The mineralogical centre of this section is at North Sannox, and 

 the lower red conglomerate is there seen in several situations, rising 

 to the height of about 1 000 feet above the sea. 1 . This formation is 

 supposed to be identified with the old red sandstone ; from its lowest 

 members graduating into grauwacke ; from its containing concretionary 

 limestone not distinguishable from the cornstone of Herefordshire ; 

 and its being regularly overlaid by the carboniferous series. 2. The 

 middle deposit of the section is clearly referable to the carboniferous 

 series, by its mineralogical structure, by the organic remains in the 

 calcareous beds, which are identical with those of the mountain- 

 limestone ; by its containing seams of coal, which have been worked ; 

 and by the plants in the shale being of the same species with many 

 of those most abundant in the coal-measures of England. 3. The 

 superior sandstone and conglomerate are of enormous thickness, rising 

 into lofty and precipitous hills upon the coast. These are referred to 

 the new red sandstone, from their position and internal characters ; 

 and this classification is confirmed particularly by the structure of the 

 sandstone on the southern coasts of the island. This formation differs 

 however from the new red sandstone of England, not only in being 

 conformable to the beds on which it rests, but also by graduating into 

 the superior parts of the carboniferous order. 



In conclusion, the authors endeavour to show, that the great dis- 

 locations of the secondary deposits have been produced by an up- 

 heaving of the granite ; and they state, in corroboration of this 

 opinion, that where the breaks .in the strata are greatest, there the 

 granite makes the nearest approaches to them. It is further attempted 

 to be proved, that the granite could not have been in a perfectly fluid 

 state at the period of its elevation, from the fact of its existence in 

 the form of mural and serrated precipices on the flanks of the se- 

 condary strata j being in this respect prominently distinguished from 

 the trap of the southern regions of the island, which has, in number- 

 less places, not only penetrated, but overflowed upon the new red 

 sandstone.
