on Applications of X-Ray Analysis held in August I960 at the University of Denver, appear in Volume 4 of Adnances in X-Ray Analysis. Volumes 1 to 3 of Advances in X-Ray Analysis contain the proceedings of the 1957, 1958, and 1959 conferences (See page 71 A, Dec. 1960). This continuing series provides a valuable reference both to the researcher engaged in x-ray analysis and to the beginner who needs to develop competence quickly. Volume 4 contains discussions of theory and new instrumentation, com bined with data on important applica tions. Papers dealing with crystal structure are correlated with new tech niques for trace analysis of minerals. Other topics of interest include electron probe research and x-ray microscopy in geological morphology as well as phase transformation in refractory alloys, and in studies at cryogenic and at extremely high temperatures.
