(No. 6) will shew. For instance the amounts from W. and S, 
are nearly equal, and both less than S. W.; N. E. and S. 
still less; N. and E. still decreasing ; and N. E. the least of 
all. Whether this analogy between the barometric pressure 
and amount of rain is accidental or not remains to be proved. 
The following table shews the numerical average of the 
rain. The detailed tables and curves will be published in the 
Transactions of the Academy.

There is one particular in which this separating the gross 
amount of rain into the eight portions, as brought by dif- 
ferent winds, may be useful, viz., to ascertain the respective 
specific gravities, and the amount of saline matter brought 
from each direction; this may be useful in regard to agricul- 
tural matters. For instance, we could easily suppose a case 
of two portions of land, not many miles asunder, but on dif- 
ferent sides of a high range of hills, getting very different 
amounts of salt from one being exposed to, and the other 
sheltered from that wind in which the greatest amount was
