When we move from these proteolytic lumps of mucus to living organisms
with a constant distribution of matter, we find the difference in the tissues
corresponding to the difference in relative position. Higher Protozoa,
as Protophyta, the main differentiation occurs at the cellular
the shell and the contents of the cells, respectively the main opposites
conditions, namely, in terms of both internal and external. Moving from
organisms belonging to the class of one-celled organisms to the lowest of
compiled by a combination of cells, we note everywhere the relationship between the difference in
device and the difference in surrounding circumstances. The lack of a definite
organization in sponges, leaking everywhere jet of seawater corresponds to
the absence of a specific difference in the terms. At the Thalassicolla of Professor
Huxley - a transparent, colourless body, floating passively on the sea surface
