2. Extract from a letter fromBaron Humboldt, dated Berlin,
January 10, 1838. “I must be permitted to offer my
sincere congra-tulations to the Geographical Society, at havingfound so excellent a traveller in Mr. Schomburgk,uniting so
much courage with so much devotedness.His latest labours in Guayana, the
ascent of the riversBerbice and Corentyn, place him very high in my
esti-mation; and the zone of hieroglyphic figures, sculp-tured in the rock, from Encamarada, in 66 deg. 50min. West, to the
Eastern houndary of BritishGuayana, a distance of nearly 600 geographical
miles,

|Spaltenumbruch| is an ethnographical fact, which daily increases ininterest. I am
much pleased to see the notice takenin your journal of the work of my
friend and com-panion, M. Gustave Rose. Should I yet publish thedetail of my own astronomical observations in Sibe-ria, it
will only be in order to fix more accuratelythe points where I have made
observations for ter-restrial magnetism. I bespeak the same indulgencefor these labours in Asia, that has formerly beenshown to my
travels in America. The admirabletrigonometric levelling between the Black
Sea andthe Caspian is at length finished. There is depres-sion, but a much less depression than M. Parrot an-nounced after his first
barometric levelling by sta-tions. This always appeared to me probable on
ac-count of the elevation of Kasan, and on account ofsome
corresponding observations that I obtainedduring my journey to the Caspian.
The levelling ofM.M. G. Fuss, Sabler, and Savitch, shows that thelevel of the Caspian is about 105 feet lower than thatof the
Black Sea.—
