Temperature. 
A few temperature resemblances and contrasts which have come to 
light may be briefly summarised. In summer the departures of tempera- 
ture from the five years’ normal at MAlurdo Sound are the same as those 
at the South Orkneys, New Zealand, Perth (West Australia), and Rio 
Gallegos in Patagonia, and the reverse of those at Sydney (N.S.W.) and 
* Mean of Wellington, Hokitika, Lincoln, and Dunedin. 
t Mean of Diingeness, Punta Arenas, and Evangelists’ Island. 
X Mean at station -level, 619 metres above sea.
