[Note A: The existence of metallic phosphites supposes that metals are susceptible of solution in phosphoric acid at different degrees of oxygenation, which is not yet ascertained--A]

[Note B: All the phosphites were unknown till lately, and consequently have not hitherto received nareater part of the phosphats were only discovered of late, and have not yet been named--A]

SECT XVI--_Observations upon Phosphorous and Phosphoric Acids, and their Combinations_

Under the article Phosphorus, Part II Sect X we have already given a history of the discovery of that singular substance, with soetable and ani this acid in a state of purity is by burning well purified phosphorus under bell-glasses,coen; so that 100 parts of phosphoric acid is composed of 28-1/2 parts of phosphorus united to 71-1/2 parts of oxygen

This acid reedily attract the lass over mercury

To obtain phosphorous acid, which is phosphorus less oxygenated than in the state of phosphoric acid, the phosphorus lass-funnel leading into a crystal phial; after a few days, the phosphorus is found oxygenated, and the phosphorous acid, in proportion as it forms, has attracted moisture from the air, and dropped into the phial The phosphorous acid is readily changed into phosphoric acid by exposure for a long tien froenated

As phosphorus has a sufficient affinity for oxygen to attract it from the nitric and muriatic acids, we may form phosphoric acid, by means of these acids, in a very simple and cheap manner Fill a tubulated receiver, half full of concentrated nitric acid, and heat it gently, then throw in sh the tube, these are dissolved with effervescence and red fu as it will dissolve, and then increase the fire under the retort to drive off the last particles of nitric acid; phosphoric acid, partly fluid and partly concrete, remains in the retort
