“Somerset House” [transverse section at top, longitudinal section on bottom]

The annexed plate represents two sections of our habitations during the winters of 1832-3; the upper or transverse section shows two persons sitting at a table in the shaded part, the divisions of which show the frame, first and second roof, and the bed cabins; the blue parts represent the ice which covered the house, the passage into it, and addition which was made to keep out the cold. The lower or longitudinal section, shows the men and officers sitting at their mess table, the fireplace, oven, and funnel, and part of the ice wall which formed an enclosure for exercise. The tube projecting through the roof is the valve to let off the foul air or vapour. [John Ross, p. *688.]
