OBSERVATIONS ON THE FALL OF RAIN. 189 
upon as rules to guide us in the application of our 
knowledge to the purposes of life. 
In the consideration of this question, it is im- 
portant also, to observe the position of the gauges 
by which the depth of rain is measured. It is 
now sufficiently notorious from the number of 
experiments which have been made, that gauges 
placed at different elevations, abruptly raised 
from the ground, indicate a less fall of rain the 
higher the -gauge is placed. For instance, a 
gauge placed on the top of a house, shows less 
rain than one placed on the ground immediately 
below, and another situated at the top of a 
contiguous steeple, indicates less than that on the 
top of the house. 
From this fact, which seems clearly established, 
it has been contended, that less rain will fall on 
elevated than on low land. The observations 
which have been detailed in this paper, clearly 
show that this is not the case, and most other 
observations within the region of the clouds, 
where the proper position of the gauge has been 
attended to, show the same result, although local 
circumstances vary the depth of rain in particular 
vlaces amongst the hills themselves.
