Zusammenfassung:THE most striking characteristic of the collection of lignin ‘structures’ listed by Brauns 1 is the extent of their dissimilarity. This state of affairs arises from the lack of an established criterion of purity for lignin. Purification of lignin preparations has usually been carried out according to the choice of the worker, and structural investigation undertaken without any proof of purity. Brauns's 1 admirable survey on the isolation of lignin should convince any interested reader of these facts.
