In the first volume of my “Attempt to establish the First Principles of Chemistry by Experiment,” p. 442, I give the analysis of the sodium chloride of gold, and find the constituents to be

But I state at the same time, my uncertainty whether the gold in the salt was in the state of a chloride or muriate. This uncertainty raising a doubt, whether the peroxide of gold contained two or three atoms of oxygen, I thought it highly necessary to clear it up.
