THE ANCIENT EGYPTIANS 



And their Influence on the Civilisation of Europe 



Illustrated 



The wonderful account of the Egyptians of the unrecorded 

 past which is revealed by the investigations of the anthropolo- 

 gist. The author traces to their sources the various streams of 

 alien immigrants which made their way into the Nile valley 

 6,000 years ago ; and is able to correlate his facts with the 

 great racial movements in the Mediterranean and the neigh- 

 bouring Continents. He shows also the influence the Egyptians 

 exercised in Africa, Asia, and especially in Europe in inaugu- 

 rating the higher civilisation particularly in bringing the 

 Stone Age to a close and introducing the use of metals.

THE REVOLUTIONS OF 

 CIVILISATION 



Ilhtstrated 



In the light of history so enormously extended in recent 

 years the author surveys the waxing and waning of civilisa- 

 tion as evidenced in sculpture, painting, literature, mechanics, 

 and wealth. In tracing the various forces at work in this 

 fluctuation he arrives at most significant conclusions, notably 

 in connection with race mixture and forms of government.

THE BIRTH OF WORLDS 

 AND SYSTEMS 



Illustrated 



A graphic statement of Prof. Bickerton's theory of "Con- 

 structive Impact" the formation of new stars from the collision 

 of dead suns or other celestial bodies. The detailed argument 

 certainly throws a flood of light on many astronomical problems, 

 while the theory as a whole with its conception of the cyclical 

 rejuvenescence of an immortal cosmos, is a generalisation of 

 great philosophical significance.
