in the lowlands have been preserved from denudation ; accord- 

 ingly " the Palaeozoic seas extended very widely, if not completely, 

 over the Laurentian upland southeast and east of Hudson bay." 

 The paper is a valuable contribution toward a better understand- 

 ing of the paleogeography of Ordovician, Silurian, and Devonian 

 times. c. s. 



10. Geology of Franklin County ; by A. M. Mtller. Ky. 

 Geol. Surv., 4th series, vol. 2, 1914, pp. 7-87. — This excellent 

 report maps and describes in great detail the various Ordovician 

 formations of Franklin County, central Kentucky. The Mohawk- 

 ian series is divided into nine members, and the Cincinnatian into 

 five. Commonly the Eden is regarded as at the base of the Cin- 

 cinnatian series, but in this report the Cynthiana is the founda- 

 tion, a formation unknown in the standard section of New York. 

 The soils of the county are described in an additional paper 

 (pages 89-144) by S. C. Jones. c. s. 



11. Revision of the Tertiary Mollusca of JVew Zealand; by 

 Henry Suter. New Zealand Geol. Surv., Palpeontological Bull. 

 No. 2 (Part I), 1914, pp. 64, 17 pis.; No. 3 (Part II), 1915, pp. 

 69, 9 pis. — In these publications all of the new species defined 

 many years ago by Captain F. W. Hutton and others are revised 

 in the light of modern knowledge of the Recent Mollusca. They 

 comprise a first step toward a revision of the Tertiary Mollusca 

 of New Zealand. c. s. 



12. Third Appendix to the Sixth Edition of Dana 's System of 

 Mineralogy • by William E. Ford. Completing the work to 

 1915. Pp." xiii, 87. New York, 1915 (John Wiley & Sons). — 

 This third appendix to Dana's System has been prepared by 

 Prof. W. E. Ford, to whom the science owes also the completion 

 of Appendix II, seven years ago. Notwithstanding the fact that 

 mineralogy is sometimes regarded as the most nearly complete of 

 all the sciences, descriptions of new occurrences still go on actively 

 and no fewer than one hundred and eighty new names have been 

 added between 1908 and 1915 ; of these about one-third are 

 regarded by Professor Ford as probably well established species. 

 This Appendix follows the lines laid down in its predecessors, but 

 special attention is given to the literature of X-rays and crystal 

 structure.
