SOME REMARKS TO THE HEIGHTS AND DISTANCES.
lake has a height of 4,968 m., and Camp CCCXIX at 1.s km. from the western shore = 5,002 m. On account of the altitudes I got for the camps situated east of the lake, we thought it necessary to make the altitude of the lake a few meters lower or 4,950 m. a height which, in the Meteorol. Journ., was also attributed to Camp CCCXIX. The 4,968 m. of the map is a misprint for 4,958 m. which was rounded to 4,960 Ill. in my text. In spite of the fact that Camp CCCXXIII, on the map, has 4,896 m., and thus becomes lower than the lake, although the ground rises from the lake to this camp, it is questionable whether it would not have been better not to alter the altitude of the lake at all, but to leave the result of the observations alone. The changing atmospheric pressure is the cause of the apparent anomalies which, as a rule, become visible along the lakes and river-courses. On the hypsometrical map which Colonel H. BYSTROM is now constructing in I : 200,000, the Shemen-Iso has 4,96o m., as in the present volume. According to the observations the height of four camps S. E. of Shemen-Iso are too low, viz. Camps CCCXXIII, CCCXXIII, CCCXXV and CCCXXVI. But in relation to one another, their heights may be fairly correct, except Camp CCCXXIV Still, they have been left unchanged in my text and in the Meteorol. Journ. Only at Camp CCCXXV//, 5,055 m., we are above the lake, in spite of the anomalies caused by the changes in the atmospheric pressure.
In the Meteorol. Journ., p. 36, Camp CXXV, Ye, has 3,988 m., and Camp CXXV I, Rung-ma 3,95o m. For these two places my map has 3,949 and 3,94o m. The first two are no doubt more correct if compared with the height at the river. On Pl. 8 of the map Camp CXXXIII has an altitude of 4,002 m. Perhaps, after all, the figures of the map are the most reliable.
The height at Lang-mar, Camp CXLIII, is found to be 4,33 I m., as entered on the map and in my text. In the Meteorol. Journal the height of the place has been altered by interpolation to 4,405 m. The first figure, 4,331, may, however, be the correct one.
On the map, Pl. 1o, the height of Camp CLXIX, Takbur, is 4,521 m. which in my text and in the Meteorol. Journ. has been changed into 4,532 m. on account of the fall of the river.
Diri-pu-gompa or Camp CCXXXI has on the map an altitude of 5,091 m., which has been corrected to 5,081 m. in the Meteorol. Journal.
The altitude 4,979 m. between Camp CCXLIV and Camp CCXL V entered both in my text, p. 383, and on the map, Pl. 13, is incorrect. In the Meteorol. Journal, p. 70, the correct figure, or 4,782 m., is to be found.
The altitude of 7ukli-hloyna-la is 5,825 m. both on the map, Pl. 13, and in my text. In the Meteorol. Journal it has been corrected to 5,821 m. The difference of 4 m. is of no consequence, 5,825 m. may be regarded as definite.
On Pl. 21 and in my text Camp CCCCX, Hlakelung-, has an altitude of 4,769 m. In the Meteorol. Journal this altitude has been altered to 4,744 m. So
