„f high-water mark, Mr. Hull went on to remark that the new red sandstone from 
•Jit base of the red marls downwards consisted in this neighbourhood of four well- 
marked subdivisions, which are arranged under the following heads: 
1st. Waterstones. 
2nd. Upper soft red and variegated sandstone. 
3rd. Coarse red sandstone and conglomerate. 
4th. Lower soft red and variegated sandstone. 
!' has been demonstrated by the work of the Government Geological Surveyor*, 
these four subdivisions are constant along the borders of Wales, from the Mersey 
th* MaUerns, and extend thence into the central districts, where, though one 
a more of the subdivisions are occasionally absent, yet the struta which do occur 
''nvs present lithological characters by means of which they can he arranged under 
«'ia of these subdivisions. Through the knowledge obtained from this classifica-
