Meteorological Observations for January 1 828. 337 



eleven days of frost. We have had thirty-two wet days more in this 

 year than in 1826, and the quantity of rain is greater by 14*926 

 inches. The writer of these remarks has carefully registered obser- 

 vations on the weather in this town for upwards of five years. He 

 subjoins a summary from 1823 to 1827, both years included. From 

 observations made by the late John Gough, and by John Dalton of 

 Manchester, he inferred the mean annual quantity of rain for Kendal 

 was 51*8 inches. The average for the five years alluded to, will be 

 found to be 57*310 inches. The difference may arise from two causes : 

 — one, the difference of altitude in the places where the observations 

 were made, above the level of the sea ; but though that does not 

 exceed many yards, yet even so small a difference will affect the 

 amount of the mean in a series of years. The observations from 

 which the former mean was calculated, were taken from twenty dif- 

 ferent years, though not twenty successive years. Assuming all the 

 observations to be equally correct, the mean deduced from the twenty- 

 years is most likely to be the correct one. There are few places 

 where rain-gauges are kept, that have so great a quantity of rain as 

 at Kendal, though it is probable that in many places there are more 

 rainy days within the same period. From a number of observations 

 now in my possession, the annual mean quantity of rain which falls 

 in England, may be stated at 352 inches.
