JELLY-FISH, 8TAR.FISH, AND S£A.URCHINS. Being 

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



*^ AlthoDfrli I have thronghoat kept in view the reqairements of a general 

 reader, I have alBo som^ht to render the book of Bervice to the working pbyei- 

 ologiBt, by hriDging together in one conBecutire account all the more important 

 observutionB and resnlta which have been yielded by this research.''— ^^roc^ 

 from Preface, 



" A profound research into the laws of primitive nervons syBteme conducted 

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

 beach and examined his beantifol pets tor six summere in eucceBBion. Such 

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

 nothing to be eaid about jelly-flshf etar-flsh, and sea-nrchins. Every one who 

 has studied the lowest forma of life on the sea-shore admires these objects. But 

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

 adaptaLioD to their place io nature. Mr. Komanes brings out the subtile beauties 

 of tlie rudimentary organisms, and shows the rescmblaDces they bear to the 

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

 number of illustrations. While the book ie well adapted for popular reading It 

 is of special value to working physiologists."— iVew York Jourruil qf Commerce. 



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

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

 types of the lowest nervous developmeats."- ^M^on Commercial Bulletin. 



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

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

 UrcnioB,' folly confirms. These marine animals are well known upon our coasts, 

 and always interest the on-lookers. tn this volume (one of the ' iDternational 

 Scientific Series *) we have the whole story of their formation, e^Btence, nervous 

 syBtem, etc., made moBt interesting by the simple and non-professional manner 

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

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

 reader, will find instrnction as well as delight in the narrative."— JSMton Com^ 



ANIMAL INTELLIGENCE. 12mo. Cloth, $1.75. 



*^A collection of facts which, though It may merely amuse the unBCientiflc 

 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 oi9xAaa\^J'^~Saturday Seview. 



MENTAL ETOLUTION IN ANIMALS. With a Posthumous 

 Essay on Instinct, by Ghables Dabwin. 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 stagee 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." — I%e Athemeum.
