INTRODUCTION'. 29 



not have attained to the height of that great Colossus of the 

 Andes, the Chimborazo, whose height is twice that of Mount 

 JEina.', and we must pile the Kighi, or Mount Athos, on the 

 summit of the Chimborazo, in order to form a just estimate 

 of the elevation of the Dhawalagiri, the highest point of the 

 Himalaya. But although the mountains of India greatly sur- 

 pass the Cordilleras of South America by their astonishing el- 

 evation (which, after being long contested, has at last been 

 confirmed by accurate measurements), they can not, from their 

 geographical position, present the same inexhaustible variety 

 of phenomena by which the latter are characterized. The 

 impression produced by the grander aspects of nature does not 

 depend exclusively on height. The chain of the Himalaya is 

 placed far beyond the limits of the torrid zone, and scarcely is 

 a solitaiy palm-tree to be found in the beautiful valleys of 

 Kumaoun and Garhwal.* On the southern slope of the an- 

 cient Paropamisus, in the latitudes of 28^ and 34^, nature no 

 longer displays the same abundance of tree-ferns and arbores- 

 cent grasses, hehconias and orchideous plants, which in tropic- 



Thus Mont Blanc is 5646 feet below Clihnborazo; Cbimborazo, 3770 

 feet below the Sorata ; the Sorata, 549 feet below the Jawahir, and prob 

 ably about 2880 feet below the Dhawalagiri. According to a new 

 measurement of the Illimani, by Penlland, in 1838, the elevation of this 

 jnountain is given at 23,8G8 feet, varying only 133 feet from the meas 

 m-emeut taken in 18'27. The elevations have been given in this note 

 with minute exactness, as erroneous numbers have been introduceJ 

 into many maps and tables recently published, owing to incorrect re 

 ductions of the measurements. 



[In the preceding note, taken from those appended to the Inti'oduc- 

 tion in the French translation, rev/ritten by Humboldt himself, the 

 measurements are given in meters, but these have been converted into 

 Engbsh feet, for the greater convenience of the general reader.] — Tr. 



* The absence of palms and tree-ferns on the temperate slopes of tha 

 Himalaya is shown in Don's Flora Nepalensis, 1825i and in the remark- 

 able series of lithographs of Wallich's Flora Indica, whose catalogue 

 contains the enormous number of 7683 Himalaya species, almost all 

 phauei'ogamic plants, which have as yet been but imperfectly classified. 

 In Nepaul (lat. 261"^ to 27^^) there has hitherto been observed only oca 

 species of pabn, Chama^rops martiana, Walk {Plantce Asiat., lib. iii., p. 

 5, 211), which is found at the height of 5250 English feet above the leve 

 of the sea, in the shady valley of Bunipa. Th"e magnificent tree-fern 

 Alsophila bninoniana, Wall, (of which a stem 48 feet long has been iu 

 the possession of the British Museum since 1831), does not grow in Ne- 

 paul, but is found on the mountains of Silhet, to the northwest of Cal- 

 cutta, in lat. 24° 50'. The Nepaul fern, Paranema cyathoides, Don, 

 formerly known as Sphaeroptera barbata, Wall. {PlantcB Asiat., lib. i. 

 p. 42, 48). is, indeed, nearly related to Cyathea, a species of which I 

 have seen in the South American Missions of Caripe, measuring 33 feet 

 »i height; this is not, however, properly speaking, a tree.
