ines could notbe drawn across this table in such a way as to divide it into sectionsrepresenting the Fauna of the various geological periods. In order toshow that, a very different table would require to be constructed inwhich distance along a line stretching upwards from the base* wouldindicate merely the age of the group and not evolution or advance inorganisation as in the present table. Degeneration could not berepresented, and it would be impossible to distinguish except, perhaps,by colour, between groups which had undergone rapid evolution andthose which had remained comparatively stationary. * In such a table the Foraminifera and other groups of Protozoa would extendfrom the base to the top of the table, although they have undergone comparativelylittle evolution. Some of Haeckels phylogenetic schemes (see Generelle Morpho-logic der Organismen, Berlin, 1866) are of this palaeontological nature and show theprobable distribution in time of the various groups of animals and plants.
