VI. Diphtheria and Influenza—Crossed Eyes

Now, what happens in the case of diphtheria? In diphtheria, the skin suddenly becomes weak and subdued. The activity of the skin is too weak, so a person with diphtheria suffers from too little exchange of air through the skin. Indeed, this is the main problem. The skin, including the skin of the nose exposed to the external surroundings, does not breathe enough, and it becomes too weak. The in-streaming activity, indicated in my sketch by the arrows, no longer functions properly, and the heart senses this. The heart also senses that the kidneys work upward. What is it that the kidneys are doing? The heart can no longer restrain the activity of the kidneys, which shoots upward. Long before inflammation of the kidneys, that is, nephritis, sets in, the activity of the kidneys is already shooting upward. Because the skin activity is no longer working effectively from outside, superfluous skin forms on the inside. Because the, skin's activity from the outside is not working properly, a superfluous skin is formed, filling everything out, because the kidneys' activity is too strong.
