The average rainfall at tliis station for February is ;3--iS iuelies, 

 and the average temperature 39*4 degs. The rainfall of less than 

 two inches in a mouth has been taken as representing a dry 

 month, and over four inches as a wet month. Curiously enougli, 

 loet, dry, and what may be ternieil irregular, seem to form a con- 

 current series of years. The yeai-s 1 8G0 to 1865 inclusive have 

 been disregarded, as they appear to form part of an irrei/tdar 

 scries — if there is any truth in this assumption, and only a long- 

 series of observations could settle this point. Commencing with 

 1866 to 187:2 (seven years) we have a wet series. Tliere is an 

 exception here — viz., 1867 — the rainfall in this year being below 

 the average.

An irregular series of six years follows — 1873 to 1879 — in 

 which the rainfall and temperature are very nearly the average.
