felow conftantly from the faaie point, nor diredly from 
the Eaft; but for the one half of the year, to wit from 
^pril to November ov thereabouts, they come from the 
South-Eaft, and for the other half of the year, t'/;^. from 
November to Jpril , they blow from the North-Eafl:. 
And thele I fuppofe they call their Monfons and trade 
winds. Hence it is that they who fail from China, Ja- 
pan, 6cc. to Bantam muft wait the Northerly Monlon 
which falls between November and Jpril j and they who 
return from Bantam muft go back again when the Sou- 
therly Monfon comes, which is between ^r// and iVi?- 
vember. And the Currents of the Seas are faid toob- 
ferve the lame motion, and changes with the winds. I 
know norwhether thefe Monfons do blow exactly from 
the fame points in all parts, for it is like where there 
are Bays , highlands and IJlands , Sec, the Monfons may 
blow from different points; but this is cheifly to be under- 
ftoodof open Seas. 
I Now thefe Monfons I think may be eafily accounted 
I fol' from what has alreadie been faid auentr the caufe 
af the continual Eafterly winds between th.Q Tropicus ^ 
I for feeing the leiTening of the Jirs prefTure under the 
Line, and the preflureof the Neighbouring parts of the 
^tmofphere thereupon occafion thefe continual Brifes, if 
the Sun were conflantly in the jEquinoUial Line, it is like 
the wind would blow Hill dire(5Hy from the Eafl, but in 
that he is the one half of the year on the one fide of the 
Line and the other half on the other, there mufl: of ne- 
ceffity follow a change of thefe Brijes into ftated Mon- 
fons. For imagine the Atmofphere to be d'ivided into 
two equal Hemtfpheres by the jEquinoclial Plane, if the 
Sun were alwiays in the Flane, there would be fliil an e- 
qual prefTure from both thefe upon the Air 
under the Line and the Brife fhould be diredly from the 
Eafl. But now when the Sun comes on the North fide 
of the Line as far as t\icTropic\oi Cancer and back a- 
If C c G gain.
