The present surface-inequalities are from 11 to 66 times the amount 

 producible by lateral thrust arising from contraction of the globe re- 

 garded as a cooling solid. The requisite contraction may be partly 

 due to escape of steam. W. H. D.

Lateral Pressure, upon the hypothesis of a liquid substratum.

Calculation of the form assumed under lateral compression by a 



flexible crust resting on a fluid. Unequal radial contraction will not 



account for the alternation in the same area of ocean and continent. 



Both the lateral-pressure and the liquid-substratum theories are borne 



out by geological evidence. W. H. D.
