gages were weighed fix feveral times ; In three of 
which the contents of the upper receiver exceeded 
thofe of the lower > and in the three others, the 
quantity in the lower exceeded that of the upper. On 
the whole, however, the contents of the lower rain- 
gage exceeded that of the upper above half an inch. 
This trifling diflference therefore feems to arife from 
a fliower’s lafting perhaps a little longer on the bot- 
tom of the mountain, and not from any permanent 
caufe, as in your obfervations. 
I am perfuaded, that thefe experiments have been 
made with the greateft attention and accuracy, as I 
was at Bala in Auguft laft, and found that all my 
diredions had been moft pundually followed. 
The inference to be drawn however from them 
(fuch as they are) feems to be, that the increafe of 
the quantity of rain depends upon its nearer approxi- 
mation to the earth, and fcarcely at all upon the 
comparative height of places, provided the rain- 
'i-ao-es are fixed at about the fame difiance from the 
ground. 
Poflibly alfo a much controverted point between the 
inhabitants of mountains and plains may receive a 
folution from thefe experiments ; as in an adjaceiit 
valley y at'kaft, very nearly the fame quantity of rain 
appears to fall within the fame period of time as 
upon the neighbouring mountains. I am. Sir, 
Your mofi faithful 
humble fervant, 
Dailies Barrington.
