This compmmd, which coixesponds to fhiosttl urio add, was discovered by does, and like this latter add is not known in the free state. Its potasdum salt is obtained when a solution of shiphtiious acid is mixed with one of potassium selenide, or when sdeninm is dissdved in a solution of ntnmal po ssium sulphite. The adenomljplkatea are isomorphous with the sulphates, and ate decomposed by all acids, even by snl utoos acH h the separation of red sdmuum. 

This compound was first observed by Sdieele in the dry distillation of uric aoH and by him called pyro-urio add. In the year 1827 SeruOas obtained the same acid by boiling tyanaric-cMoride with water thus —...
