1) The writer's observations plainly show that alkali metal compounds are externally photoelectrically active as against other authors' reports to the present time. 2) Potassium bromide clearly shows external photoelectric effect even by the visible rays longer than 5600Å; potassium chloride, sodium chloride, potassium cyanide, sodium ferrocyanide, sodium bromide and sodium sulphate by ultraviolet rays longer than 3150Å; potassium iodide, potassium ferrocyanide, ammonium chloride and sodium carbonate by ultraviolet rays longer than 2500Å; kalium oxalicum neutrale by visible rays longer than 4300Å; and sodium hydroxide, natriokalium tartaricum, sodium hyposulphite, potassium carbonate, potassium nitrate, sodium citrate, sodium phosphate, potassium sulphate, anhydrous iodic acid and potassium bichromate by ultraviolet rays longer than 2000Å. 3) The threshold wave lengths of halogen compounds and cyanide are relatively long amongst alkali metal compounds. 4) The photoelectric effect of potassium carbonate is very much weaker than that of other alkali metal compounds. 5) Thoroughly dry potassium nitrate is also photoelectrically active no less so than when it is slightly wet.
