(15/4.

This structure in frozen snow was long since observed by Scoresby in the icebergs near Spitzbergen, and, lately, with more care, by Colonel Jackson "Journal of Geographical Society" volume 5 page 12, on the Neva.
Mr.Lyell "Principles" volume 4 page 360, has compared the fissures, by which the columnar structure seems to be determined, to the joints that traverse nearly all rocks, but which are best seen in the non-stratified masses.

I may observe that in the case of the frozen snow the columnar structure must be owing to a "metamorphic" action, and not to a process during DEPOSITION.) On one of these columns of ice a frozen horse was sticking as on a pedestal, but with its hind legs straight up in the air.

The animal, I suppose, must have fallen with its head downward into a hole, when the snow was continuous, and afterwards the surrounding parts must have been removed by the thaw.
When nearly on the crest of the Portillo, we were enveloped in a falling cloud of minute frozen spicula.

This was very unfortunate, as it continued the whole day, and quite intercepted our view.
