Biological Essays by 
Jacques Loeb 
Head of the Depariment of Experimental Biology 
_ Rockefeller Institute for Medical Research 
“HE achievements of Professor Jacques 
Loeb in the field of experimental biology 
have made him so widely known as to 
insure any book of his a large and interested 
circle of readers. 
Tn his latest work, The Mechanistic Concep- 
tion of Life, Professor Loeb presents many 
of the current problems in biology on which 
he has been engaged in recent years. These 
may be characterized in a general way as 
an attempt to analyze life from a purely 
physicochemical standpoint.
