Don Cosme Churruca, Magellanische Meerenge (mitgetheilt 

 von Hrn. v. Humboldt aus Apendice a la Relacion del Viage 

 al Magelhanes. Madrid 1793 p. 15). En el emisferio auslral el 

 curso de los vientos se hace por lo comun en un order inverso 

 del que siguen en el otro emisferio. Si sabe que en nuestras mares 

 giron los vientos del N al E, del E al S, del S al O y del O al 

 N, y en el parte austral el contrario dal N al O, dal O al S, dal 

 S al E, y del E al N. 



Horsburgh, südlicher atlantischer Ocean 38°Br. (Eastlndia Sai- 

 ling Directory vol. I. p. 67). Although here the westerly winds 

 prevail during most months of the year, they are often very un- 

 settled, completing a revolution round the horizon, coincident 

 with the course of the sun, every two, three or four days, with 

 intervenlng calms, particulary when the wind is in the south 

 west quarler. When cloudy weather accompanies these nor- 

 therly or north west winds, there is a risk of a sudden shift to 

 SW or S. 



Meer südlich von der Agulhas Bank, I, p. 91. Around the Cape 

 Bank, as in the open Sea far to the SW, SE and southward of 

 the Cape the winds in changing, follow the course of the sun, 

 seldom veering from N to Eastward etc. but mostly from NW 

 to W. SW and Southward. After blowing strong from NW 

 or W, if the wind veers to SW and Southward, it becomes 

 light, or Is succeded by a calm.- If a light breeze continue, It 

 veers to S.Eastward, where it may keep fixed for a considerable 

 time, but not above a day most probably, If it be the winter 

 season; from SE it veers to E and NE, then to NNE and N. 

 When the wind at SE or ESE shiftet to NE, the Dutch Com- 

 manders were directed by the Company to take in the mainsail, 

 for in this case they expected a hard gale at NW, and if llght- 

 ning was seen in that direction, they thought the gale would 

 commence In the sudden shIft or whirlwind.

 of Terra Australls the progress of the gales Is usually this : the
