Points ; whilft the Southern part of that Ocean 

 follows the General Rule, and has perpetual Winds 

 about S, E ? J. Why in thefe General Trade- 

 Winds it fhould be always true, that to the 

 Northward of the /Equator it is inclin'd to the 

 Northwards of the Eaft ; and in South Latitudes, 

 to the Southward thereof ? 6. Why in thefe Seas 

 of China there {hould be fo great an Inclination 

 from the Eaft to the North, more than elfewhere ? 

 with many more, which it would be much eafier 

 to propofe than anfwer. 



But left I {hould feem to propofe to others, 

 Difficulties which I have not thought worth my 

 own Time and Pains, take here the refolt of an

 aforefaid Phenomena \ wherein if I am not able 

 to account for all Particulars, yet 'tis hoped the 

 Thoughts I have {pent thereon, will not be 

 judged wholly loft, by the Curious in Natural 

 Enquiries. 



Wind is moft properly defined to be the 

 Stream or Current of the Air, and where fach 

 a Current is perpetual and fixt in its Courfe, 'tis

 intermitting Caufe. Wherefore fome have been 

 inclin'd to propofe the diurnal Rotation of the 

 Earth upon its Axis, by which, as the Globe 

 turns Eaftwards, the loofe and fluid Particles of 

 the Air, being fo exceeding light as they be, 

 are left behind, fo that in refpecl: of the Earths 

 Surface they move Weftwards, and become a 

 conftant Eafterly Wind. This Opinion teems 

 confirm'd, for that thefe Winds are found only 

 near the /Equinoftial, in thofe Parallels of Lati- 

 tude where the diurnal Motion is iwifteft ; and
