Jinks they regard as one of the lower animals, with a slight glimmering of reason ; and are so disgusted with his misuse of that reason that they decide he should be put out of the way. There is great verve and imagination in the story ; but Mr. Ridley is not wholly convincing in his science. It seems stRinge, for example, that Jinks should be in many ways better adapted for life on Mars than the inhabitants them- selves. Owing to the red glare of the atmosphere, for instance, the eyes of the Martian animals are of no use during the daytime. It seems something of a blunder-in the process
