Abstract
IN Belone belone, the garfish, the bones, scales and fin rays are of a bright green colour. The chemical nature of this well-known colouring matter has long remained unknown. It cannot be extracted from the tissues in which it occurs by any organic, or neutral, weak acid or alkaline inorganic solvent. But in stronger bases the green scales show a particularly clear transition to yellow, which can be turned back to green again in acids. In at least ten per cent alcoholic hydrochloric acid, the green colouring matter quickly becomes a blue-green in solution and can be separated with chloroform. It gives a clear Gmelin reaction and shows in its insolubility all the typical characteristics of biliverdin.
