8. Miner alogiscJie Tabellen; by P. Groth and K. Mieleit- 

 NER. 176 pp. Published by R. Oldenbourg, Munich and Berlin, 

 1921. — The last edition of Groth 's ' ' Tabellarische Uebersicht der 

 Mineralien, nach ihren kristallographisch chemischen Beziehun- 

 gen geordnet" appeared in 1898. The notable increase in min- 

 eralogical knowledge that has come since that time has made a 

 new edition of this important book very desirable. It has been 

 published with the assistance of Dr. K. Mieleitner, the Curator of 

 the Mineralogical collection in Munich. The form of the book has 

 been changed in this edition but the manner of treatment has 

 remained essentially the same. A table for the determination of 

 the important minerals by means of their physical properties has 

 been added. w. e. f. 



9. Lehrhuch der Mineralogie; by Gustav Tschermak; 8th 

 edition by Friedrioh Becke. 751 pp., 977 figs, and 2 colored 

 pis. Published by Alfred Holder, Vienna and Leipzig, 1921. 

 — The first edition of this well known text book was published 

 in 1883, the sixth edition in 1905, the seventh by Dr. Becke in 

 1914, and after less than seven years this present edition in 1921. 

 The present book differs only in minor details from its immediate 

 predecessor and therefore needs no especial comment. The pub- 

 lication of such a book at the present time under the very great 

 difficulties that must prevail in Austria is especially noteworthy.

 Oscar S. Adams, Geodetic Computer. Special Publication No. 68, 

 U. S. Coast and Geodetic Survey. Pp. 163, 74 illustrations, 8 

 plates, 1921. — This publication is most welcome at this time 

 because of the recent increase in interest in, and the use of, maps 

 for many purposes. The dependence of the armies in the great 

 war upon accurate maps has led the map makers in and outside
