Kuen-lün by the Bolor, the corresponding direction of the axes of elevation (inclining from east to west in the Kuen-lün and Hindoo Cush, and on the other hand south-east and north-west in the Himalaya) proves, that the Hindoo Cush is a prolongation of the Kuen-lün, and not of the Himalaya which is associated to the latter in the manner of a gang or vein. The point where the Himalaya changes its direction, that is to say, where it leaves its former east-westerly direction, lies not far from 81° east long. The Djawahir is not, as has hitherto been supposed, the next in altitude to the Dhawalagiri, which is the highest summit of the Himalaya; for, according to Joseph Hooker, this rank is due to a mountain lying in the meridian of Sikhim between Butan and Nepaul, called the Kinchinjinga or Kintschin-Dschunga. This mountain (Kinchinjinga) measured by Col. Waugh, Director of the Trigonometrical Survey of India, has for its western summit an altitude of 28,178 feet, and for its eastern 27,826 feet, according to the _Journal of the Asiatic Soc. of Bengal_, November, 1848. The mountain, now considered higher than the Dhawalagiri, is represented in the engraving to the title-page of Joseph Hooker’s splendid work, _The Rhododendrons of Sikkim Himalaya_, 1849. Determination of the snow-limits on the northern and southern slopes of the Himalaya; the former lies in the mean about 3620 up to 4900 feet higher. New statements of Hodgson. But for the remarkable distribution of heat in the upper strata of the air, the table-land of western Thibet would be uninhabitable to millions of human beings—pp. 63–80. The Hiongnu, whom Deguignes and John Müller considered to be a tribe of Huns, appear rather to be one of the widely spread Turkish races of the Altai and Tangnu mountains. The Huns, whose name was known even to Dionysius Periegetes, and who are described by Ptolemy as Chuns (hence the later territorial name of Chunigard!) are a Finnish tribe, from the Ural mountains, which separate the two continents—pp. 80–81. Representations of the sun, animals, and characters, graven on rocks at Sierra Parime, as well as in North America, have frequently been regarded as writing—p. 82.

Orographic remarks on the two mountain clusters (Pacaraima and Sierra de Chiquitos) which separate the three plains of the lower Orinoco, the Amazon, and La Plata rivers from each other—p. 84.
