THE POPULAR SCIENCE MONTHLY. 



ity of that varied, methodic, and per- 

 sistent exercise of the mental faculties 

 which gives them their soundest and 

 most symmetrical discipline. Modern 

 studies have become the rivals of an- 

 cient studies, and the discipline of sci- 

 ence the rival of classical discipline. 

 The discipline of science is superior to 

 lingual and literary discipline because 

 it involves all the mental processes, 

 because it takes eflfect upon the reali- 

 ties of experience, because it is a dis- 

 cipline in the pursuit of truth, because 

 it is a preparation for practical life- 

 work, because it uses the most perfect- 

 ed knowledge as its means of culture, 

 and because it brings the mind into 

 intimate and intelligent relation with 

 the system of natural things, which it 

 is the first interest as it is also the 

 highest pleasure of man to understand. 



A CORRECTION. 



An article contributed to the " North 

 American Review " for August, by Mr. 

 George J. Romanes, an English author, 

 opens with the following passage : " A 

 few months ago I published a work en- 

 titled 'Mental Evolution in Animals,' 

 in which I attempted to trace as care- 

 fully and thoroughly as I was able the 

 principles which have probably been 

 concerned in the development of mind 

 among the lower animals. This work, 

 I believe, has already been reprinted in 

 America ; and seeing that, under the 

 existing state of matters with reference 

 to copyright, an author on this side of 

 the Atlantic is precluded from securing 

 any pecuniary interest in the sale of his 

 work upon the other side, I am free to 

 allude to this book as constituting the 

 basis of the present paper." 



We read this statement with some 

 surprise. Had Mr. Romanes said, " The 

 American people deny my ownership 

 of the book that I have made and 

 which they reprint, and I therefore hold 

 myself absolved from recognizing any- 

 body's ownership of the reprint," his 

 position would be intelligible. But, 



when he says he proposes to make use 

 of its contents as he pleases because he 

 " is precluded from securing any pecun- 

 iary interest in the sale of his work " in 

 this country, his statement creates a 

 false impression, and one which we are 

 personally concerned to correct. Mr. 

 Romanes contributed " Animal Intelli- 

 gence " to the " International Scientific 

 Series," a project which was undertaken 

 expressly in the pecuniary interest of 

 scientific authors ; and on all sales of 

 this book the stipulated royalty is placed 

 to his credit, to be drawn by his English 

 publishers. It was intended, as we un- 

 derstand, at first to include the ''Men- 

 tal Evolution in Animals " in the "Se- 

 ries " also ; but, although this was not 

 done, it is to be paid for under arrange- 

 ment by the American publishers at the 

 same rate. When the profits are earned 

 by the sale of the volume, Mr. Romanes 

 will be entitled to them by contract, 

 and he thus stands upon the same prac- 

 tical footing as an American author. 



LITERARY NOTICES. 



Outlines op Psychology, with Special 

 Reference to the Theory of Educa- 

 tion. By James Sully, author of 

 " Illusions," etc. New York : D. Apple- 

 ton & Co. Pp. 711. Price, $3. 

 Mr. Sully has brought to the prepara- 

 tion of this comprehensive work unusual 

 accomplishments for the task. He is well 

 known as an indefatigable student of men- 

 tal science, and his numerous contributions 

 to the leading English periodicals, on ad- 

 vanced pyschological questions, give liim a 

 high rank both as an original inquirer and 

 an attractive and successful writer upon 

 these subjects. He is the author of several 

 systematic works, one of which, on " Illu- 

 sions," prepared for the " International Sci- 

 entific Series," has been republished in this 

 country. Mr. Sully is thoroughly familiar 

 with the results and methods of the modern 

 English school of psychological thought, and 

 he has also pursued his studies in Germany 

 under the ablest masters, so that he is well 

 equipped for dealing with the subject in 

 the light of the most advanced views. It
