Note 95 — Chapter X · THE LOWER ANIMALS.
Reading edition
The interesting discovery, by Mr. Beale and others, of several species of mammalia in the Purbeck, and that of Professor Emmons of a mammal in rocks of similar age in the Southern States of America, do not invalidate this statement; for all these, like the Microlestes of the German trias and the Amphitherium of the Stonesfeld slate, are small marsupials belonging to the least perfect type of mammals. The discovery of so many species of these humbler creatures, goes far to increase the improbability of the existence of the higher mammals.
