Fig. 6: A modification of Volta’s column battery
“Take a tube of glass open at its two extremities: shut one of them with a stopper of copper, terminated below by a stick of the same metal, which is prolonged between, as is represented in fig. 6, and fill this tube with any of the liquids above mentioned, with water, for example, with saline solutions, or even with an acid; we shall then have an arrangement exactly similar to that of the plates of zinc and of copper soldered end to end. But the electromotive property will be incomparably weaker” (p. 431).
