Geology and Mineralogy. 167 



David White, Monograph, vol. xxxvii, U. S. Geological Survey, 

 pp. 1—467, plates i-lxxiii, 1899. — The material upon which this 

 monograph is based was collected from the Coal Measures of 

 Henry County, Missouri, by Dr. J. H. Britts of Clinton, Mo., and 

 by Mr. Gilbert Vanlngen and Dr. W. P. Jenney of the U. S. 

 Geological Survey. The whole flora has been exhaustively 

 studied, many new species described, and the old species sub- 

 jected to careful criticism and revision. 



Comparison of the flora with those of other regions in the 

 United States and other countries has led to the following deter- 

 minations of correlation of horizon for the Missouri flora, viz : 

 " The Lower Coal Measures of Missouri, as represented by the 

 coals of Henry County, were laid down soon after the Morris 

 coal of Illinois, though probably earlier than the Upper Kittan- 

 ning of western Pennsylvania, or very likely about the time of 

 the formation of the D coal in the Northern Anthracite field." 



In the European sections, close affinity is found between this 

 flora and that of the zone of Bully-Grenay in the Valenciennes 

 Basin, but as the author remarks, the fauna is perhaps in a meas- 

 ure transitional, " while it is probably contemporaneous with a 

 portion at least of the upper zone of the Valenciennes Basin, as 

 presented in the basins of Commentry or the Saar, ... it may 

 represent a slight paleontological transgression on the Stephanian 

 ('Houiller superieur')." It is represented in Silesia and Bohemia 

 by the Schatzlar and Radnitzer Schichten, and corresponds with 

 the "Transition Series" of Great Britain. w. 



5. La Face de la Terre {Das Antlitz der Erde) par Ed. Suess, 

 translated by Emmanuel de Margeeie, vol. ii, pits. 1 and 2, 

 figs. 1-128, pp. 1-878. Paris, 1900 (Armand Colin & Cie).— 

 Those familiar with the original edition ot Professor Suess' Ant- 

 litz der Erde will not need to be reminded of the extreme value 

 of the Erench edition, the second volume of which has recently 

 appeared. It furnishes a store-house of information regarding the 

 structure of the land surfaces and the geological structure of the 

 earth not met with elsewhere, except as distributed in a very 

 large number of publications. The first volume has already been 

 noticed in this Journal (see vol. v, p. 152). In the translation, 

 M. de Margerie has had the assistance of MM. Bernard, Deperet, 

 Kilian, Poirault, Six and Zimmerman. The translations are 

 admirably made, and the editors have added 85 new cuts to the 

 French edition. These are many of them charts, and add much 

 to the value of the volume. The translators have also added, in 

 foot-notes, a large number of new references to literature, bring- 

 ing the bibliography up to 1899, which will increase the value of 

 the book for investigators. The present volume discusses the 

 oceans and the geological conditions of the land and ocean sur- 

 faces during the Paleozoic, the Mesozoic, the Tertiary ; and in 

 the latter part of the volume, a number of chapters are devoted 

 to special subjects, such as the Temple of Serapis, Baltic and 

 North Seas, the Mediterranean during historic period, etc. w.
