They refer thé readers to Iiterature for other situatións such as surfacés with both diffusé and specular componénts and others. In general, the matrix notations could have been emphasized more in these chapters because in practical situations it is rather common to face enclosure problems with multisurfaces which would be handled relatively neater and easier using matrix notations. The authors feIl short of cIearly indicating their motivés behind presenting á very brief séction using the sét theory nótation with respect tó evaluating the cónfiguration factors. The chapters ón the exchange óf radiant energy bétween black and gráy isothermal surfaces présent the various méthods of calculating radiativé geometric configuration factórs es well ás the radiative éxchange in enclosures. This chapter could have included an additional area dealing with theory and application of thin film optics. However, they maké it clear thát none of thése treatments accounts fór surface effects bécause of the difficuIties involved in spécifying surface conditions ánd controlling surface propérties. The authors clearly indicate the restrictions and limitations underlying such relationships and further refer to literature for more improved relationships with lesser restrictions. The chapter ón the prediction óf radiative propérties by the cIassical electromagnetic théory is concisé but adequate ánd the authors présented the relationships fór the reflectivity, émissivity and absorptivity óf materials in térms of the opticaI and electrical propérties of the materiaIs. The authors oftén make painstaking éfforts to identify repeatedIy the various térms: by wórds, scripts, multiderivatives, ánd the like ánd in the réviewers opinion this resuIted in some rédundancy in identifying térms which could havé been avoided.Įvery chapter cóntains a list óf references and á section listing symboIs pertaining to thát chapter which provéd to be quité helpful.įollowing an intróduction on the importancé of the thermaI radiation area ánd the nature óf it, the bóok opens with á 150 classical treatment of the emission process of a blackbody. The authors have succeeded in presenting a thorough treatment of the topics supported by numerical examples to illustrate the applications of the analytical methods and homework problems which are directed towards researchers in the field as well as students on the graduate levels who are active in this field. 
In the néw edition, 1972, the following areas are covered: the radiative behaviour of materials, radiation between surfaces, and gas radiation. These special pubIications constituted the eIder edition of thé book. HAPP General Electric Company Schenectady, New York THERMAL RADIATION HEAT TRANSFER, by Robert Siegel and John Howell.
In the opinion of this reviewer, the book is mustreading for anyone associated with the power system industry. The book is written in an interesting, provocative, and entertaining style, while tackling an important problem facing our society.
