MATERIAL UNIVERSE. 79 



The waters continued to cool ; all the 

 changes having taken place beneath them of 

 which the elements of matter diffused therein 

 were susceptible. The design of the Creator 

 had been accomplished, in preparing the earth 

 for a habitation, and in producing a race fitted 

 to inhabit it. The waters were no longer of a 

 uniform temperature. The central heat not act- 

 ing with sufficient energy, at the poles of the 

 earth, to maintain an equable heat over the 

 whole surface, a current was formed, and the 

 winds were set in motion, whereby the air was 

 impelled from a more dense to a rarer medium. 

 But so gradual was the change, (as had been all 

 changes since the formation of the fluid globe,) 

 that the direction of the vapor, arising from the 

 earth, was, at first, scarcely swayed from the 

 perpendicular motion which had hitherto gov- 

 erned it. But, as the temperature of the waters 

 became farther reduced, the winds increased in
