distinctly both trends, and:they are so mentioned without allud- 
ing to any general law, by Darwin.t Beyond the American con- 
tinent, in the Atlantic, we find the Azores closely parallel with the 
Hawaiian line; and the same is illustrated in the Canaries, ac- 
cording to the position of the islands given by von Buch,{ and 
also in the Cape Verds. These lines are also parallel with north- 
east South America, and the Pyrenees. ‘Thus, not only over one 
ocean, but over both, the same system prevails, and alike also 
over the intermediate continents, the one corroborating the other. 
The system in truth belongs to the world. ‘To this conclusion 
fo Necker, Boué, and other geologists appear to have at- 
rived. | 
But if we survey the facts more minutely, may we not find 
vexatious doubt, if they cannot be blended with the :

believe that instead of proving that there are as many distinet 
systems in orography as there are mountain courses,$ It W
