Note 13 — The Story of the Companion of Sirius
Reading edition
My references to ‘perfect gas of the density of platinum’ and ‘material 2,000 times denser than platinum’ have often been run together by reporters into ‘perfect gas 2,000 times denser than platinum’. It is scarcely possible to calculate what is the condition of the material in the Companion of Sirius, but I do not expect it to be a perfect gas.
