A considerable number of ice-islands, as opposed to icebergs, were observed 

 off King Edward's Land. Varying in extent from half a mile to a mile or more 

 across, they had all the same low, perpendicular sides, and a surface gradually 

 rising to a rounded summit 200 or 300 feet above the sea, quite distinct from the 

 flat top of an iceberg. Soundings taken round them proved them to be aground, 

 and it is evident that no great length of time had elapsed since they formed a 

 continuous part of the main ice -sheet, from which they are now separated by a 

 channel of open water. They are, in fact, detached remnants of that ice-sheet, 

 persisting only because they are bottomed upon shoals ; and their disappearance, 

 now that they are isolated, can be but a matter of a few years.
