c. 1901, The Living Races of Mankind, New York: C.L. Bowman & Co., Volume 1, Chapter 8, part 3, p. 215, I may remind the reader that if Southern Tibet were at a lower elevation its climate would be hot, the latitude of Lhassa being given as practically the same (if anything slightly south) as that of Cairo. So that the intense cold is merely produced by the elevation, and the heat of the sun’s rays is intensified by the great clearness of the rarefied air; hence the great disbalances in the temperature, which make the problem of dressing a difficult one.
