Note 37 — Chapter VII · GENERAL DIFFERENCES OF THE TWO LIVES WITH RESPECT TO VITAL POWER.
F. Gold translation
We know that the organs are nourished, that the glands secrete, we know that certain vessels absorb (whether they be the lymphatics or not,) but we do not know, that all this is produced by a partial oscillatory movement in each fibre, in each molecule. No one can be certain that this movement takes place, because no one has seen it.
