This pioneering work is unusual in several respects, not the least of which is the vast amount of material collected by the combiied efforts of many investigators over a relatively short period of time. One is immediately impressed with the great care the authors have taken to present their problems and sources of error and with the voluminous data that are included. MIRIAM P.
