the surface of the globe sea, the winds would be constant* 

 and blow in one direction : various circumstances break its 

 current, and drive it back against its general course, forcing 

 it upon coasts that face the west : want of a true system of 

 trade-winds supplied by an imperfect history of them : north 

 wind prevails during October, November, December, and 

 January, in the Atlantic, under the temperate zone : north 

 wind reigns during the winter of Nova Zembla, and other 

 arctic countries : south wind prevails during July in the 

 Cape de Verde Islands : north-west wind blows during 

 September at the Cape of Good Hope : regular winds pro- 

 duced by various causes upon land : ancient Greeks first 

 observed them : in general, wherever a strong current of 

 water, there is a wind to attend it : regular wind produced 

 by the flux and reflux of the sea : winds called monsoons : 

 some peculiar to certain coasts : south wind constant upon 

 those of Chili and Peru : other winds particular to various 

 coasts, i. 293. 



Winds (at land) puff by intervals, and why; not so at sea; 

 east wind more constant than any other, and generally most 

 powerful ; wind blowing one way, and clouds moving ano- 

 ther, forerunners of thunder ; cause of this surprising ap- 

 pearance remains a secret ; from sea, generally moister than 

 those over tracts of land ; more boisterous in spring and 

 autumn than at other seasons ; their force does not depend 

 upon velocity alone, but also upon density ; reflected from 

 sides of mountains and towers, often more powerful than 

 in direct progression ; raise sandy deserts in one country, 

 to deposit them upon some other ; south winds in summer 

 so hot in Egypt as almost to stop respiration, and produce 

 epidemic disorders, continuing for any length of time ; 

 deadly along the coasts of the Persian Gulf, and of India; 

 assume a visible form, i. 300. 



Windpipe, in men, has a lump not seen in women, i. 429. 

 Makes convolutions within a bird, and is called the laby- 

 rinth ; this difference obtains in birds seemingly of the same 

 species, iv. 11. Strange in the throat of the crane, 302. 



Wings (of birds) answer to the fore-legs of quadrupeds ; their 

 description ; bastard wing, iv. 6. Flap of a swan's wing 

 breaks a man's leg ; a similar blow from an eagle lays a man 

 dead instantly, 7. Of butterflies, distinguish them from 

 flies of other kinds ; their number and beautiful colours,

Winter, beginning round the poles, the misty appearance of 

 heat in southern climates is there produced by cold, i. 328. 



Wististi, a monkey of the sagoin kind, remarkable for the 

 tufts of hair upon its face, and its annulated tail, iii. 319.
