Literary Nottces. XXV 
The Evolution of Man and his Mind.! 
This bulky volume, which contains much that is admirable, is de 
signed to be a popular exposition of the course of human evolution, 
particularly from the point of view of certain sociological defects of 
our present status. This makes a striking background for an exposé 
and arraignment of certain corrupt tendencies in our political and so- 
cial organization. ‘The literary style is colloquial and catchy and the 
book should do good in directing popular attention toward these abuses. 
As a whole, however, it is so ill-balanced and full of inaccuracies that 
it can hardly be commended as a helpful scientific contribution.

The Brain and Nerves of the Anamnia.? 
Professor JOHNSTON’s summary of recent progress in our knowl- 
edge of the central and peripheral nervous system of the Ichthyopsida 
is one of the notable papers of the year. The point of view from 
which he writes is so distinctively his own that his article is more than a 
mere abstract or critical review ; it is a positive contribution toward the 
solution of some of the major problems of comparative morphology. 
This point of view he has already presented in this Journal (March, 
1902), under the title, ‘An Attempt to Define the Primitive Functional 
Divisions of the Central Nervous System,” being essentially the corre- 
lation of central with peripheral differentiation of the nervous system. 
We venture the prediction that the next decade will see this principle 
worked out successfully in several fields at present open merely to the 
methods of descriptive anatomy. ‘lhe conclusions of students of 
nerve components as formulated at the present moment may or may 
not stand the test of time, but the esseutial aims and methods of work 
which they have introduced into comparative neurology will surely in 
the end yield results of permanent value. Professor JOHNSTON's 
Referat is therefore very timely. Gi Fi
