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
