To make the subsequent descriptions clear, the author first gave 

 a normal or typical section of the older Palaeozoic rocks, by enume- 

 rating (in an ascending order) the great groups which have been 

 well established, as follows: — 1. Skiddaw Slate. 2. Chloritic slate, 

 porphyry, trappean shales, &c. 3. Coniston Limestone, calcareous 

 slate, Coniston Flagst( ne, &c. (All the above three groups are called 

 (Jambrian.) 4. Coniston Grit, — a good physical group, which how- 

 ever, from the paucity of its fossils, may be thought of ambiguous 

 relations: it appears to represent the May Hill Sandstone, and there-
