(Nat. size.) solution of the gelatinising substance immediately begins; it is therefore essential, if an undue loss is to be avoided, for this preliminary washing to be carried out as rapidly as possible. After rinsing, the plants were squeezed free from excess of water, spread on clean paper and allowed to dry at room temperature and finally in the steam oven. To prepare the water-soluble gelatinising material two methods of extraction were employed: 1 See The Textile Recorder, 1919, p.
