216 THE NEW KNOWLEDGE. 



This diagram informs us that in the running down of 

 temperature from the 30,000 degrees Centigrade, which is 

 estimated as the temperature of the hottest stars, to the 

 average temperature of the earth, that the position of or- 

 ganic evolution is a mere point in the scale somewhere be- 

 tween the temperature at which water boils and ice melts, 

 and yet we measure that point by many millions of years.
