Note 21 — Chapter XX · MOUNT EVEREST

By means of theodolite observations made from a single point near the Base Camp, this height has worked out at 27,235 feet. This latter height is calculated on the assumption that the altitude of Mount Everest is 29,002 feet. It may be of interest to note, however, that the mean of numerous observations made by the Survey of India from twelve different stations places the height of Everest at 29,141 feet. This figure has not yet been finally corrected for deviation of gravity. When due allowance for this has been made the height of Mount Everest will probably be found to be about 29,200 feet. In the same way the point reached by Geoffrey Bruce and myself works out at (27,235 + 198) = 27,433 feet; a height that is exceeded, as far as I know, by four mountains, all in the Himalayas; namely, Mount Everest, K2 (28,250 ft.), Kanchenjunga (28,150 ft.) and Makalu (27,790 ft.).
