from their route. On their side, the western shores of Mexico present 

 a similar alternation of winds, those from the south-west coming 

 in summer, and those from the north-east in winter. On coasts 

 parallel or merely oblique to the path of the trade-winds, a part of 

 these winds is not brought back, as in the West Indies or at Guinea, 

 but it is more or less attracted by the centre of heat, which lies out 

 of its regular course. It is thus that on the coast of Morocco, and 

 near the Archipelago of the Canary Islands, the wind from the north- 

 east is subject to a considerable deviation towards the African conti- 

 nent, and is sometimes transformed into a wind from the north. In 

 the same way the plateaux of New Granada and the llanos of Vene- 

 zuela turn aside the normal current which penetrates into the sea of the 

 Antilles, and oblige it to blow perpendicularly to the coast. Thus a 

 periodical breeze {los hrisotes) is produced, which may be considered 

 as an intermediate wind between the monsoon and the trade- wind 

 properly so-called.
