appealed to if anybody ventured to doubt the possibility 

 of our being able to carry back our researches to the 

 creation of the present order of things." * Hutton 

 destroyed these characters, which were considered by 

 many as sacred, and declared that in the economy of the 

 world he could find " no traces of a beginning nor signs 

 of an end." And yet, as Lyell has shown, his principles 

 were only imperfectly carried through, for though he 

 maintained that " the strata which now compose our 

 continents have once been beneath the sea, and were 

 formed out of the waste of pre-existing continents," 2 he 

 imagined that when the decay of old continents had 

 furnished the material for new ones these were upheaved 

 by violent and paroxysmal convulsions. He therefore 

 required " alternate periods of general disturbance and 

 repose, and such he believed had been and would for 

 ever be the courses of nature." 3 A strange mixture of 

 the genetic and cyclical views of natural phenomena ! 

 Professor Huxley 4 has explained these seeming incon- 

 sistencies in the theory of Hutton, whom, together with 

 Sir Charles Lyell, he has described as having founded 

 the " uniformitarian " school of geology, by the influence 

 which the discoveries of physical astronomy, brought 

 out at that time by Laplace and his contemporaries, 

 had upon Hutton. Thus Hutton writes : " From seeing 

 revolutions of the planets, it is concluded that there 

 is a system by which they are intended to continue 

 those revolutions. But if the succession of worlds
