No one would have believed in the last years of the nine- teenth century that this world was being watched keenly and closely by intelligences greater than man’s and yet as mor- tal as his own; that as men busied themselves about their vari- ous concerns they were scrutinised and studied, perhaps al- most as narrowly as a man with a microscope might scrutinise the transient creatures that swarm and multiply in a drop of water. With infinite complacency men went to and fro over this globe about their little affairs, serene in their assurance of their empire over matter. It is possible that the infusoria under the microscope do the same. No one gave a thought to the older worlds of space as sources of human danger, or thought of them only to dismiss the idea of life upon them as impossible or improbable.
