84 Mr HOPKINS, ON RESEARCHES IN PHYSICAL GEOLOGY. 



nearly to the surface, in comparison with those which would do so in 

 cases where these fissures should originate at a much smaller depth. 

 The complete fissures would consequently be distant from each other 

 and very large, and all the phenomena of elevation resulting from them 

 might be expected to be of proportionate magnitude. I liave no inten- 

 tion, however, of insisting on this extended application of our theory, 

 but merely to indicate its possible extension (should established geo- 

 logical facts appear hereafter to require it) to account for phenomena 

 on a much larger scale than those to which I have considered it essential 

 to refer in the preceding investigations.
