" The predominance of the SigiUnria and Stigmar'm in the Middle Coal formatinii, proves the identity of tliis zone with our European zone of Sigilliiria; and the analogy with the flora of the principal of coal of England and Ireland is particulary striking, especially through t'.ie great extension of the Alethopteris lunchilica, which is never wanting there. " When, fiiiiilly, Dawson sets forth in a prominent manner, that in the uppermost division .)n, trunks of conifers and Calamites, Cal, ISiirliorii, dc, and O. approximalns, by the side of Aspidiaria, etc., are the fossils most frequently to be met with, we arc enabled to place this zone nearly on a level with the zone oi Calamites, or the third band of vegetation in Germany. " Tims tlic succession in the flora of the Coal formation, as we have ascertained it for Europe, appears to have been established for America also by l)r Dawson's profound investigations, and tiiey will probably soon be followed by tiie discovery of the existence of the two upper zones,âthe 'â Anmdaria' and 'Fern' zones," It will be observed that Professor fieinitz anticipates the separation of two additional zones in the Upper Coal formation, vjf tliese I have as yet no distinct evidence, and the paucity of fossils in these Upper rocks may render it difhcult to make such distinctions. Un- doubtedly, however, Anmdaria galioides, Cordaites simplex,, and several ferns, as Pecopteris arborescciis and Alethopteris nervosa, are char
