Anotta, Arnotta, Annotto, Terra Or-Leana, Roucou, etc. are names of a vegetal substance brought from the West Indies, of an orange-red colour, soluble in water and spirit of wine, but very fugitive and changeable, and not fit for painting. It is principally used by the dyer, and in colouring cheese. It is also an ingredient in some lackers. See Carucru, Chap. XIX. Art. ii.
