GEORGE J. ROMANES’S WORKS. 
JELLY-FISH, STAR-FISH, AND SEA-URCHINS. Being 
a Research on Primitive Nervous Systems. 12mo. Cloth, $1.75. 
“ Although I have throughout kept in view the requirements of a general 
reader, I have alsu sought to render the book of service to the working physi- 
ologist, by bringing together in one consecutive account all the more important 
observations and results which have been yielded by this reeearch.”—£atract 
trom 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 beantiful pets tor six summers in succession. Such 
patient and loving work has borne 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. 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 
uumber of illustrations. While the book is well adapted for popular reading it 
is of special value to working physiologists.” —New York Journal of Commerce. 
‘* A most admirable treatise on primitive nervous systems. The subject-matter 
is full of praia 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 Jater work, ‘Jelly-Fish, 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. LJustrations aid the text, and the professional student. 
the naturalist, all lovers of the rocks, woods, aud shore, as well as the genera 
reader, ae find instruction as well as delight in the narrative.”— Boston Com- 
monwealth. 
ANIMAL INTELLIGENCE. 12mo. Cloth, $1.75. 
‘°A collection of facta 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 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.”’— The Atheneum.
