the Wefterly Winds near the Coaft of Guinea i 

 and the Periodical Wefterly Monfoons under the 

 J&quator in the Indian Seas, did not declare the 

 infuffiency of that Hypothecs. Befides the Air be- 

 ing kept to the Earth by the Principle of Gra- 

 vity, would acquire the fame degree of Velocity 

 that the Earths Surface moves with, as well in 

 refpect of the diurnal Rotation* as of the Annu- 

 al about the Sun, which is about thirty times 

 fwifter. 



It remains theiefore to fubftitute fbme other 

 Caufe, capable of producing a like conftant Ef- 

 fect, not liable to the fame Objections, but a- 

 greeable to the known Properties of the Elements 

 of Air and Water, and the Laws of the Mo- 

 tion of fluid Bodies. Such an one is, I conceive, 

 the Action of the Sun Beams upon the Air and 

 Water, as he pafTes every Day over the Oceans, 

 confider'd together with the Nature of the Soil, 

 and Situation of the adjoining Continents : I 

 fay therefore, firft, rhat according to the Laws 

 of Statical the Air which is lefs rarified or 

 expanded by heat, and confequently more pon- 

 derous, muft have a Motion towards thofe 

 parts thereof, which are more rarified, and lefs 

 ponderous, to bring it to an ALquilibrium ; and 

 iccondly, That the Pretence of the Sun conti- 

 nually fiiifting to the Weftwards, that part to- 

 wards which the Air tends, by reafon of the 

 Rarefaction made by bis greater!: Meridian Heat, 

 Is with him carried Weftward, and confequently 

 the tendency of the whole Body of the lower 

 Air is that way. 



Thus a general Eafterly }Nind is formed, 

 which being impreffed upon all the Air of a vaft 

 Ocean, the Parts impel one the other, and fo 

 keep moving till the next return of the Sun,
