»des Fortschrittes sind es nicht diese” (europäischen) »miocânen | 
oder eocänen Schichten, sondern die von pliocänem oder 
»pleistocänem Datum in mehr am Aequator gelegenen Gegenden 
»in denen wir am meisten hoffen dürfen, später einige höher or. 
»ganisirten Affenarten als Gorilla und Chimpanze aufzufinden." (4 | 
Warrace laat zich aldus over de zaak uit: »lt is very 
„remarkable that an animal so large, so peculiar, and of such 
»a high type of form as the Orang-utan should be confined tos - 
»limited a district — to two islands, and those almost the last 
»inhabited by the higher Mammalia; for eastward of Borneo and 
»Java, the Quadrumania , Ruminants, Carnivora and many other 
»groups of Mammalia diminish rapidly , and soon entirely disap- 
»pear. When we consider farther that almost all other animals 
»have in earlier ages been represented by allied yet distinel 
»forms — that in the latter part of the tertiary period, Europ 
»was inhabited by bears, deer, wolves and cats; Australia by 
»kangaroos and other Marsupials; South America by gigantit 
»sloths and anteaters: all different from any now existing, though | 
»intimately allied to them — we have every reason to believe 
sthat the Orang-utan, the Chimpanzee and the Gorilla have als? | 
»had their forerunners. With what interest must every naturalist 
| 
| 
»look forward to the time, when the caves and tertiary deposit 
»of the tropics be thoroughly examined, and the past histor? 
^and earliest appearance of the great manlike apes be at length 
»made known.” (2)
