There happened to be a still
higher summit (called the Gorner Grat), above the hotel,
and notwithstanding the fact that it overlooks a glacier
from a dizzy height, and that the ascent is difficult
and dangerous, I resolved to venture up there and boil
a thermometer. So I sent a strong party, with some
borrowed hoes, in charge of two chiefs of service, to dig
a stairway in the soil all the way up, and this I ascended,
roped to the guides. This breezy height was the summit
proper - so I accomplished even more than I had originally
purposed to do. This foolhardy exploit is recorded on
another stone monument.
I boiled my thermometer, and sure enough, this spot,
which purported to be two thousand feet higher than the
locality of the hotel, turned out to be nine thousand
feet LOWER. Thus the fact was clearly demonstrated that,
ABOVE A CERTAIN POINT, THE HIGHER A POINT SEEMS TO BE,
THE LOWER IT ACTUALLY IS. Our ascent itself was a
great achievement, but this contribution to science was
an inconceivably greater matter.
Cavilers object that water boils at a lower and lower
temperature the higher and higher you go, and hence the
apparent anomaly. I answer that I do not base my theory
upon what the boiling water does, but upon what a boiled
thermometer says.
