62 PICTURE OF ORGANIZED NATURE. 



the 50th and 57th degree N.L. ; the S. Surinamensis, 

 Surinam; the 8. murinus, Java. The common 

 Hedgehog lives in the warmer parts of Europe : it 

 is found in Norway, but neither in Lapland nor 

 Iceland. The Tendrac inhabits Madagascar. These 

 Genera of animals do not seem to go further than 

 the 5th degree on this side of the snow-line. 



19. Opossums (Didelphis) inhabit the warm coun- 

 tries of America and New Holland, in the Southern 

 Hemisphere, extending nearly as far as the 40th de- 

 gree S.L. 



20. Bats (Vespertilio), Schreber believes, extend 

 over the whole earth. It is however improbable 

 that they should come near the snow-line, because 

 they sleep, during the winter, in the Temperate 

 Zone. The common Bat (V. murinus) extends to 

 Norway ; but in Lapland, Iceland, Greenland, Hud- 

 son's Bay, and on the tracts in the vicinity of 

 the Frozen Sea, there are not any. Zimmermann 

 supposes the limit to be in the 63d degree N.L. In 

 our Picture it has been placed in the 65th degree. 



DORMICE (Glires) are numerous in the Tempe- 

 rate Zone ; become more so in the Torrid; and ex- 

 tend towards the snow-line, without reaching it ; at 

 least, no species is peculiarly common to the neigh- 

 bourhood of the snow-line.
