Here again, E. is predominant, as half the high winds come from this quarter. W. and N.W. together have only 6 per cent.
The total number of high winds is 51, or 5.6 per cent. of the total of wind observations.
The most frequent directions of storms are also E. and N.E.
The Aurora Australis.
During the winter months auroral displays were frequently seen — altogether on sixty-five days in six months, or an average of every third day — but for want of apparatus no exhaustive observations could be attempted. The records are confined to brief notes of the position of the aurora at the times of the three daily observations.
The frequency of the different directions, reckoned in percentages of the total number of directions given, as for the wind, will be found in the following table:

N. and N.E. are the most frequent, and together make up one-third of all the directions recorded; but the nearest points on either side of this maximum — E. and N.W. — are also very frequent, so that these four points together — N.W., N., N.E., E. — have 64 per cent. of the whole. The rarest direction is S.W., with only 3 per cent. (From the position of the Magnetic Pole in relation to Framheim, one would rather have expected E. to be the most frequent, and W. the rarest, direction.) Probably the material before us is somewhat scanty for establishing these directions.

CHAPTER III
Geology
Provisional Remarks on the Examination of the Geological
Specimens
Brought by Roald Amundsen’s South Polar Expedition
from the Antarctic
Continent (South Victoria Land and King Edward VII.
Land). By
J. Schetelig, Secretary of the Mineralogical Institute
of Christiania
University
The collection of specimens of rocks brought back by Mr. Roald Amundsen from his South Polar expedition has been sent by him to the Mineralogical Institute of the University, the Director of which, Professor W. C. Brogger, has been good enough to entrust to me the work of examining this rare and valuable material, which gives us information of the structure of hitherto untrodden regions.
