For comparison with the above, I now give weather statistics from two stations 
in nearly the same latitude as Macquarie Island. One, Orange Harbour, is situated in 
the extreme south of South America; the other, South Georgia, lies about 1,000 miles 
to the east. These I have taken from Dr. Skottsberg’s interesting memoir “ On the 
Zonal Distribution of South Atlantic and Antarctic Vegetation” (Geographical Journal, 
vol. 24, pp. 655 to 663).
