in our Longitude, reach to 45 Degrees of North 
Latitude, which is about Bordeaux. If we fhould 
fuppofe the whole Breadth of the Trade-wind to 
confift of an infinite Number of parallel Lines, fall- 
ing on a Surface of the fame Inclination, then the 
- reflected Lines will be all parallel, and confequently 
the Angles will be all equal 5 but they will reach 
wider, according to the Diftance of one Point of 
Contact from the other j fo that if that Line, which 
fell on the fuppofed Surface under the Equator, be 
refleded to 45 Degrees North Latitude, that which 
fell on the fame Surface to the North of the Equator, 
fuppofe in 23 Degrees Latitude, will reach to 6 8 
Degrees North Latitude, which is to the Northward 
of the Orcades-, and almoft to the North Cape of 
Norway \ Or if we fuppofe the Trade-wind to the 
North of the Equator, to flow diredly North-eaft, 
as it is alfo faid to do, and to ftrike againft a Surface 
inclining from South eaft to North weft, which is 
pretty near the Bearing of the Ijlhmus that joins 
North and South America ; in both thefe Cafes the 
Reflexion will be towards the North-caff. 
But there is no depending on this way of calcu- 
lating : Not that God does not ad according to the 
exadeft Rules of Geometry, in the Motion of the 
Winds, as well as in all other Parts of the Creation : 
But we do not know, at leaft I am far from pre- 
tending to know, all the infinite Variety of Rever- 
berations that the Wind muft have, from the uneven 
Surfaces it ftrikes againft, between Cape St. Augujlin 
and the Bottom of the Gulph of Mexico. I make 
no doubt but that different Parts of this Air are 
xefleded a Thoufand different Ways ; and yet that the
