Paper, 'Observations on pure ice and snow' by Thomas Andrews

Description

Andrews writes: 'The recent very severe winter afforded favourable opportunity and material for investigating some of the properties of ice and snow. The object of the following observations was to obtain information on the relative conductivity of ice and snow, the dilatation of pure ice, and its relative hardness or penetrability at various temperatures.' He goes on to describe a series of experiments and their results, finding that 'The relative conductivity of the ice was [...] about 122 percent greater than the snow under the conditions of experimentation.'
