D. APPLETON & CO.'S PUBLICATIONS. 



DARWINIS3I STATED BY DARWIN HIMSELF: Char- 

 acteristic Passages from the Writings of Charles Darwin. Selected 

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

 pages, $1.50. 



" A compact and clear etateraent of the doctrines collectively known as Dar- 

 winipm. By consulting this single volume it is now poesible to know exactly what 

 Darwin taught without sifting the contents of a dozen books. Mr. Nathan'Shep* 

 para has edited the work with good judgment."— iVew Yorh 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 inference 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 test a meaning not patent there, by unwarranted sub-titles or head- 

 Klines, 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 he actually said." — The Sun. 



MENTAL EVOLUTION IN ANIMALS. By George J. Romanes, 

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

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



" Mr. Romanes has followed up his careful enumeration of the facts 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 life. The present installment displays the same evidence of indus- 

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

 — The Athenaeum. 



"■ The author confines himself to the psychology of the subject. Not only are 

 his own views Darwinian, but he has incorporated in his work considerable cita- 

 tions from Darwin's unpublished manuscripts, and he has appended a posthu- 

 mous essay on Instinct by Mr. Darwin."— i?os^on Journal. 



"A curious but richly suggestive volume."— iVisw York Serald. 



PRACTICAL ESSAYS. By Alexander Bain, LL. D., author of 

 " Mind and Body," " Education as a Science," etc. ] 2mo, cloth, $1.50. 

 "The present volume is in'part a reprint of articles contributed to reviews. 

 The principal bond of union among them is their practical character. . . . That 

 there is a certain amount of novelty in the various suggestions here embodied, will 

 be admitted on the most cursory perusal."— i^rom the Preface. 



THE ESSENTIALS OF ANATOMY, PHYSIOLOGY, AND 

 HYGIENE. By Roger S. Tracy, M. D., Health Inspector of the 

 New York Board of Health ; author of " Hand-Book of Sanitary In- 

 formation for Householders," etc. (Forming a volume of Appletons' 

 Science Text-Books.) 12mo, cloth, $1.25. 

 "Dr. Tracy states in his preface that his aim has been 'to compress within 

 the narrowest space such a clear and intelligible account of the structnres, activi- 

 ties, and care of the human system as is essential for the purposes of general 

 education.' And he has so far succeeded as to make his manual one of the most 

 popularly interesting and useful text-books of its kind. . . . The book is excel- 

 lently arranged, the illustrations are admirable."— Boston Daily Advertiser.
