Lecture III

In this way it is possible to penetrate into the plant-forming process. I can only indicate this here. By looking at how the potassium salts are deposited in the birch bark, how something wrestles itself free from this force drawing downward (a process somewhat comparable to what happens when a salt precipitates out of a solution), coming to the process that takes place when the solution rids itself of the salt, we come to see, to grasp in a living way, the process of protein formation, the process I would designate as the albuminizing process. We thus have a path to study what outwardly surrounds the human being, to study it vividly.
