THE TWIN RECORDS OF CREATION; or, Geology and 



Genesis: their Perfect Harmony and Wonderful Concord. By Geokge W. 



Victor le Vaux. Numerous Illustrations. Fcap. 8vo, 5s. cloth. 



"A valuable contribiUion to the evidences of revelation, and disposes very conclusively of the 

 .ir^unients of those who would set God's AVorks against God's Word. No real difficulty is shirked, 

 anil no sophistry is left unexposed." — The Kocf:. 



" The remarkable peculiarity of this author is that he combines an unbounded admiration of 

 science with an unbounded admiration of the Written Record. The iwo impulses are balanced to a 

 nicety ; and the consequence is that difficulties which to minds less evenly poised would be seiiuus 

 find inunediatc solutions of the happiest kinds." — London Rcvieiv,
