Note 4 — ANNO DOMINI 2071. (continued 2)

Galvani was a professor of anatomy in the university of Bologna. While engaged in his anatomical investigations he observed, accidently so to say, that when the lumbar nerves of a dead frog were connected with the crural muscles by a metallic circuit, the latter became briskly contracted. The electricity theory drawn by Galvani from his observation of the frog was chiefly opposed by the philosopher likewise here mentioned, Alexander Volta, professor of physics in Pavia.
