to render the formative-forces organisation of the plant sense-perceptible in a dead image. The principle rests on the change in texture of crystallising copper chloride needles when various plant extracts are added as co-solvents. On account of this fact, during crystallisation on plane glass plates in climate chambers, extract-characteristic and reproducible needle-structures and structural complexes (texture or habit) arise, which can be assessed comparatively.
