This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed.

II.--Gymnosperms. 6. C0rdaitew. 1. FiIice.s-.--Ferns are amongst the oldest known plants. They increase in number both as regards individuals and species as we go back from the present day to Carboniferous Times, in which they attained their maximum development, and outnumbered all other known Coal Measure plants. They are also abundant in the old Red Sandstone rocks, which are older than the Carboniferous, but none have yet been found in earlier deposits than these. The parts of fossil ferns which are most commonly preserved are the stems, leaf-stalks, and leaves, which are generally more or less fragmentary. A few fossil ferns are found in Goyt Valley, but, though generally abundant in the Coal Measures, they are here not common. 2. Cala1narz'a: .--The Calamites (calamus, a reed) are now entirely extinct. They have been known for a long time, but chiefly in the form of casts of the hollow pith of the stem. These casts have such a strong superficial resemblance to modern horsetails, that earlier geologists unhesitatingly placed them near this group. Specimens shewing internal structure have now been found, and this confirms the views of earlier authors as to their aflinities. The cylindrical casts of the central pith of the stem are covered with longitudinal flutings, interrupted at intervals. Formerly these casts were compared to the ribbed stems of horsetails, and to reeds, but it has now been shewn that they are casts, not of the whole stem, but only of the central pith cavity; for specimens have been found in which the wood may still be seen encircling the fluted' cast.
