Continuation of Thomas Henry's 1795 paper on the chemistry of dyeing, covering the preparation of silk, cotton and linen before dyeing. It describes degumming silk with soap or alkaline solutions and sulphur bleaching, and alkaline boiling, souring and bleaching of cotton and linen. It then classifies colouring substances into three groups by how they attach to cloth, and discusses phlogiston versus antiphlogistian explanations of colour. The second part begins the discussion of mordants, which Henry proposes to call bases, naming alum and tin solutions as the principal white bases; it ends with "to be continued."
