G marks the place of a free stalagmite of ice, formed under a
fissure in the roof; and each F represents a column from the roof, or
from a lateral fissure in the wall.
The most striking features of this cave were the three domes, marked H
in the ground-plan, in which they ought strictly not to appear, as being
confined to the roof: one of them is shown also in the vertical section
of the cave. They occur where the roof is from 3 to 4 feet above the
floor. It will be understood, that the bent attitude in which we were
obliged to investigate these parts of the cave was exceedingly
fatiguing, and we hailed with delight a sudden circular opening in the
roof which enabled us to stand upright. This delight was immensely
increased when our candles showed us that the walls of this vertical
opening were profusely decorated with the most lovely forms of ice. The
first that we came under passed up out of sight; and in this, two solid
cascades of ice hung down, high overhead, apparently broken off short,
or at any rate ending very abruptly: the others did not pass so far
into the roof, and formed domes of very regular shape.
