4 maps (topography and geology) in separate case. These maps 

 cover respectively Barbour county, and Upshur county and the 

 coal area of Randolph west from Big Laurel and Rich Mountains. 

 The whole region is underlain by the Coal Measures in which are 

 several valuable beds, all of which are described, analyzed, and 

 their areas mapped in this report. Price (including case of 

 maps, delivery charges prepaid), $3.00. Extra copies of geologic 

 map of Upshur and Western Randolph, $1.00; of Barbour, 75 

 cents; of topographic map of Upshur and Western Randolph, 

 75 cents; of Barbour,. 50 cents.

4. The Evolution of the Earth and, its Inhabitants; by 

 Joseph Barrell, Charles Schuchert, L. L. Woodruff, R. S. 

 Lull, and Ellsworth Huntington. Pp. 208, 4 pis., 38 text 

 figs. Yale University Press, 1918 ($2.50). — During the winter 

 of 1916-1917, the Yale Chapter of the honorary scientific society 

 of the Sigma Xi, under the presidency of Professor Richard S. 

 Lull, presented a series of popular lectures on the geological and 

 biological evidences for the evolution of our planet and its life. 

 These are now published in book form. The lectures are : 1, The 

 origin of the earth, by Professor Barrell; 2, The earth's chang- 

 ing surface and climate, by Professor Schuchert ; 3, The origin 

 of life, by Professor Woodruff ; 4, The pulse of life, by Professor 

 Lull ; and 5, Climate and civilization, by Doctor Huntington. 

 They ought to be of wide interest in scientific circles. The book- 

 making is of the best.

 of the American fossil Equidse from the Oligocene to the Pliocene 

 inclusive. It consists of the usual preface, a summary of the 

 head and limb ratios and indices used in the work, and an expo- 

 sition of tooth morphology. Then follows a description of the 

 chief geologic horizons, formations, and levels which contain 

 equine remains, together with the principal geographical local- 

 ities, all of which is summarized on page 35. 



The systemic portion of the work is the most extensive and 

 embraces every known species, reference to the original descrip-
