ntaneous combustion over a glass-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 time to the free
air; it absorbs oxygen from the air, and becomes fully oxygenated.

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 small pieces of phosphorus through the tube, these are
dissolved with effervescence and red fumes of nitrous gas fly off; add
phosphorus so long 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.
