In the mammalian class the males possess rudiments of a uterus with the adjacent passage, in their vesiculae prostaticae; they bear also rudiments of mammae, and some male Marsupials have traces of a marsupial sack. The male Thylacinus offers the best instance.
Lastly, the law of the long endurance of allied forms on the same continent, of marsupials in Australia, of edentata in America, and other such cases, is intelligible, for within a confined country, the recent and the extinct will naturally be allied by descent.
Fish, batrachians, reptiles, mammals; in which latter are included the marsupials as well as lemurs, primates, Man. And after what struggles Man assumed an erect position and looked into the eyes of his mate! After Man? Nietzsche preaches that man is a link between the primate and Superman; Superman the angels!
Crows and hawks we carefully reserved to the last when all else should fail. The absence of kangaroos and other marsupials is a marked feature in this list, there being none on these wide-stretching downs." In January, 1879, the thunderstorms set in, and enabled the explorers to reach the line safely at Powell Creek Station. From here they travelled over known country to Port Darwin.
Their lower position is shown also by the fact that the temperature of their bodies is, at least, ten degrees Fahrenheit below that of higher mammals. One of these carries the egg in a pouch on the ventral surface; the other, living largely in water, deposits its eggs in a nest in a burrow in the side of the bank of the stream. After these came the marsupials.
The one is distinctly a true squirrel, a rodent of the rodents, externally adapted to an arboreal existence; the other is equally a true phalanger, a marsupial of the marsupials, which has independently undergone on his own account very much the same adaptation, for very much the same reasons.
The blacks believe profoundly in the bunyip, and white children, when very young, are scared with bunyip tales. There may have been once an animal answering to its description in Australia; if so, it does not seem to have survived. In Tasmania, however, are found, though very rarely, two savage and carnivorous marsupials called the Tasmanian tiger and the Tasmanian devil.
Waterhouse, of all Rodents, the bizcacha is most nearly related to Marsupials; but in the points in which it approaches this order, its relations are general, and not to any one marsupial species more than to another. As the points of affinity of the bizcacha to Marsupials are believed to be real and not merely adaptive, they are due on my theory to inheritance in common.
If ever an explanation lacked pertinency, it does so in this case, in which the succumbing group is represented by gigantic and well preserved animal forms, widely distributed and accustomed to the most varied methods of nutrition, whereas the competitor appears in the form of small, harmless marsupials. It would be equivalent to a struggle between the elephant and the mouse."
In the Miocene epoch, North America possessed Elephants, Horses, Rhinoceroses, and a great number and variety of Ruminants and Pigs, which are absent in the present indigenous fauna; Europe had its Apes, Elephants, Rhinoceroses, Tapirs, Musk-deer, Giraffes, Hyaenas, great Cats, Edentates, and Opossum-like Marsupials, which have equally vanished from its present fauna; and in Northern India, the African types of Hippopotamuses, Giraffes, and Elephants were mixed up with what are now the Asiatic types of the latter, and with Camels, and Semnopithecine and Pithecine Apes of no less distinctly Asiatic forms.
