GEORGE J. ROMANES’S WORKS. 
MENTAL EVOLUTION IN MAN: Origin of Human Faculty. 
One vol., 8vo. Cloth, $3.00. 
This work, which follows “Mental Evolution in Animals,” by the same au» 
thor, considers the probable mode of genesis of the human mind from the mind 
of lower animals, and attempts to show that there is no distinction of kind be- 
tween man and brute, but, on the contrary, that such distinctions as do exist all 
admit of being explained, with respect to their evolution, by adequate psycho- 
logical analysis. 
“The vast array of facts, and the sober and solid method of argument em- 
ployed by Mr. Romanes, will prove, we think, a great gift to knowledge.”— 
Saturday Review. 
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 also 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 research,”—Aatract 
Srom Preface. 
‘A profound research into the laws of primitive nervons systems conducted 
by one of the ablest English investigators. Mr. Romanes set up a tent on the 
beach and examined his beautiful pets for six summers in succession, Such 
patient and loving work has borne its fruits in a monozraph which leaves noth- 
ing to be said about jelly-fish, atur-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 adapta- 
tion to their place in nature. Mr. Romanes brings out the subtile beauties of 
the rudimentary orzanisms, and showe the resemblances they bear to the higher 
types of creation. His explanations are made more clear by a large number of 
illustrations.”"—Wew York Journal of Commerce. 
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 observa’ 
tion on the mental life of animals.”—Saturday Review. 
MENTAL EVOLUTION IN ANIMALS. With a Posthumous 
Essay on Instinct, by Caartes 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 piece installment displays the eime evidence 
of industry in collecting facts and caution in co-ordinating them bj theory as the 
former.”— The A um.
