the scientific tools and methods wed and of the reaults of the more important branches of research on coal. Although no critical commenta by the editor are included, the benefit of his appraisal is inherent in the selection and arrangement of the articles. There are only a few typographical errors. Perhaps the most aeriow one occum in article No. 15 on Coal Petrology by C. A. Seyler. On pages 257 and 288, the equation RO 0.28 X l . W R should have been written Ra = 0.23 X (1.363)NR.This article by C. A. Seyler is also the moat difficult for the reader to understand and evaluate. The method of presentation of data in Figure 2 is difficult to comprehend, and the reader ie not informed that repeated efforts by competent coal petrographers to duplicate Peyler’s work have not shown the existence of nine components of separate and distinct reflectivity. All of the articles present an excellent selection of references to original sources of data; and for thoae desiring a very brief, readable account of coal reaearch this book is highly recommended.
