THE POPULAR SCIENCE MONTHLY. 



the other to the evolution of mind in man. 

 The volume now before us, the second pub- 

 lished, is an exposition of comparative psy- 

 chology on the basis of his first volume, 

 and designed to exhibit mental evolution in 

 the lower grades of the animal kingdom. 

 The psychology of man is therefore ex- 

 pressly excluded from the volume before us, 

 and the author offers, as one reason for this 

 exclusion, that human psychology raises a 

 class of questions with which he has no 

 concern in deahng with comparative psy- 

 chology. Prominent among these he as- 

 sumes is the fundamental question whether, 

 indeed, the principle of evolution is to be 

 applied to the psychology of man. Although 

 unquahfiedly assumed in his first volume 

 and in the present as fundamentally true, 

 and the sole key of interpretation in the 

 lower sphere of mind, yet the author hesi- 

 tates in its application to human psychology 

 because Mr. Wallace differs with Mr. Dar- 

 win upon this subject. The issue between 

 these great naturalists is, however, to be 

 met and fully considered in the final volume. 



Mr. Romanes explains in his introduc- 

 tion that, in treating of " Mental Evolution 

 in Animals," he dismisses a class of in- 

 quiries hitherto involved in psychology, but 

 which pertain rather to the philosophy than 

 to the science of the subject. He deals with 

 the science of psj-chology as distinguished 

 from any theory of knowledge, limiting 

 himself to the study of mind as an object, 

 and of mental modifications simply as phe- 

 nomena. 



We can only briefly indicate the course 

 of inquiry in the volume before us. Begin- 

 ning with a search in the first chapter for 

 " The Criterion of Mind," he then passes on 

 in successive chapters to " The Structure 

 and Functions of Nerve - Tissue," " The 

 Physical Basis of Mind," " The Root Prin- 

 ciples of Mind," " Consciousness," " Sensa- 

 tion," " Pleasures and Pains," " Percep- 

 tion," " Imagination," " Instinct," and this 

 latter subject, which is the most prominent 

 in the discussion, runs on from chapter elev- 

 enth to chapter eighteenth. " Reason " and 

 " Animal Emotions " then come in for some 

 consideration, and the volume closes with 

 an appendix of thirty pages, consisting of a 

 posthumous essay on "Instinct," by Mr. 

 Charles Darwin, which was written for his 



book on "Natural Selection," but not in- 

 cluded in it. Mr. Darwin left his psycho- 

 logical manuscripts to Mr. Romanes, to be 

 printed or not as he thought fit, and he has 

 included the essay on " Instinct " in his 

 present disquisition on " Mental Evolution 

 in Animals." It has been objected that 

 Mr. Darwin was no psychologist ; that he 

 wrote on the subject long ago, and did not 

 himself see fit to print what he had written ; 

 and that, on the whole, it would have been 

 better for Mr. Darwin's reputation, and just 

 as well for the world, if this old essay had 

 not now been issued. But we think that 

 Mr. Romanes -was right in printing it. It 

 can not seriously injure Mr. Darwin's repu- 

 tation ; and, if it does not help other people 

 much, it will undoubtedly have interest as 

 a record of the state of Mr. Darwin's mind 

 upon that subject. If not a contribution to 

 " Mental Evolution in Animals," it may pos- 

 sibly help to interpret the mental evolution 

 of man. 



The Franco- American Cookert-Book ; or. 

 How to live well and wisely Every Day in 

 the Year : containing over Two Thou- 

 sand Recipes. By P'klix J. Deliee, 

 Caterer of the New York Club, ex Chef 

 of the Union and JIanhattan Clubs. 

 New York : G. P. Putnam's Sons. Pp.

This considerable volume claims to fill a 

 void in our culinary literature. It presents 

 three hundred and sixty-five different dinner- 

 bills of fare, one for each day in the year, 

 made up with reference to the resources of 

 the changing seasons, and, following each, 

 concise instructions are given how to prepare 

 the various dishes designated. Such a work 

 can not fail to be of service, not only to pri- 

 vate families, but to clubs, restaurants, and 

 hotels, and it could hardly have a better pass- 

 port to general use in this country than the 

 name of the experienced chef which appears 

 upon its title-page. Each bill of fare differs 

 almost entirely from the others, while at the 

 same time the selection is made with strict 

 regard to the products of the season and the 

 supplies afforded by markets in American 

 cities. Each is calculated for eight per- 

 sons, though the cook or housekeeper may 

 increase or reduce it at will by observing 

 the proportions with care. 



It is claimed that every dish described
