Lecture IX

This is a process which, if I could say it this way, is almost palpable in the contrast between the pushing forces of magnesium and the forces of fluorine which round off. It is a process which can be found everywhere; in the teeth it occurs from below upwards, rounding itself above, and it also occurs from front to back and from back to front, and from above to below, rounding itself below. Again you can get an almost palpable comprehension of this process if you imagine that with the tendency to push something spherical towards the back, from outside towards the inside, something is formed there, and this is opposed by a sphere-forming process from below to above (see figure 2, red). Between these processes there is mediation by the secretory processes, including also the assimilation of what is secreted by other processes; in short, everything one can call secretory processes in the widest sense because, after all, assimilation depends on the reabsorption of something which is secreted towards the inside. Thus what is active in between can best be called secretory processes.
