the globe ; a continuous one there probably is not, but when we view 

 amidst all the differences that undoubtedly do occur in the super-posi- 

 tion and connections of rocks, the many and wonderful coincidences 

 that still remain, not confined to a spot of limited extent, but clearly 

 belonging to the whole tract, we shall be satisfied that the contempora- 

 neous formation cannot be predicted of these masses in which such 

 resemblances are found ; at least they must be attributed to a common 

 origin. When we read in Humboldt, that while in different countries, 

 different plants and animals present themselves to the observation of 

 the naturalist, the rocks are the same in every zone ; in every climate 

 we appear to be engaged * * * * *

 always the same wherever occurring, why should granite always con-

 however distant the localities ? mica slate, mica and quartz, and so on 

 of others. These are questions difficult to answer, but which none can 

 avoid asking themselves who have ever reflected on the subject.

 with that [of the] Andes. But it bears a [very] close resemblance 

 in general features to the description given us by Dr. Macculloch, of the 

 Western Isles. As on those Islands, so here we recognise the great ex- 

 tent of gneiss occupying in each system the middle and highest tract. 

 In the great deficiency of granite, we see another resemblance and a 

 common difference from the dogmas of the schools, that the highest 

 part of every system of mountain *****

 this point between the primary and secondary rocks. But the most 

 interesting coincidence, at least to me, is in the arrangement of the 

 schists, and their connections with the other rocks. In his chapter on 

 the chlorite series, he has almost completely anticipated every thing I 

 had to say on the chlorite schists of the Himmalaya.
