In the next table is given the results obtained from rain- 
gauges of two different kinds placed in close proximity in 
the same plane and 3 feet from the ground. The one has a 
lOin. round receiver and the other a 5in. square receiver. 
The large receiver had an excess over the small one in most 
of the months of the year, the exceptions being J anuary, 
July, August, and October. The total difference of the fall 
in the two gauges was very small, being even less than the 
difference in 1872. The total difference in 1872 was over 
four tenths of an inch, but in 1873 it was barely over three 
tenths of an inch. And an average fall in both gauges over 
a period of six years shows a difference of only about the 
same amount. Thus the two gauges, though of different 
characters as regards their receivers, are good checks upon 
nach other.
