LABORATORY GLASSBLOWING

INTHE preface to this small volume the authors state "Herein are given instructions which they hope will enable any reasonably dextrous person to acquire sufficient skill not only to execute repairs to broken glassware, but also t o make quite complicated glass apparatus." Their

estimate of a reasonably "dextrous person" is perhaps revealed in a delightful summary to Chapter 4. "All the operations we have described can he carried out in a morning or afternoon, by which time you will have learned quit8 a lot of fundamentals of glassh1owing:-how to cut and clean glass; how to draw points; close the end of a tube; and make flanges . . . WL:hope you will also have acquired . . .preparalion, patience, and persevemnee." The hook is written largely from the point of view of a n English laboratory worker which may limit its value for use in the United States. Thus, nothing is said about the problem of operating glass blowing burners with natural rather than manufactured gas. Most of the instructions are for working "soft" or "lime" glass. The best parts of the hook are the chapters on metal-glass seals and stopcocks. Through some error, the table of contents lists a seven-page Appendix which is not included in the body of thl: hoak.

INA day when much research is done in research institutions, the professional glassblower is one of the many skilled persons who plays an important role in the day-to-day work of the chemist. This might be taken to mean that a working scientist should not spend time training himself to iashion equipment from glass. The authors of this small volume, however, believe that tthe laboratory scientist should he prepared to carry on even in the face of limitations in the service provided for him. Further, they regard lahoratory work rts a craft vital to the continuing of fruitful scientific discovery. They observe, "In modern times the old tradition that the masters of science ~ h o u l dalso be themselves masters of the practical craft of science has failed to persist, and the more eminent scientists are now usually not t o he found a t the working bench in the research laboratory. There is, we think, n consequent weakening of the craft basis of practical ~cientificwork, and some r e treat from the view expressed by I . Lang-

muir that work in the laboratory can be fun." This trend is viewed with alarm. The suggestion is made that there are a variety of ways by which a relatively untrained person can produce useful laboratory equipment from glass. Several chapters are devoted to descriptions of types of glasses and equipment which are useful for laboratory glass working. For the American worker these chapters will serve to relate materials available in England t o those commonly available in the United States. With this information, the fact that the book is largely written from the point of view of English laboratory practice and products will not prove a serious disadvantage. A good deal of emphasis is put on the use of a. hand torch as a simplhied procedure for many operations. Possibly more amateur glass workers need to explore this as an effective aid to forming seals with a minimum demand on manual dexterity. One example which the authors fail to mention is the use of B hand torch and blow tube in removing pinholes from assembled appsrstus. What may well prove most valuahle for many workers already somewhat familiar with glass working techniques are several chapters on special procedures for sealing metal to glass, sealing different kinds of glass together, and handling large diameter tubing. A long chapter is devoted to eanstruetion of pieces of apparatus and will prove helpful not only for its directions for making pieces of useful equipment but also for suggestions on solving various common kinds of problems in glass manipulation. The reviewer believes that the authors should have described the simplest form of water cooled condenser to construct, namely the "West" type, in addition t o the three tvnes nresented. The book concludes wit< 's. hAef discussion of methods for manipulating fused quartz. LAURENCE E . STRONG E.,RL~*MC O L L E ~ Z RICHMOND. INDIILT*

THE second edition of this masterly volume which covers all the ramifications of ohemical literature and its use is essential far any serious study in a chemioal library. As the most recent publication in the field of chemical literature, the bibliographical material is the most nearly up-to-date colleotion of titles now available. Eight ohapters have been retained. They are Problems and Objectives, Books, Periodicals, Patents, Other Sources, Indexes, Libraries and Procedure in Literature Searches. The chapter on Other Sources mentions addresses, biographies, bibliographies, committee findings, lectures, motion pictures, museums, organi-

zations, personal correspondenoe, scientific meetings, theses, unpublished material and some literature from related sciences. The lists of reference books, hooks on special topics, abstract journals and general journals have been classified (with annotations for the important journals) into nearly the same groups as the sections in Chemical Abstracb. Two new chapters, Trade Literature and federal, atate and foreign government publications, hsve been added. Far all the chemical fields, the most important encyolopedias, treatises and speoial titles and their location have been included. Journals and translation services for them are given. The valuable appendixes include a bibliography of chomical literature reference books, a comprehensive list of symbols and abbreviations used by American and foreign publications, names of important chemical library collections, names of older periodicals, scientific and technical organizations, book dealers and publishers. In the past thirty years since the first edition was published, the Special Libraries Association personnel has prepared many useful compilations for hoth general science and chemistry alone. The Division of Chemical Literature of the American Chemical Society is now in existence. Unusual care has been takeken by the authors t o inolude all the tools prepared by these organizations that are valuable for the scientific librarian. This broadens the scope of the suggested source material to include less familiar but nevertheless pertinent publications hoth old and new, reference titles not designed for chemists alone, and foreign abstracting services. The excellent o h ~ p t e ron chemical indexes has been extended to teach the art of their use with illustrations of the type of assistance needed t o recognize difficulties. The recommended procedure to make a literature search for limited or extensive problems is presented in detail. This includes the types of records to employ, mechanical aids and their sdvantages, and a list of books far study of technical writing. Little that might be of a~tssistaneein the examination and creation of chemical literature has been omitted. This edition is a. worthy successor to the first.

This edition of Dr. Amow's text book on chemistry for nurses includes an intraduction to organic and inorganic chemistry as well as physiologioal chemistry and is thus suitable for use in the training of nurses

who may have no previous college courses in general chemistry. I t s success in this field is attested by its passage into this fifth edition. The lines of the previous edition are followed in that application of chemistry especially t o clinical medicine are emphasized for the purpose of maintaining the student interest. I t has been brought up t o date by brief discussions of many recent physiological developments of clinical interest, also tables listing subatomic particles, common organic radicals, precious stones, and clinically important constituents of human blood.

DR. SZMANThas contributed a r e freshingly new approach to the presentation of organic chemistry, both in organization and description. The factors which make this book different from other organic chemistry texts include: (1) an expanded introduction giving an excellent review of electronic configuration, chemi d bonding, hybridieation, and electronegativity; (2) an early presentat,ion (Chapter 2) of the concept of resonance; (3) an extensive introduction t o the principal types of organic compounds (Chapter 3); and (4) s, unique orgsniestion of the classes of organic compounds in the main body of the text. The book is divided into three parts. (Continued on page A5C6) JOURNAL OF CHEMICAL EDUCATION
