The weather during the month has been clear and cold, with barometer rather 

 above the average, and prevailing westerly winds. Rain fell at Sydney on seven 

 days ; but the amount is 1-456 inch below the average of this month. The excessive 

 quantity of ozone, 2-2 above the average is remarkable, considering the prevalence of 

 westerly winds. Generally along the coast a moderate quantity of rain has fallen, 

 ranging from 2 to 9 inches ; but inland the month has been very dry, and in many 

 places the drought stiU continues. The minimum barometer at Sydney occurred on 

 the 16th, followed by a cold W.N.W. gale and lightning at night. On the l7th 

 enow fell at Orange, Goulbmn, and Cooma. On the 22nd a very high tide visited 

 Sydney.
