     {Hydrocyanic acid} (Chem.), a colorless, mobile, volatile
        liquid, {HCN}, having a characteristic peach-blossom odor.
        It is one of the most deadly poisons. It is made by the
        action of sulphuric acid on yellow prussiate of potassium
        (potassium ferrocyanide), and chemically resembles
        hydrochloric and hydrobromic acids. Called also {prussic
        acid}, {hydrogen cyanide}, etc.
