The cellulose has been extracted, and the wall consists only of wood-gum. The fissures are a result of drying-up, but they do not extend into the jirimary wall «, l>. Crossing of the fissures takes place at the Iwrdercd pits c, and at the bnre-holes it and f; J, simple fissures. (After H. Hartig.) kind, the primary wall, containing l)Ut little cellulose, is hardly atlected, and the secondary membranes shrink together, so that numerous fissures are produced running in a spiral direction, corresiionding with that of the stratification (Figs. I .'> and 14.) The tertiary membrane varies in its nature ; it may consist of ])ure cellulose or be more or less lignified, oi- even cuticularized.
