for the notes on the distribution of species are too general or too slight 
to be of much service. 
The book is brightly written and is assured, and deservedly so, of 
a wide circulation. 
SHOOTING TRIPS IN EUROPE AND ALGERIA. By Hugh P. Highton. 
London: H. F. & G. Witherby. Price 16s. net. 
As stated in the sub-title, this is a record of sport in the Alps, 
Pyrenees, Norway, Sweden, Corsica, and Algeria. It is an interesting 
and readable volume, and from a perusal of its pages one gains a pretty 
accurate idea of the varied experiences of the sportsman in his quest for 
game. The selection of guides (more or less of a speculation !), the 
preparation of his kit, and the attempts to discover the best ground for 
action, are all graphically described, while to the naturalist who has never 
seen the chamois, the mouflon, and the Barbary sheep in their native 
haunts, it is fascinating to read of the various methods adopted by the 
~ hunter in the tracking, stalking, and outwitting of his prey, and to learn 
from a sportsman of experience what is essential to success. The 
author is alive, too, to the charm of natural scenery, which is described 
in a vigorous style, while the sundry touches of humour and the excellence 
of the illustrations go to make up a fascinating volume, which is at the 
same time an excellent guide to the art of hunting in regions fairly 
accessible to the British tourist. 
Sympiosis: A Socio-PHySIOLOGICAL STUDY OF EvoLuTIoN. By 
H. Reinheimer. London: Headley Brothers, 1920. Price

Convinced that much of the significance of the living world is lost if 
the evolution of life be not viewed as a moral progress, the author ina 
reasoned and learned treatise develops a moral philosophy of organisms. 
In this, each organism comes to be known as “good” or “bad,” 
progressive or decadent, for “it is the conscientious organism alone 
which, strictly pursuing a legitimate pathway of life, and refusing to 
dally with evil, in the end achieves successful survival.” To the author 
the only legitimate pathway lies along the line of systematic biological 
co-operation or Symbiosis, while the predatory or parasitic mode of life 
is evil and invariably leads to degeneracy and extinction. Rightly, 
great stress is laid upon the value of helpful inter-relationships and the 
close correlation of organism and environment in the evolution of 
organic nature, but no good purpose is served by so widening the 
accepted meanings of terms that “‘conscientiousness” and “ morality” 
become attributes of plants and animals which lack self-consciousness, 
or co-operation comes to express the relationship between a cow and 
the grass it eats.
