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

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



" Althon<::h I have throui^hont kept in view the requirements of a general 

 reader, I nave also eouiiht to render the book of service to the workiiiir phyti- 

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

 observ.itions and results which have been yielded by this research." — Extract 

 from P> eface. 



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

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

 beach and examined his beautiful pets lor six summers in succession, t-uch 

 patient and loving work has borne its fruits in a mcsnograph winch leaves 

 nothing to be said about jslly-Qsh, t tar-fish, and sea-urchins. Every one who 

 has stuliied the lowest forms of lit\; 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 suotile beauties 

 of t.ie ruaimenrary organisms, and shows tiie resi-mblances tiiey bear to ttie 

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

 number of illustrations. While the book is well adapred lor ; opuiar reading it 

 is of special value to working physiologists. "'—iV'e?^ lork Journal oj Commerce. 



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

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

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



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

 comprehensive naturalist, which ids later work. ' Jelly-i'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 'luternational 

 Scientific series ') we have the whole story of their toimation, existence, nervous 

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

 of treating the subject. Ihustrations aid the text, and the proiessional student, 

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

 reader, will find instruction as well as delight in the narrative."— £o6fon Com- 

 monwealth. 



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 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 Inteliigence,' contributed to the ' International Scientific Series,' witli a 

 work dealini,' with ilie successive stages at which the vaiions mental phenomena 

 app iar in the scale of life. The present installment displays the same evidence 

 of industry m coUectini; facts and caution in co-ordinating them by theory as the 

 lormer."— TVie Athenceum.
