyein). Bxteriologieal applications are restricted largely to summation of mtimierobial spectra, and the discussions include short sections on pharmacology and clinie d applications. Very briof notice is given a180 to additional antibiotics svnthesiaed hv aetinamvoetes and hv bacteria: for

To a degree it serves to supplement certain information made available in earlier reviews and already antiquated by the current pace of antibiotic research.
