“ Result of Rain-Gauge and Anemometer Observations 
made at Eccles, near Manchester, during the Year 1868,” by 
Thomas Mackereth, F.R.A.S., F.M.S. 
The following amounts of rainfall are obtained from two 
gauges 8 feet from the ground and 145 above mean sea 
level, and one gauge 84 feet from the ground. One of the 
lower gauges has a round receiver lOin. in diameter, the 
other has a 5in. square receiver ; the edges of both are turned 
inward. These two gauges stand close to each other, 75 feet 
from my house or any building, and free from every obstruc- 
tion. The higher gauge has a 5in. square receiver, like the 
one near the ground. It is 4 feet above the ridge of my 
house and free from every obstruction. First I represent 
the rainfall for 1868, as measured by the lOin. gauge. This 
I have compared with the average fall for 8 years at Eccles.

This table shows that though the Spring and Summer 
months were so exceedingly dry, yet the rainfall for the year 
was only about 1 Jin. below the average fall of 8 years. The 
wettest months, as is usual, were at the beginning and end 
of the year. In this respect the rule of rainfall for this dis- 
trict was not departed from. The departure from rule is to 
be found in the rainfall of the Summer and Winter months 
especially. The one in its deficiency, the other in its excess.
