CONCLUSION. 135 



eitherin regard to its mineral characters or mode of connexion 

 with others. Notwithstanding that an observer spends much 

 time in investigating a given tract, and pursues his labour 

 with much alacrity and diligence, still when he has completed 

 his survey, though he has travelled through the country in 

 every direction, having climbed its mountains and perambu- 

 lated its valleys, coasts, and streams, some points, perhaps, 

 even of considerable interest, may have been passed over by 

 him unobserved. Aware of this, however, we sincerely hope, 

 that though geologists, in examining the district which we 

 have been considering, may find appearances which we have 

 not described, they will not, when comparing our descrip- 

 tions with phenomena in the field, discover that in any 

 instance we have misunderstood what we saw. Through- 

 out the whole of this paper, we have endeavoured to state, 

 in the most concise manner, what we considered requisite 

 to notice, doing this from a conviction, that in writing upon 

 natural appearances, a multiplication of words is to be par- 

 ticularly guarded against. In conclusion we may only re- 

 mark, that if we have endeavoured to advocate doctrines 

 considered as erroneous by some observers of celebrity, and 

 have differed from others in descriptive details, we have in 

 the one case done so from no love of disputation, and in 

 the other, from only finding in the district which we have 

 examined appearances which seemed to us capable of being 

 only seen in one way.
