Note 88 — ARCHIL.
William Johnston translation
[According to Dr. Ure, the Dutch first reduce the lichen to a fine powder by means of a mill, then mix a certain proportion of potash with it. The mixture is watered with urine and allowed to undergo a species of fermentation. When this has arrived at a certain degree, carbonate of lime in powder is added to give consistence and weight to the paste, which is afterwards reduced into small parallelopipeds, which are carefully dried.]
