B. FOR THE HIMALAYA.
5. Falut— Daejiling, from Hermann's observations taken from Mav 26 to June 10,
1855, during the height of the rainy season. By trigonometric measurement, the
barometer was found to be put up 204 feet below the summit of Falut, for which
we adopt the value of the Gr. T. S. = 12,042 feet. The cistern of the barometer was
therefore 11,838 feet above the level of the sea.
6. Leh—'Massuri, and Leh — Simla, for three months, July, August, and Sep-
tember, 1856, from observations by Hermann, Robert, and Harkishen.
The curves, on the same scale for the vertical co-ordinates as those of the yearly
period, (see p. 52) are collected in plate No. 2, and represent the entire daily period.
