68 ON THE GEOGRAPHY OF ANIMALS. 
(95.) The islands dispersed in the great gulf, but 
more particularly the Isthmus of Mexico, constitute 
that intermediate region — that ‘‘ land debateable” — 
in which the Faunas of the two great divisions of 
America meet, and imperceptibly blend into, each other. 
Such are the harmonious transitions of nature through 
all her works; ever varying, her laws are yet the 
same, in whatever light her operations are studied. 
To look for absolute divisions were a fruitless and a 
hopeless task, for they can never be found; and they 
appear totally repugnant to the laws of creation. It is 
immaterial, therefore, to our present purpose, at what 
degree of longitude or of latitude we draw an imaginary 
line of separation ; whether, in short, we consider the 
table land of Mexico as the southern confines of tem- 
perate America, or view it as the northern limits of its 
tropical portion. As a combination of circumstances 
has drawn our attention to this hitherto unknown re- 
gion, a more detailed notice on such of its animal pro- 
ductions as have yet reached us, may prove interesting. 
(96.) On the quadrupeds of Mexico, our information, 
indeed, is but scanty. The short and vague notices 
given by Hernandez, who distinguishes them only by 
the unutterable names of the Indians, affords no clue by 
which we can comprehend their real nature ; and, un- 
fortunately for science, the most intelligent and accom- 
plished of our modern travellers in Mexico— one who has 
supplied us with a fund of most important and ster- 
ling information on nearly every other topic — had no 
knowledge of natural history. Nevertheless, Mr. Ward * 
occasionally alludes to some of the native quadrupeds. He 
mentions herds of between fifty and sixty deer, as abound- 
ing on the plains of the table-land T: he alludes to wolves 
being caught by the lasso ; and to a kind of fox or wild 
dog, which is found in such numbers, that the hunting 
parties, formed by the peasants, frequently kill great 
numbers in one season.{ ‘ The wild animals to be met
