ited, — and that Santa Rosa ridge has the topographic character- 

 istics of a faulted block. The structure of the valley floor has 

 been determined and a study made of the origin and character 

 of the delta silts, consolidated Tertiary beds, sand dunes and 

 saline deposits. h. e. g. 



6. Die Alpen im JElszeit alter ; von Dr. Albreoht Penck 

 und Dr. Eduard Bruckner. In three vols., 1 1 T6 pp., 37 plates, 

 136 figures, 19 maps. Leipzig (Tauchnitz). — With the publication 

 of parts 9, 10, and 11, including the continuation of the study of 

 the glaciation of the southern and eastern Alps, this great work is 

 brought to its close. The concluding parts on Glacial Physiog- 

 raphy (pp. 1141-1152) and the chronology of the Ice Age (pp. 

 1153-1156) by Professor Penck present the prominent results of 

 glaciation in a clear manner and make it possible to compare the 

 glacial history of the Alps with that of other regions. 



The first instalment of this work was issued in December, 1901, 

 and the concluding chapter bears the date of December, 1908. 

 While much of the field work on which it is based had been 

 previously done, new observations and development of new 

 theories have made it necessary to enlarge the original scope and 

 to delay, accordingly, the final completion of the work. As it 

 stands, it is probably the most important work on glacial geology 

 ever issued, not only for the detailed description and explanation 

 of this classic region for glacial study, but also for its contribu- 

 tions to the general science of glaciology. h. e. g.

 — The author is in the main reactionary and out of harmony with 

 the methods and explanation usually given as to the causes for 

 organic change. Lamarck and Goethe are his standard-bearers. 

 The book is dedicated to Lamarck and from his work he selects 

 as his text "All living families subsist in spite of their variation." 

 The historical method or the appearance of organisms in sequence 

 of time plus Steinmann are his main principles. Darwin's book, 

 he states, should not have been called " Origin of Species " but 

 " Changeability of Organisms." Through paleontology alone is 

 it possible to understand the changes that have taken place in the 

 organic world. To ask the object of an organ or an organization
