THE NEW RED SANDSTONE.

distinguished from the New red (or Triassic) gravels, by their more irregular heaped-up method of deposition; by the sand in which the pebbles lie being of a paler and yellower colour than that of the New red; by the pebbles lying edgeways and confusedly, instead of horizontally and more or less regularly stratified; by the pebbles being often dirty, while those of the New red are generally quite clean (a remark of Mr. Hull's), and by a vague but sufficiently appreciable facies, which is not describable, but can be learnt by a little practice, and by that alone.
Figures 1 and 2 represent two modes of occurrence of the conglomerates in the New red sandstone.
