One of the most remarkable phenomena displayed to usby the researches of the geologist, is the evidence of theexistence, in primaeval times, of animals and plants, theanalogies of which are now rare or wanting on our landsand in our seas. Among those tribes which have become allbut extinct, but which once presented numerous generic mo-difications of form and structure, the order of Crinoid Star-fishes is most prominent. Now scarcely a dozen kinds ofthese beautiful animals live in the seas of our globe, and individuals of these kinds are comparatively rarely to bemet with: formerly they were among the most nnmeronsof the oceans inhabitants,—so numerous that the remainsof their skeletons constitute great tracts of the dry land asit now appears. For miles and miles we may walk overthe stony fragments of the Crinoidesc ; fragments whichwere once built up in
