DARWINISM STATED BY DARWIN HIMSELF: Char- 

 acteristic Passages from the Writiugs of Charles Darwin. Selected 

 and arranged by Professor Nathan Sheppabd. 12mo, cloth, 360 

 pages, $1.50. 

 "A compact and clear statement of the doctrinee collectively known aB Dar- 

 winism. By consulting this single volume it is now possible to know exactly what 

 Darwin taught without sifting the contents of a dozen books. M r. Nathan Shep- 

 para has edited the work witb good judgment."— iVew Torle Journal of Commerce. 

 " Mr. Sheppard must be credited with exemplifying the spirit of impartial 

 truth-seeking which inspired Darwin himself. From these condensed results of 

 the hard labor of selection, excision, and arrangement applied to more than a 

 dozen volumes, it is impossible to draw any interence respecting the philosophi- 

 cal opinions of the compiler. With the exception of a brief preface there is not a 

 word of comment, nor is there the faintest indication of an attempt to infuse into 

 Darwin's text a meaning not patent there, by unwarranted sub-titles or head- 

 lines, by shrewd omission, unfair emphasis, or artful collocation. Mr. Sheppard 

 has nowhere swerved from his purpose of showing in a clear, connected, and very 

 compendious form, not what Darwin may have meant or has been charged with 

 meaning, but what lie actually said." — The Sun. 



MENTAL EVOLUTION IN ANIMALS. By Gkokge J. Eomakes, 

 author of "Animal Intelligence." With a Posthumous Eseay on 

 Instinct, by Charles Dakwin. 12mo, cloth, $2.00. 



" Mr. Romanes has followed up his careful enumeration of the facte of 'Animal 

 Intelligence,' contributed to the 'International Scientific Series,' with a work 

 dealing with the successive stages at which the various mental phenomena appear 

 in the scale of lite. The present installment displays the same evidence of indus- 

 try in collecting facts and caution in co-ordinating them by theory as the former."
