To quickly assess the difficulty of the text, read a short excerpt:
The marsupial pouch the characteristic feature of the class has, it is true, become reduced to a few unimportant folds on the abdominal skin. Still, because of the number of their teeth, and because the earlier fossil Mam- malia show most affinity to them, they must be regarded as the least modified members of the family. The Didelphidae, or Marsupial Eats, are now confined to southern and central America. Neither geology nor palaeontology gives us any clue as to how this has happened: whether ...and when this branch separated from the main group confined to Australia : whether the agreement of the Didelphidae with the other Marsupials is a matter of converg- ence : or whether the Australian Marsupials are of American origin. However, we shall have to return to this latter supposition owing to an anatomical peculiarity. The dentition of the Marsupial Eat shows most resemblance to our Insectivora, and they also agree with them in many ways as regards mode of life and food. Even Cuvier discovered their fossil remains in the Eocene strata of Paris.
