Just as the fully formed blossom dies into form and colour and into the volatilising fragrance substances, so does the leaf-and-shoot growth of the oak die into the outer bark. In it, everything that was formerly lived through becomes rigid, dead form; what was green becomes earth-brown and reddish, and what was bound in readily volatile aromatic substances has drifted away. Seen thus, there completes itself in the outer bark a sulphurisation process — a flowering process still close to earth and unfinished. The substances have not yet been entirely lifted free of their physical lawfulness. Calcium, however — raised up into the life of the plant — enters into a bond with the sulphurous oxalic acid that has arisen from this life. It crystallises into calcium oxalate in various crystal forms: rhombohedral, rod- and needle-shaped, or octahedral in double pyramids. One distinguishes crystal sand, individual crystals, twins, druses, and spherites. The oxalic lime (calcium oxalate) arises in the cell plasma. In their early stage the crystals are always enclosed by a plasmatic sheath, which in the outer bark ripens and dies away. What remains in the outer bark of the manifold substance-compositions of the bark are sparingly volatile hydrocarbons and the calcium oxalate crystals. In the latter, the calcium is present in a structure that has received its impress from the living context of the oak. Life has withdrawn from the outer bark; the astral, however — which created this structure (form) — remains bound to the physical-material, and so too to the
