Whole afterwards unite, or the far greater Part, and 
flow this Way. I find myfelf under a Neceflity of 
fuppofing what I cannot demonftrate Mathematically, 
fince I can aflign no other Caufe why the South»weft 
Wind blows fo long with us. 
But there are fome other Fafts which flrongly flip- 
port my Hypothefis j viz. Currents of the Sea, and 
the Wind in the Atlantic Ocean, to the Northward 
of the Trade-wind. 
With regard to the Currents, ^Dumpier tells us, it 
is generally obferved by Seamen, that, in all Places 
where the Trade-wind blows, the Current moves the 
fame Way with the Wind; and that though it be 
perceived mold near the Shore, yet it makes no 
fenfible Riling in the Water, as the Tides do. He 
fays, there is always a ftrong Current fetting from 
Cape St .Auguftin Weft ward, occafioned, as he remarks, 
by the South-eaft Trade-wind driving the Surface 
flanting on the Coaft of Braftl ; which, being there 
flopped by the Land, bends its Courfe Northerly, 
towards Cape St. Auguftin ; and, after it has doubled 
that Promontory, it falls away towards the Weft- 
Indies , down along the Coaft Weft ward, till it 
comes to Cape Gratia de'Dios \ from thence North- 
weft towards Cape Catoch in Pfucatan , thence to the 
Northward between ‘Jucatan and Cuba. He fays, 
that in tl;e Chanel, between yucatan and Cuba , he 
has found the Currents extraordinary ftrong; that it 
is probable, that the Current which fets to Leeward, 
on all the Coaft from Cape St. Auguftin to Cape 
Catoch , never enters the Bay of Mexico , but bends 
Id ill to the Northward, till it is checked by the 
Florida Shore ; and then wheels about to the Eaft,
