| X4681 Hs {Lord Ernest Hives - Chair} /Mr.Robotham. H14/EA3.4.28. Laboratory. Re "Kleenwell" Salts. Our analysis figures for the above show it to consist of 90% Caustic Soda and 10% Potassium Cyanide. These figures are only approximate since the cyanide powder occurs in coagulated lumps, but we understand that a solution made up to the above strength has proved quite satisfactory. H1. He | ||
