horizontal funnel and the inclined funnel ; but during the summer 

 months it failed in doing so, that failure being greatest in August, 

 when it had taken 0.536 inches less than the mean of the other 

 two gauges. In the twelve months the globular gauge had taken 

 1.503 inches less than the mean of the other two gauges. 



Fourth, The funnel, which had a diameter of 18 inches, re- 

 ceived 2.505 inches less rain than a funnel 12 inches in diameter, 

 which was placed at the same height. And this difference was 

 not the effect of one or two months; for it will be observed, on 

 reference to the Table, that the quantity received by the larger 

 funnel was uniformly less than the quantity receivedby the smaller. 



These results were obtained at Harraby, near Carlisle.
