Weis, F., Live't og dets Love. En Fremstilling af den 

 almindelige Biologie. [Life and its laws, a sketch of 

 general Biology]. (Kjöbenhavn 1911. (Gad.) 563 pp. 183 lig.)

 matter are named; yet an interesting historical account is given, 

 describing the views of the ages upon living nature and accom-

 present times are dealt with, they are arranged under two headings, 

 viz. 1) General conditions of life. 2) Fundamental manifestations 

 of life. 



Under "General conditions" the following items are found. 

 Firstly, the substantial base for life is mentioned, the essential 

 features of living structures being described and figured; and also 

 here we find a brief historical account on cell-investigation. The 

 individual in its relations to other individuals is dealt with, and the
