POSTSCRIPT. 
SINCE my writing the foregoing, I have thought 
on a Method of keeping the Meteorological Tables 
therein propofed, whereby the Work will be very much 
contra&ed. This is, inftead of conftru&ing the Tables 
according to the Oceans whereon the moft confiderable 
Trade of the World lies, to frame them only according 
to the Route of the moft common Voyages on thofe 
Seas. Thus, may one of the Tables be contin’d to that 
Part of the Atlantic k Ocean y which fuch Ships gene- 
rally pafs over, that Trade between Great -Britain and 
the Weft Indies •, another Table for thofe Parts of the 
Ocean , that lie in the Paffage of fuch Ships as are enga- 
ged in the Mediterranean , or Turkey Trade , to which 
may be added a Table for the African , and India 
Commerce. Another Table may be framed to that 
Part of the Ocean , that lies between the Northern Pro- 
vinces in America and the Weft Indies \ as alfo one 
for the Ships that pafs between New-England , and 
H h h New •
