General Mean - - 35. 2 



This general mean of 35. 2 inches is, I apprehend, a little Mean quantity? 

 above the medium for England and Wales, as the greater of rain » 

 number of places are thofe where much rain falls. If we take 

 a mean for each of the above-mentioned counties (where more 

 than one place in a county is given) and then a general mean 

 from the counties, the refult is a reduced mean of 31. 3. Even 

 then it may be objected that the greater part of the counties 

 are maritime ; but it mult be obferved, that there is no ac- 

 count of rain in Wales ; and we may fafely conclude, that 

 the rain in Wales would exceed the laft-mentioned mean as
