498 Meteorology, 
period from a quarter toa third of a century ; 
but T prefer haying his results separate, for 
the following reasons. On a comparison of 
our results for 8 subsequent years, I found 
his average exceeded mine, by about 4 
inches in the year. (See Memoirs, Vol. 5, 
page 668), On inspecting his gage, I had 
reason to think his mode of measuring the 
rain was not susceptible of sufficient accu- 
racy, and suggested the same to him, with 
which he seemed to acquiesce. Besides this, 
the year 1792, (one of the eight), was a 
most remarkable one, in the north of Eng- 
land particularly. The annual depth ex- 
ceeded the average amazingly; and it was 
occasioned by an excess, in two or three of 
the months chiefly. The rain at Kendal that 
year was nearly 85 inches ; and it was nearly 
the same at Keswick. April produced 10 
inches, September 11, and December 12 
inches. Mr, Walker’s rain in Manchester 
that year was 554 inches, which is far above 
the average; and nearly one half of this 
great quantity fell in three months, namely, 
May, September and December. The year 
1789 was also unusually wet. These facts 
influence the annual and monthly averages of | 
Mr. Walker materially, independently of any 
supposed error in the actual measurement. __
