''Results of Rain Gauge Observations, made at Eccles, 
near Manchester, during the year 1875,” by Thomas Mac- 
KERETH, F.R.A.S., F.M.S. 
The rainfall of last year was above the average, by a 
little over the amount which fell in July above the average 
for that month. Hence it may be said that the excess of 
rainfall for the year was due to the excessive amount which 
fell during July. Great excesses fell during June and Sep- 
tember, and the fall during all the summer and autumn 
months was invariably above the average. The fall was 
greatly below the average in February, March, April, and 
December, so that the year was characterised by a dry 
spring and a very wet summer and autumn, though the 
excess of the rainfall of the year is about the average fall 
for a month at this station, yet the number of days on which 
rain fell is below the average. This usually happens during 
the periods of excessive rainfall, which shows how much 
more rapidly the clouds condense during periods of heavy 
than of light rainfalls; and is another instance of a rule in 
rainfall that I pointed out last year. The following table 
shows the results obtained from a rain gauge with a lOin, 
round receiver placed 3ft. above the ground.
