from September till April ; aftd from April till Sep- 

 tember from the S. W. This variable wind or mon- 

 soon, like the others on this coast, extends but for 

 a very fhort way from the fliore, and is evidently 

 occasioned by the same causes as the other periodical 

 winds. For during the summer, which in this cli- 

 mate is between September and April, the land of the 

 •continent being heated by the sun, draws the trade- 

 wind from its common course of S. E. a little t?> 

 the westward; and as the coast here bends towards 

 the S. W. the wind in some measure (as it always 

 does) follows the same direction, and produces this 

 E. N, E. monsoon. But in the winter, when this re- 

 gion becomes more cool, the east wind is repelled 

 by the dense cold air ft-om the mountains j by which 

 means it is bent to tJie northward, and is forced a- 

 long the coast to Cape St Augustine; where,, meet- 

 ing with no farther hinderauce, it again falla in witk 

 the general trade-wind, and is carried along with it ia 

 its proper direction. 



Winds on the coast of Chili and Peru^ 

 We have purposely omitted mentioning the winds 

 on the west coasts of Africa and America, till the 

 others were explained, as the causes of the peculiari-^ 

 ties here observed will be now more easily compre- 

 hended. On the coasts of Chili and Peru, in Ameri- 

 ca, from 25'. or 30". of south latitude to the line j 

 and on the parallel coast of Angola^ XSc^ \i\ Africa, 

 the windblows all the year from, the south, varying in 

 its direction a little in different places, according ta 

 the direction of tlie coast, towards which it always ia-
