This month was very dry; the days hot for the period of the 

 season and the nights cold and often frosty. In 1 2 of the latter 

 the thermometer was at, or below the freezing point; but 18 

 nights were indicated by the Radiating thermometer as being 

 more or le^s frosty. The baron eler stood high. The amount 

 of rain was less than in any corresponding month for at least 

 19 preceding years, with the exception of 1842. The degree 

 of dryness as indicated by the hygrometer was unusually great, 

 especially on the 9th, 10th, 26th; and on the 30th, it attained 

 almost the highest pitch of dryness ever observed in this 

 country.
