NEW BOOKS quire an activation procedure which probably converts them t o nonstoichiometric oxides. The principal advantage of a prism monochromator ( p . 47) is the gain in energy obtained at short m-avelengths, but the basic design probleni with any monochromator is t o make effective use of its theoretical performance-the extent to which it is attained is usually determined by the geometry of the absorption part of the experiment-Le., the disposition of the source, burner, and associated lenses and stops. Instrument makers will hardly support the view (p. 5 2 ) that a double-beam system offers any financial advantage over a single beam, surely the cost of the extra optics far outweighs any saying on the electronics in these days of cheap stabiliser systems. These however are minor criticisms. Chapters 3 and 4 on analytical parameters and applications, respectively, are exceedingly good. The section on recommended procedures is coniprehensive and well documented. The descriptions of commercial equipnient are incomplete, but this is probably a criticism of the manufacturers' publicity departments rather than of the author! Particularly welcome is Chapter 5 which deals with o d l a t o r strengths, vacuum ultraviolet lines, and atomic fluorescence. This is up to date and most interesting. The book as a whole is eminently readable and is m l l produced, being pleasingly free from typographical errors. The price, S9.i5, seems a little high wen by today's standards, and this may deter chemists from purchasing individual copies, but the book should, I think, find a place in all laboratories where atomic absorption techniques are used or contemplated.

Ultraviolet a n d Visible Absorption Spectra. Index for 1960-1 963.
This volume is the third in the series ‘Ultraviolet and Visible Absorption Spectra.” It provides a four-year supplement Fvitli more than 25,000 references to spectra published during 1960-63. Sixty-six journals and one collection of spectra in book forni are covered. Also included are references t o optical rotatory dispersion and circular dichroism spectra.
This Atlas has been published in collaboration with the Photoelectric Spectometry Group, London, and the Institut fur Spektrochemie und Sngemandte Spektroskopie, Dortmund. Information is given in both English and German. The Atlas consists of a carefully selected collection of solution spectra of compounds containing typical chromophoric groups, supplemented by tables showing the effects of substituents and solvents. Included are sections dealing with biologically important compounds, inorganic systems of interest t o organic chemists, spectrophotometric standards and solrents, in addition t o surveys of chromophoric groups.
