‎First appearance of a classic paper on Iodine. Iodine was discovered in 1811 by the French chemist Curtois and the proof of its elementary nature was given independently by Davy and Gay-Lussac.In the offered paper Davy ""describes Iodine monochloride (chlorionic acid), composed of 'one portion of iodine, and one of chlorine', and bright yellow trichloride...Davy also rediscovered phosphonium iodide as a sublimate of white cubic crystals by the action of iodine on phosphorus in presence of a little water, but thought they were a compound of hydroidic acid and phosphorus...(Partington IV, p. 89).‎
