[ Abstract. ] 
According to Mr. Mallet’s theory, as detailed in the two papers 
named above, the amount of heat lost from the initial temperature 
of the earth will represent in units of energy the force of its con- 
traction, which he assumed will be active, especially in surface 
phenomena. To the force of contraction developed by cooling Mr. 
Mallet attributes the inclination, upheaval, crumpling, and dislo- 
cation of all strata, past or present, together with all volcanic 
phenomena. 
The calculations for the amount of energy upon which he most
