I reject this assertion, because oxygen is no nutrient, but the substance that fertilises the oppositely-charged (geospheric) fructigenic ethericities. These enter the plants via the protoplasm at the tips of the roots (see fig. 15). In more highly organised life-forms they enter the hermetically sealed blood- or sap-streams by way of the intestinal filtration systems; in other words, by way of diffusion. They then proceed through the diffusive orifices of the leaves, needles, gills and lungs and make possible the intermixtures upon whose character and capacity of accommodation the formation of pathogenic or animating entities depends, which at this time are in an atomic state.
