The above table appears to add further confirmation to 
the remarks made on the rainfall at Old TrafFord by Mr. 
G. Y. Vernon, F.R.A.S., F.M.S. at the last meeting of this 
section. There is perhaps one thing worthy of notice, viz., 
that the average annual difference of rainfall between Old 
Trafford and Eccles for 6 years is about half an inch. This 
year the difference is not quite one tenth of an inch. The 
difference between the height of my former station above 
the sea and my present one is 27 feet. This probably 
may account for my having measured a trifle more rain 
during the last five months. 
I now present the monthly amounts that fell into each 
gauge, and the number of miles of the horizontal movement 
of the air.
