NOTES ON THE METEOROLOGY OF COCKERMOUTH. 



By Henry Dodgson, Esq., M.D., F.R.A.S., (Cockermouth). 



This paper comprises a summary of Meteorological observations 

 taken at Cockermouth during the fifteen years, from. January 1862, to 

 December 1876. 



The instruments observed w^ere the barometer, wet and dry-bulb 

 thermometers, together with self-registering thermometers for recording 

 the maximum and minimum temperatures both in the shade and on the 

 grass. The rain-fall was also noted, as well as the amount of cloud and 

 of ozone; and the direction of the wind with its apparent force recorded. 



All the observations were made twice a day — at 9 a.m., and 9 p.m., 

 — except that the rain-fall was in general only measured once a day — at 

 9 in the morning. 



Barometer. 



In giving a summary of the readings of the Barometer, there is 

 nothing very noteworthy to record, since the atmospheric pressure is pretty 

 uniform over the British Isles : there being a small but gradual diminution 

 of pressure from south to north. 



The mean annual height for this latitude is about 29-9 inches; and 

 my own observations agree very well with this, the mean I obtained for 

 the 15 years being 29-876 inches. 



In the first table I have given the mean pressure for each year of 

 the series together with the highest and lowest observed during that year. 



It is very common for persons who are in the daily habit of observ- 

 ing the Barometer as a "weather glass," but without keeping any record
