MODERN SCIENCE SERIES. 



Edited by Sir John Lubbock, Bart.,F.R. S. 



The works to be comprised in the " Modern Science Series " are primarily not for 

 the student, nor for the young, but for the educated layman who needs to know the 

 present state and result of scientific invesdgation, and who has neither time nor inclina- 

 tion to become a specialist on the subject which arouses his interest. Each book will 

 be complete in itself, and, while thoroughly scientific in treatment, its subject will, as 

 far as possible, be presented in language divested of needless technicalities. Illustra- 

 tions will be given wherever needed by the text. The following are the volumes thus 

 far issued. Others are in preparation.

 lished, but he thinks that he can add something to the amount of useful information
