good determination of the hours of maximum and minimum on mountains in 

 the temperate zone. Compare observations made in 1832, 1841, and 1842, 

 on the summit of the Faulhorn (Martins, Meteorologie, p. 254).

 phenomena systematically viewed, in a short memoir entitled " "Witterungs- 

 verhaltnisse von Berlin," 1842. Concerning the early knowledge of the 

 rotation of the winds possessed by navigators, compare Churruca, " Viage al 

 Magellanes," 1793, p. 15 ; and respecting a remarkable expression made use 

 of by Columbus, and preserved by his son Don Fernando Colon in the " Vida 

 del Almirante," cap. 55, see Humboldt's Examen critique de 1'hist. de la 

 Geographic, T. iv. p. 253. 



(S 89 ) p. 311. " Monsun," (in Malay, musim, the hippalus of the Greeks), 

 is derived from the Arabic word " mausim" fixed time or epoch, season, 

 time of the assembling of the pilgrims at Mecca. The word has been trans- 

 ferred to the season of the regular or periodical winds, which are named from 

 the countries from whence they blow, as " the Mausim of Aden," " of 

 Guzerat," " of Malabar," &c. (Lassen, Indische Alterthumskunde, Bd. i. 1843, 

 S. 211). On the different relations which prevail where the atmosphere has 

 a solid and where it has a liquid base (land and sea), see Dove, in the Abhandl.
