Thomas, the wind is always S. or S. W. probably from an inclination of 

 the trade wind towards the land. 



9. Between lat. 4 and 10, and between the longitudes of Cape Yerd 

 and the Cape Verd Islands, there is a track of sea very liable to storms 

 of thunder and lightning-. It is called the rains. Probably there are op- 

 posite winds that meet here. 



10. In the Indian Ocean, between 10 and 20 S. hititude, the wind is 

 regularly S.E. From Jane to November, these winds reach to within 

 2 of the Equator : but from December to May the wind is N. W. between 

 lat. 3 and 10 near Madagascar, and from 2 to 12 near Sumatra. 



11. Between Sumatra and Africa, from 3 S. latitude to the coa=t* on 

 the N. the monsoons blow N.E. from September to April, and S. W. from 

 March to October: the wind is steadier, aud the weather fairer, in the 

 former half year. 



12. Between Madagascar and Africa, and thence northwards to the 

 Equator, from April to October there is a S.S.W. wind, which further 

 N. becomes W.S.W. 



13. East of Sumatra, and as far as Japan, the monsoons are N. aud S. 

 but not quite so certain as in the Arabian gulf. 



14. From New Guinea to Sumatra and Java, the monsoons are more 

 N.W. and S.E. being on the south of the Equator ; they begin a month or 

 six weeks later than in the Chinese seas. 



15. The changes of tliese winds are attended by calms and storms. 



III. Winds variable. 



In the temperate zones the direction of the winds is by no means so 

 regular as between the tropics. In the north temperate zone, however, 

 they blow most frequently from the S.W., in the south temperate zone, 

 from the N.W. ; but changing* frequently to all points of the compass, 

 and in the north temperate zones blowing, particularly during the 

 spring, from the north-east. 



From an average of 10 years of the register kept by order of the Royal 

 Society, it appears that at London the winds blow in the following 

 order : 



Winds, Days. Winds. Days. 



South-west ~~*~~, 112 South-east 32 



North-east ,~~~, 58 East ~~+~~* ~ , 26 



North-west ~~ 50 South ~~^,,,~ 18

It appears from the same register, that the S.W. wind blows at an 

 average more frequently than any other wind during every mouth of th<j
