Some of my friends went to the cave a few weeks after my visit, and found that the whole sheet had been pared off and carried away.

On some parts of the wall the sheet was not completely continuous, being formed of broad and distinct cascades, connected by cross channels of ice, and uniting at their upper and lower ends, thus presenting many curious and ornamental groupings.

On cutting through this ice, it was found not to lie closely on the rock, a small intermediate space being generally left, almost filled with minute limestone particles in a very wet state; and the whole cavern showed signs of more or less thaw.
[Illustration: THE GLACIERE OF S.GEORGES.VERTICAL SECTIONS OF THE GLACIERE OF S.GEORGES.] It was natural to examine the structure of the ice in this glaciere, after what we had observed on La Genolliere.

The same prismatic structure was universal in the sheet on the wall, and in the blocks which lay here and there on the floor and formed the sole remains of former columns.

It was to be observed also in many parts of the ice-floor itself.
