plasson

When living things made their first appearance on our planet, the very complex nitrogenous compound of carbon that we call plasson, which is the earliest material embodiment of vital action, must have been formed in a purely chemical way from inorganic carbon-compounds.

See Letter 235.), that the vibrations from the protoplasm, or "plasson," of the seminal fluid of the zebra set plasson vibrating in the mare; and that these vibrations continued until the hair of the second colt was formed, and which consequently became barred like that of a zebra.

These are what we call the "cytodes" (cytos = cell), certain living, independent beings, consisting only of a particle of plasson -- an albuminoid substance, which is not yet differentiated into caryoplasm and cytoplasm, but combines the properties of both.

If we agree to call this active substance plasson, and its molecules plastidules, we may say that the individual physiological character of each of these cells is due to its molecular plastidule-movement.

Their whole body consists of soft, structureless plasson.

Nay more, the primordial organic cells could only have originated in the first instance from non-cellular plastides or monads by their homogeneous plasson resolving itself into an internal nucleus and an external protoplasm.

This is not inconsistent with our hypothetical ascription to the plastidules (or molecules of the plasson) of a complex molecular structure.

Like all the other functional-activities of the organic cells, these soul-functions depend ultimately on material phenomena of motion, and more particularly on the motions of the plasson-molecules or plastidules, the ultimate atoms of the protoplasma, and perhaps of the nucleus also; therefore we should be able actually to grasp and explain them, as well as every other cognisable natural process, if we were in a position to refer them to the mechanics of atoms.

The first and lower stage is the cytode, which consists merely of a particle of plasson, or quite simple plasm.
