10. Report of the Vermont State Geologist for 1909-1910; 

 by George H. Peukixs. Pp. xii, 361, pis. 71. 1910 [Jan. 1911]. 

 — The volume opens with an account of the History and Condi- 

 tions of the State Cabinet, by the State Geologist. The granites 

 of the state are described by T. Nelson Dale, in an article which 

 is practically a reprint of a bulletin of the U. S. Geological Pur- 

 vey. C. II. Hitchcock has a chapter on the Surfacial Geology of 

 the Champlain Basin and Percy E. Raymond brings together all 

 that is known about the trilobites of the Chazy formation in 

 Vermont. The latter comprise 36 species, all of which are illus- 

 trated. Professor Perkins describes the geology of the Burling- 

 ton Quadrangle and Professor Seely has a preliminary report on 

 the Geology of Addison County. Asbestos in Vermont is treated 

 by C. H. Richardson and the mineral resources by the State 

 Geologist. c. s. 



11. A Contribution to the Geologic History of the Floridian 

 .Plateau ; by Thomas Wayland Vaughan. Carnegie Institution 

 of Washington, Publiration 133, pp. 99-185, 15 pis., 6 text figs. 

 !910. — This well written and very interesting work should be 

 studied by all stratigraphers and geologists because here we have 

 worked out with care the present conditions of deposition and 

 geologic work now going on in the Floridian region as a basis 

 toward a proper interpretation of the Tertiary history of the 

 peninsula. The author first describes the topography of the 

 Floridian Plateau and then goes into considerable detail in regard 

 to the marine bottom deposits forming in the bays and sounds 

 behind the keys. Limestones are here being made by precipita- 

 tion from the sea water as amorphous calcium carbonate and are 

 apparently not of detrital origin. It is a soft ooze into which a 

 rod can be forced down ten feet or more ; in fact, the depth of 

 this soft material has not been determined. 



Vaughan then discusses the transporting agents (currents and 

 winds) of the Florida coast and their effects. The smaller half 

 of the work treats of the geologic history of the Floridian Pla- 

 teau. The history is worked out in some detail and the book is 

 abundantly illustrated by maps, one of which presents the geolo- 

 gic formations of the state. There are also many photogravures 

 of vegetation, sea shores, and geological deposits. c. s. 



12. Recent Discoveries Bearing on the Antiquity of Man in 

 Europe; by George Grant MacCurdy. Smithsonian Report 

 for 1909, pages 531-583, pis. 1-18. 1910. — The author brings 

 together here the accounts of the many wonderful discoveries 

 that have been made in the past ten years bearing upon the
