A section from the eleventh chapter of the serial published in New Review (May 1895) was deleted from the book. It was drafted at the suggestion of Wells's editor, William Ernest Henley, who wanted Wells to "oblige your editor" by lengthening the text with, among other things, an illustration of "the ultimate degeneracy" of humanity. "There was a slight struggle," Wells later recalled, "between the writer and W. E. Henley who wanted, he said, to put a little 'writing' into the tale. But the writer was in reaction from that sort of thing, the Henley interpolations were cut out again, and he had his own way with his text." This portion of the story was published elsewhere as "The Grey Man". The deleted text was also published by Forrest J Ackerman in an issue of the American edition of Perry Rhodan.
The deleted text recounts an incident immediately after the Traveller's escape from the Morlocks. He finds himself in the distant future of an unrecognisable Earth, populated with furry, hopping herbivores resembling kangaroos. He stuns or kills one with a rock, and upon closer examination realises they are probably the descendants of humans / Eloi / Morlocks. A gigantic, centipede-like arthropod approaches and the Traveller flees into the next day, finding that the creature has apparently eaten the tiny humanoid. The Dover Press and Easton Press editions of the novella restore this deleted segment.
