DAVY, HUMPHRY. - IMPROVING VOLTAIC PILES.

An Account of some Galvanic Combinations, formed by the Arrangements of single metallic Plates and Fluids, analogous to the new alvanic Apparatus of Mr. Volta. ead June 18, 1801.

(London, W. Bulmer and Co., 1801). 4to. No wrappers as extracted from "Philosophical Transactions" 1801 - Part II. Pp. 397-402. Clean and fine.

First appearance of an importent paper in which Davy's states, that the voltaic pile only works under certain conditions, and only when the conducting substance between the plates is capable of oxydating the zink. The principle discovered here guided Davy in designing new types of pile, with elements chosen from the whole variety of known metals.
