Boyle's Fuming Liquor is the term applied to a solution of sulphide of ammonium obtained by distilling a mixture of slaked lime, sal-ammoniac, and sulphur. The same substance is produced by passing sulphuretted hydrogen into a solution of ammonia. It is a straw-coloured liquid, possessing the odour of rotten eggs, and liberating sulphuretted hydrogen on addition of an acid or exposure to the air.
