37. It should be noticed, however, that the term line is incorrectly 

 used, or at least with great latitude, and even substituting that of plane, 

 it is still necessary to bear in mind, that its direction, whether as referred 

 to a great circle, or the loxodromic curve, is by no means uniform, 

 or even regular in its deviations ; unless indeed we regard it as of con- 

 siderable breadth, and in that case its surface would be very irregularly 

 studded with peaks. In this way we may certainly affirm, that it is 

 parallel to the common boundary of mountain and plain land. In fact, 

 it is impossible to contemplate such masses disposed along such a dis- 

 tance without feeling convinced, that there is some connection between 

 the greatness of their elevation, and the original formation of the moun- 

 tain systems in which they are found. The parallelism becomes more ob- 

 vious when we consider a more extended tract.
