DAVY, HUMPHRY. - ELECTROCHEMISTRY DISCLOSING THE NATURE OF SUBSTANCES.

The Bakerian Lecture. An Account of some new analytical Researches on the Nature of certain Bodies, particularly the Alkalies, Phosphorus, Sulphur, Carbonaceous Matter, and the Acids hitherto undecompounded; with some general Observations on Chemical Theory. Read December 15, 1808.

(London, W. Bulmer and Co., 1809). 4to. No wrappers as extracted from "Philosophical Transactions" 1809 - Part I. Pp. 39-104 and 1 engraved plate showing some of the apparatus used in his electrochemical researches. Fine and clean.

First printing of a historical paper in chemistry, in which Davy announced his isolation, by electrochemistry, of Calcium, Barium, Strontium and Magnesium, and claiming that boracic acid is metallic in nature and proposing the name "boracium". He further discusses chemical theory.

"The objects which principally occupied Mr. Davy's attention in the present lecture are, the elements of ammonia; the nature of sulphur; the nature of phosphorus, the states of carbonaceous principle in plumbago, charcoal, and diamond; the analysis of boracic acid; the analysis of fluoric acid; with a series of numerous experiments on muriatic acid."
