 which refer to the limit of snow and the Torrid 

 Zone, as far as the special orders approach in their 

 extension, or, on the contrary, recede from them. 

 Where, according to well-known observations, an 

 order or genus peculiarly occurs, the name and the 

 lines are engraved. These lines, when supposed to be

As the world of organized beings, within a certain 

 district in the Equator, is distinguished by a propor-

 drawn up to a certain extent, lying around the very
