After having the oxide well washed and boiled in nitric acid for a few minutes and exposed to a gentle heat for an hour, the nitrate was obtained from the oxide: a fluid of a golden colour, and of the consistency of syrup." Dilutions of this were made, and the 4th was proved for Hering by Dr. Pehrson, the 2nd and 3rd by Dr. Negendank.
