In many wood-cells (the iLtbriform Fibres' of Sanio) the inner thickening-layers form a shell of cartilaginous or gelatinous consistence, as in the wood of many Papilionaceae. When the outermost layers of the walls of cells which are combined into tissues become gelatinous or mucilaginous, their boundary-line disappears; and the cells, enclosed by the inner shell which is not mucilaginous, appear to be imbedded in a homogeneous jelly; this appearance gave rise to the theory of ' Intercellular Sub- stance,' to which we shall recur. This behaviour occurs in the tissue of some Fucaceae, and also in the endosperm of Ceratonia Siliqua (Fig. 39); cc are the outer layers of the.
