(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
