Note 72 — Chapter III · THE STEAM ENGINE
Reading edition
This project, however, is mentioned of an engine called by him “a semi-omnipotent engine,” the subject of the 98th invention: “an engine so contrived, that working the Primum mobile forward or backward, upward or downward, circularly or cornerwise, to and fro, straight, upright or downright, yet the pretended operation continueth and advanceth, none of the motions above-mentioned hindering, much less stopping the other.”
This engine is obviously not the same as that described as the sixty-eighth invention.
