MATERIAL The collection upon which this report is based is a small part of that made by the 'Discovery II' during her second commission, 1931-3. The stations made during that time are shown in Eigs. 1-3. They include two sets of closely placed stations in the Ealkland sector of the Antarctic, one made in each of the summer seasons 1931-2 and 1932-3 (Figs, i and 2).

The southernmost stations were along the edge of the pack-ice.
