 all humility re-echo the interrogation " where 

 wast thou when I laid the foundations of the 

 earth ! declare, if thou hast understanding ! " yet 

 revelation teaches us, that all created beings were 

 inhabitants originally of the same district ; and 

 again, that all animals were collected a second 

 time into one spot at the deluge. This, then, we 

 are bound to believe ; but how are these facts 

 reconcilable with those which have been above 

 stated that each tribe of animals requires a pe- 

 culiar temperature, and that each is now a deni- 

 zen of certain districts alone ? In my opinion, 

 they are easily so, if we keep in mind first, that 

 every variety of temperature is procurable by 

 differences in the elevation, under precisely the 

 same latitude ; and, secondly, that there are no 

 assignable limits to the power which animals 

 possess of migrating from one district to another. 

 With respect to the former position, it is very 

 well known, that in Quito, one of the mountains 

 of the Andes, within a space of twenty miles, all 

 the various temperatures of the globe are found. 

 At the base is the torrid zone and the plants and 

 animals of that region ; farther up, is a tempe- 

 rate climate ; and still higher, is the frozen at- 

 mosphere with the soil and products of arctic 

 countries. A similar remark may be made with 

 respect to the Alps ; and so decided are the dif- 

 ferent climates on the declivity of the Peak of 

 Teneriffe, that the whole has been divided into 

 five distinct zones, called respectively accord-
