Observations. 



Pressure. — The mean annual barometrical pressure (notwith- 

 standing the extraordinary wetness of the period, is greater than 

 that for many years past. 



Temperature. — The mean annual temperature fully confirms 

 what has been before advanced, that wet summers are generally 

 cold ; the whole of the monthly means, with the exception of 

 May and December, are unusually low. Indeed the actual defi- 

 ciency as to the annual amount exceeds 2-^- degrees. 



Winds. — These nearly agree with their respective numbers in 

 1 822, and what is more strikingly remarkable, those of the SW 

 exactly correspond. 



Rain. — As to rain and snow, the amount is nearly unprece- 

 dented, and for the last three years it has been rapidly increasing.
