GEORGE J. ROMANES'S WORKS. 



JEIiLY-FlSH, STAR-FISH, AND SEA-URCHINS. Being 

 a Research on Primitive Nervous Systems. 12mo. Cloth, $1.76. 



"Althoogli I have throughont kept in view the requirements of a general 

 reader, I have alsu Boueht to render the book of service to the workiug physi- 

 ologist, by briuging together in one consecutive account all the more important 

 observations and results which have been yielded by this re8earch."^jE^ir(Zci 

 from Preface. 



*' A profound research into the laws of primitive nervous systems conducted, 

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

 beach and examined his beautiful pets tor six summere in euccession. Such 

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

 nothing to be said about jelly-fish, star-fish, and sea-urchins. Every one who 

 has studied 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. Komanes brings out the subtile beauties 

 of the rudimentary organisms, and shows the rescmDlances 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."— i\^e«; York Journal of Commerce. 



''A most admirable treatise on primitive nervous systems. The enbject-matter 

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

 types of the lowest nervous developments."— Boston Commercial Bulletin. 



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

 comprehensive naturalist, which his later work, ' Jelly-Eish, Star-Fish, and Sea- 

 Urchins,' 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«tow Com- 

 nwnwealth. 



ANIMAL INTELLIGENCE. 12mo. Cloth, %\.1^. 



"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 or animals." — Saturday Review. 



MENTAL EVOLUTION IN ANIMALS. 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 ' 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 

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

 former,"— 2^ Athenceum.
