and great magnificence. As heat and moisture princi- 
pally tend to the increase of vegetation, and to its lux- 
urious developement, so is the latter always accompanied 
by a corresponding exuberance of animal forms: both 
are in their highest developement in equinoctial latitudes, 
and both progressively diminish towards the poles. 
It is, consequently, in the southern provinces of India 
that all the features of Asiatic zoology are most con- 
spicuous. 
(66.) Commencing with the quadrupeds, we find a 
striking characteristic of this region, in the numerous 
but disgusting race of apes and baboons ; of whose ex- 
istence in Europe, even at the most remote period, there 
is not the slightest record. These satyr-like creatures 
seem to congregate as we advance to the equinoctial 
line: the long armed gibbons being principally found 
on the isthmus of Malacca, while the oran-outangs ap- 
pear more especially to be natives of the great islands. 
The subgenera Hylobates, Presbytis, Nasalis, and Sim- 
nopithecus are peculiar to this hemisphere, which has 
already furnished twenty-three species of these apes and 
baboons. The analogy between the animals ef Equi- 
noctial India, and those under the same latitudes in 
Africa, is here very strikingly illustrated. The apes 
and baboons of the latter continent occur under similar 
degrees of latitude, and, in several instances, belong to 
the same genera, but the number is greater. Yet, as 
a proof how truly distinct are the two zoological pro- 
vinces, we may remark, as a singular fact, that only one 
species has yet been discovered as a native inhabitant 
of both; this is the grey baboon, whose geographic 
range is also removed from the equator ; being found at 
Moco, the Persian Gulf, and in Arabia ; countries lying 
on the confines of the two continents. These parallel 
analogies, or mutual representations, are always highly 
interesting. Thus we find the Indian oran-outang, ty- 
pified on the African continent by the Chimpanzee, con- 
sidered by Linneus as a wild man, and still affirmed,
