1837. This organ stands, like the air, upon the middle rate of oxydation; the oxygen becomes alternately united with it and set free; which is neither possible in the point-form, as being that which incessantly liberates oxygen, nor in the globe-form, as being that which always holds or retains the oxygen in union with it.
1838. This tissue must consist of firm or solid nervous granules, which have been serially co-arranged in lines or radii. Such organic lines are called Fibres.
1839. The fibrous is the third original tissue, which appears in the animal organization.
1840. The nerve acts upon the fibres as upon the bone, or as a Central upon a Peripheric, as the light upon the air.
1841. Thereby the soft fibre is polarized; the poles are mutually attracted and repelled, and motion of the fibres originates, their extremities approximating or withdrawing by virtue of the polarity. Contractile fibres are called sarcose or fleshy fibres.
Flesh.
1842. The flesh is the median formation between nerve and bone. It is half nervous mass, therefore sentient, half bone, therefore moving.
1843. The essence of the motion resides in the muscle, not in the nerve. Such is the cause of motion, the muscle being the self-moving, the bone that which is moved.
1844. The flesh must surround the bone, as the air or water surrounds the earth.
1845. The flesh is a terrestrial substance, just as the bone is; the nerve is a cosmical substance, and on that account the mediator of everything.
