Temperature. 



Thermometers are exposed in a Stevenson screen. 



Precipitation. 



It has been found that the rain gage at Darwin Post Office 

 gradually developed defects apparently between 1922 and 

 1928, which defects were undiscovered until February i, 

 1940, when a new gage was issued. A comparison with 

 rainfall recorded at another station in Darwin has led to 

 the rainfall figures at the Post Office being increased by 

 20 percent. Such adjusted figures are here published for the 

 decade 1 931 -1940, and the figures given in Smithsonian 

 Misc. Coll., vol. 90, for the period January 1927 to De- 

 cember 1930 should be increased by 20 percent. The neces- 

 sity for these adjustments makes the homogeneity of the 

 records for 1921-1940 rather doubtful.
