Note 4 — Chapter XIX · ASCENT OF SIPAN
Reading edition
It would require a series of very careful observations to determine whether this eminence—which I shall call the eastern summit—or the western summit of Sipan be the higher. By boiling-point we obtained the following results:—Eastern summit (4th August), 13,590 feet; western summit (5th August), 13,714 feet. But these readings were taken on different days. On the other hand, the aneroid registered:—Eastern summit (4th August), 13,650 feet; eastern summit (5th August), 13,790 feet; western summit (5th August), 13,754 feet. At present the question must be left open—and indeed it is not of much importance. ↑
