Note 45 — Appendix.

In the Ninth Bridgewater Treatise, Mr. Babbage has employed various arguments deduced from the Analytical-Engine, which afford some idea of its powers. See second edition. In 1838, several copies of plans of this new engine, engraved on wood, were circulated amongst Mr. Babbage’s friends at the Meeting of the British Association at Newcastle.

In 1840, Mr. Babbage had one of his general plans of the Analytical-Engine lithographed at Paris.
