complete so thst, generally, the original literature need not be consulted. The index lists all the labeled compounds mentioned in the text and indicates whether they are the product of a synthetic procedure or are employed aa reactants. The specificlabel(s) (e.g., W , ISN) are also clearly indicated. The book is not a textbook that covers the subject of isotopic labeling in a comprehensive manner. It is primarily a reference hook for the preparation of specifically labeled compounds. Research scientists in organic, biological, or pharmacological laboratories who are involved with the preparation of compounds labeled with the non-radioactive isotopes of carbon, nitrogen, and oxygen will find the book very useful.

This brief monograph is a thoroughly British contribution to the chemical fume hood literature, a subject on which there is little well oreanized information. I t is a litprature survrg and design srudy of "fume ruphoards" and fume dispersal swtems in and from laboratory buildings. Kxtensive il. lustrations, diagrams, and tables make available, with clarity, information on the design of the fume hood, the siting of the hood in the laboratory, as well as the design of the air supply and exhaust systems. Little recognition is given to recent American work nor are references t o such work included in the bibliography. Several examples illustrate the practical inforrnationcontained in th~monograph.In Secrion 1 on fumr cuphmrd design and ~ n stallar~onrhere iua iist~nrd t h e rnatrrlalsof construction for both warking surfaces and w& on the hoods shown in two illustrations.

This is an often overlooked consideration, It is useful to have this type of practical information available in collected form with the referenw nrovided.
