whereby fo much of the Mbtion as was loft, is 

 again reftored , and thus the Wefterly Wind is 

 made perpetual. 



From the lame Principle it follows, that this 

 Eafterly Wind fhould on the North fide of the 

 /Equator, be to the Northwards of the Eaft, and 

 in South Latitudes to the Southwards thereof, 

 for near the Line, the Air is much more rarified, 

 than at a greater diftance from it ; becaufe of 

 the Sun twice in a Year Vertical, and at no 

 time diftant above 23 Degr. and a half ; at which 

 diftance the Heat, being as the Sine of the An- 

 gle of Incidence, is but little fhort of that of 

 the perpendicular Ray, Whereas under the 

 Tropicks, though the Sun ftay long Vertical, 

 yet he is as long 47 Degr. oft ; which is a kind 

 of Winter, wherein the Air fo cools, as that the 

 Summer-heat cannot warm it to the fame de- 

 gree with that under the ^Equator. Wherefore 

 the Air to the Northwards and Southwards, be- 

 ing lefs rarified than that in the middle, it fol- 

 lows, that from both fides it ought to tend to- 

 wards the ^Equator : This Motion compounded 

 with the former Eafterly Wind, anfwers all the 

 Phenomena of the general Trade-winds ; which, 

 if the whole Surface of the Globe were Sea 1 

 would undoubtedly blow all round the World, as 

 they are found to do in the Atlantkk. and J&thio- 

 iicli Oceans. 



But feeing that fo great Continents do inter- 

 pole, and break the continuity of the Oceans, 

 regard muft be had to the Nature of the Soil, 

 and the Pofirjon of the high Mountains, which 

 I foppofo the two principal Caules of the (eve- . 

 ral Variations of the Winds, from the former 

 general Rule ; For if a Country lying near the 

 Sun, prove to be flat, fandy, low Land, fuch
