Something from Mercury. John Russell Fearn

It came originally from the merciless, frost-bound wilderness of the night side of Mercury, the hellish planet nearest to the Sun. But when space explorer Harry Dagenham brings a long-dead, petrified snake–or something–back to Earth from Mercury, he discovers–quite suddenly–that the rock-hard creature is not quite so inert as it first appears! Here are six extraordinary stories from the golden age of the pulps: «Something from Mercury,» «The World That Dissolved,» «Pre-Natal,» «Beyond Zero,» «Across the Ages,» and «Twilight Planet.» Great science-fiction adventure from the pulp magazine era!
