of Victor Jacquemont, who fell an early sacrifice to his noble and unwearied ardor. (See his 'Correspondance pendant son Voyage dans l'Inde', 1828 'a' 1832, liv. 23, p. 290, 296, 299.) "Perpetual snow," says Jacquemont, "descends lower on the southern than on the northern slopes of the Himalaya, and the limit constantly rises as we advance to the north of the chain bordering on India. On the Kionbrong, about 18,317 feet in elevation, according to Captain Gerard, I was still considerably below the limit of perpetual snow which I believe to be 19,690 feet in this part of Hindostan." (This estimate I consider much too high.) [Footnote continues] The same traveler says, "To whatever height we rise on the southern declivity of the Himalaya, the climate retains the same character, and the same division of the seasons as in the plains of India; the summer solstice being every year marked by the same prevalence of rain which continues to fall without intermission until the autumnal equinox. But a new, a totally different climate begins at Kashmir, whose elevation I estimate to be 5350 feet, nearly equal to that of the cities of Mexico and Popayan" ('Correspond. de Jacquemont', t. ii., p. 58 et 74). The warm and humid air of the sea, as Leopold von Buch well observes, is carried by the monsoons across the plains of India to the skirts of the Himalaya which arrest its course, and hinder it from diverging to the Thibetian districts of Ladak and Lassa. Carl von Hugel estimates the elevation of the Valley of Kashmir above the level of the sea at 5818 feet, and bases his observation on the determination of the boiling point of water (see theil 11, s. 155, and 'Journal of Geog. Soc.', vol. vi., p. 215). In this valley, where the atmosphere is scarcely ever agitated by storms, and in 34 degrees 7 minutes lat., snow is found, several feet in thickness, from December to March.
