The greatest length of the cave we found to be 112 ft.

7 in., and its breadth 94 ft., the general shape of the field of ice, which filled it to its utmost edges, being elliptical.

The surface was unpleasantly wet, chiefly in the line of the currents, which were now seen to pass backwards and forwards between the pits A and C.
In the neighbourhood of the pit B the water stood in a very thin sheet on the ice, which there was level, and rendered the style of locomotion necessitated by the near approach of the roof extremely disagreeable, as I was obliged to lie on my face, and push myself along the wet and slippery ice, to explore that corner of the cave, being at length stopped by want of sufficient height for even that method of progression.
The circle marked D represents a column from the roof, at the foot of which we found a small grotto in the ice, which I entered to a depth of 6 feet, the surface of the field of ice showing a very gracefully rounded fall at the edges of the grotto.

At the point E there was a beautiful collection of fretted columns, white and hard as porcelain, arranged in a semicircle, with the diameter facing the cave, measuring 22 ft.
