47. Insects of the Coal. 48. Fishes of the Carboniferous System. 49. Retrospective Summaiy of the Flora of the ancient World. 1. Introduction. — The examination of the recent and fossil zoophytes, which formed the subject of the last discourse, will enable us to comprehend many of the phenomena relating to the ancient coralline rocks hereafter to be noticed. I now resume the geological argument from which we have for a while digressed, and hasten to the con- sideration of the Carboniferous syst...em, which in the chronological arrangement (page 179, PL 3, THE CARBONIFEROUS SYSTEM. 521 fig. 7) succeeds the saliferous deposites described in the Fifth Lecture. The strata comprised in the Carboniferous sys- tem, so named from its being the great depositary of that important substance called coal, admit of three natural divisions. The uppermost is com- posed of a vast number of alternations of coal, shale, ironstone, and sandstone; the middle, of limestone, chert, and sandstone, with immense quantities of shells, polyparia, crinoidea, and other marine exuviae^; and the lowermost, of sandstones and conglomerates, generally of a dull red colour, and bearing some resemblance, in their lithological characters, to those of the new or upper red sand- stone.
