I might also add, as another argument against the probability ofice extending to abyssal depths, that pressure tends to liquefy ice,or, in other words, to lower the freezing-point of water, and iceat great depths is under great pressure. For example, ice at the 70 Prof. J. Milne—On the Flotation of Icebergs. depth of 2400 feet would be under a pressure of about 73 atmo-spheres.

The more probable form in which the generality of icebergsexist are those which have their limit represented by Case II.,where we have a series of stable forms, more or less conical in theirshape. Here the depth below the surface of the water neverexceeds the height which is above, but is pr
