vigators call them, are still far north of the Antarctic Circle ; whereas 

 in the Northern Hemisphere in 70 of latitude, at the extremity of 

 Scandinavia, fir-trees attain a height of between 60 and 70 English 

 feet. (Compare Darwin in the "Journal of Researches," 1845, 

 p. 244, with King in vol. i. of the Narrative of the Voyages of the 

 Adventure and Beagle, p. 577.) If we compare Tierra del Fuego, 

 and particularly Port Famine in the Straits of Magellan in lat. 53 

 38', with Berlin, which is one degree nearer the Equator, we find for 



-0 5 30. 8 



Berlin 6.8, ~I^TQ R-, 47.2, -^-^ Fahr,; and for 



1P.2 34.8 



Port Famine 4.7, -J^-Q K, 42.6, ^~Q Fahr. 



I subjoin in one view the few well-assured temperature data which we 

 at present possess, for the lands of the temperate zone in the Southern 

 Hemisphere, and which may be compared with the temperatures of 

 the Northern Hemisphere, in most parts of which the distribution 

 into summer heat and winter cold is so different and so much less 

 equable. I employ the convenient method of notation before used 

 and explained in pages 113114.
