SECT xxxI--_Observations upon Pyro-mucous Acid, and its Combinations_

This acid is obtained by distillation in a naked fire froar, and all the saccharine bodies; and, as these substances swell greatly in the fire, it is necessary to leave seven-eighths of the retort e to red, and leaves a st with the epidermis It may be procured less coloured, by means of a second distillation, and is concentrated by freezing, as is directed for the citric acid It is chiefly coenated, and is convertible into oxalic and enation with the nitric acid

It has been pretended that a large quantity of gas is disengaged during the distillation of this acid, which is not the case if it be conducted slowly, by means of moderate heat
