 OF GASES AND THE ABSOLUTE ZERO OF TEMPERATURE FUSION AND 

 SOLIDIFICATION THE PROBLEMS OF SOLUTION THE CONDUCTION OF 

 ELECTRICITY THROUGH GASES RADIO-ACTIVITY ATOMS AND ^TH^R 

 ASTRO-PHYSICS. 



' Mr. Whetham's book will be welcomed. Its appearance is highly oppor- 

 tune. There probably never was a time when a clear and compendious 

 account of contemporary physical research was more needed. . . . He has 

 performed a difficult task with conspicuous success. His exposition is as clear 

 and simple as the nature of the subject permits, and his language is felicitous.'
