OBSERVATIONS. 



Pressure. — The greatest range of the mercury, which is 

 nearly that for the year, took place in December, and notwith- 

 standing the amount of rain, the spaces described in inches 

 and the number of changes in the direction of the column, are 

 less than usual, while the mean is higher than for some time 

 past. 



Temperature. — The mean temperature for the year just 

 elapsed is 1° higher than that of the preceding one. The 

 months of April, May, August, September and December, 

 were considerably warmer in 1821 than the corresponding 

 ones of last year, while the three first months, and June and 

 July, are as much the reverse. The means of October and 

 November in both periods are nearly alike. 



Rain. — The amount of rain exceeds that of last year up- 

 wards
