GEORGE J. ROMANES'S WORKS, 



JELLY-FISH, STAR-FISH, AND SEA-URCHINS. Being 

 a Research on Primitive Nervous Systems. 12mo. Cloth, $1.75. 



" Althoush I have throughout kept in view the requirements of a general 

 reader, I have also souaht to render the book of eervicu to tlie workint; pliysi- 

 oloi,'i8t, bv bringing together in one consecutive account all the more important 

 observations and results which have been yielded by this research.'"— J,'a;<r«c< 

 from Preface. 



" A profound research into the laws of primitive nervous systems conducted 

 by one of the ablest English investigators. Mr. Komanes set up a tent on the 

 beach and examined his beautiful pets lor six summcre in succession. Such 

 patient and loving work has borne its fruits in a monograph which leaves 

 nothinsrto be said about jelly-fleh, star-fish, and sea-urchins. Every one who 

 has stu'clied the lowest forms of life on the sea-shore admires these objects. But 

 few have any idea of the exquisite delicacy of their structure and their nice 

 adaptation to their place in nature. Mr. Romanes brings out the subtile beauties 

 of the rudimentary organisms, and shows the resemblances they bear to the 

 higher types of creation. His explanations are made more clear by a large 

 number of illustrations. While the book is well adapted for popular reading it 

 is of special value to working physiologists." — Neiv York Journal of Commerce. 



"A most admirable treatise on primitive nervous systems. The subject-matter 

 is full of original investigations and experiments upon the animals mentioned as 

 types of the lowest nervous developments."— 2J08to« Commercial Bulletin. 



" Mr. George J. Romanes has already established a reputation as an exact and 

 comprehensive naturalist, which his later work. ' Jelly-li'ish, Star-Fish, and Sea- 

 Urchius,' fully confirms. These marine animals are well known upon our coasts, 

 and always interest the on-lookers. In this volume (one of the 'International 

 Scientific Series ') we have the whole story of their formation, existence, nervous 

 system, etc., made most interesting by the simple and non-professional manner 

 of treating the subject. Illustrations aid the text, and the professional student, 

 the naturalist, all lovers of the rocks, woods, and shore, as well as the general 

 reader, will find instruction as well as delight in the narrative."— i^o^to/i Com-

ANIMAL INTELLIGENCE. 12mo. Cloth, $1.75. 



"A collection of facts which, though it may merely amuse the unscientific 

 reader, will be a real boon to the student of comparative psychology, for this is 

 the first attempt to present systematically the well-assured results of observation 

 on the mental life of animals." — Saturday Remew. 



MENTAL EVOLUTION IN ANIMALS. With a Posthumous 

 Essay on Instinct, by Charles Darwin. 12mo. Cloth, $2.00. 



" Mr. Romanes has followed np his careful enumeration of the facts of ' Ani- 

 mal 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 

 ot industry in collecting facts and caution in co-ordinating them by theory as the 

 lormer."— 27te Athenceum.
