This is a sepia-toned photograph of a man standing next to a large, cylindrical metal condenser. The man, dressed in a long-sleeved shirt and trousers, is looking up at the top of the condenser. The condenser appears to be a repurposed piece of machinery, with various pipes and fittings attached to it. It is positioned on a wooden deck, surrounded by debris and scattered materials. In the background, there is a wooden building with a window visible. A funnel is placed on top of the condenser. The image is captioned: 'M. van Rysselberghe at the condenser, which was converted into a snow melter. This apparatus, by the combined ingenuity of van Rysselberghe and van Mirlo, was taken out of the engine-room, placed on deck, and so altered that it burned seal blubber. From this the Belgica was supplied with water.'
