With this idea in mind, their scientists worked together and finally produced a body of metal, a body machine which was driven by atomic force, like all of their machines, and which needed only the slight, occasional care which is given to any machine. Inside that body had been arranged an electrical nerve-system, the controls of which led up into the square metal head. In that head, also, have been placed a small super-radio by which silent, constant communication could be had from metal body to metal body. Nerves, sense organs, muscle, they were all there, and all were artificial, in organic. The metal body lacked only a brain.

It was then that one of their scientists performed his greatest achievement, and brought success to their plan. From the living body of one of their number he removed the living brain, as their consummate art in Super-surgery enabled him to do. This living brain was then placed within a specially-prepared brain chamber of a metal body, inside its cubicle head.
