SECT. XXXII.--_Observations upon Oxalic Acid, and its Combinations._

The oxalic acid is mostly prepared in Switzerland and Germany from the
expressed juice of sorrel, from which it cristallizes by being left long
at rest; in this state it is partly saturated with potash, forming a
true acidulous oxalat of potash, or salt with excess of acid. To obtain
it pure, it must be formed artificially by oxygenating sugar, which
seems to be the true oxalic radical. Upon one part of sugar pour six or
eight parts of nitric acid, and apply a gentle heat; a considerable
effervescence takes place, and a great quantity of nitrous gas is
disengaged; the nitric acid is decomposed, and its oxygen unites to the
sugar: By allowing the liquor to stand at rest, cristals of pure oxalic
acid are formed, which must be dried upon blotting paper, to separate
any remaining portions of nitric acid; and, to ensure the purity of the
acid, dissolve the cristals in distilled water, and cristallize them
afresh.
