blind belief In theology, or the accept
ance Of the scientific theory Of evolu-
tionized man as afact. at
The BathJbius, the most remarkable
of all Monera, was discovered by Hux-
ley in 1858. This wonderful Moneron
lives in the deepest parts Of the sea,
and especially ia the Atlantic ocean.
In some places itcovers the whole floor
of the sea in such masses that the fine
mud or "ooze" at the bottom consists
mainly of living slime. The proto-
plasma in these formless nets does not
appear differentiated at all; each small
particle is capable of forming an indi-
vidual by equal division: it is an or
ganism without organs. Nutrition is
by absorption. It canaot be said that
in generation, it sexually reproduces
itself. The Moneron gradually con-
tracts in the middle, and it might liter
ally be said "to break itself in two"-
thus forming two individuals. The
con6guration constantly changes
small blunt arms appear and disappear
the whole resembling q disfigured
starfish. In the light OF such positive
knowledge, the theory of spontaneous
generation becomes a necessity; for
the Monera actually stands on the
boundary between organic and inor-
ganic bodies. 1t may be said in premise,
before giving the sequence Of phylo-
genetic descent, that the parent forms
themselves, with their specific character
istics, became extinct at more or less
distant period; the extant forms which
come nearer them. differing only in
outward essentials and external con-
figaration. No apology is offered for
the apparent intervals of disconn.c-
stion and oonGraity In the appended
arrangement OF evolutionized organ
isms. Limited space will not allow
for the minutia Of detail; and ii the
subject appeals at all, closer investi-
CATION will only serve to bear out the
truth and naturalization of the theory
of eyolutionized organic life.
First stage: the form of the ancestors
of man is equal to the simple indi-
vidual Of the first order, simple
plastid. aa =.
Second stage; the ancestors of man
are single. living simple cytodes.
Third stage, the ancestors of man
are single living, simple cells.
Fourth stage: the ancestors of man
consist of closely-united society of
many homogeneous cells.
Fifth stage: the ancestors Of man
are many-celled primitive animals of
the simplest kind.
Sixth stage: the ancestors of man
are many-celled primitive animals like
that of certain planula larvae, hollow
spheres, the wall of which consists of
q single stratum Of cells.
Seventh stage: the body encloses an
intestinal cavity with mouth, with
two and then four germ-Iayers.
Eighth stage: the ancestors of man
are primitive worms, afterward worms
of higher rank, and finally the note
chord animais-the note-chord being
cartilaginols lateral mass that de-
veloped by ossification into the primi-
tive spine.

Ninth stage: the ancestors of man
are vertebrates-the skin-sensory plate
has divided itself into the horn plate.
medullary tube, and primitive kidneys.
The skin-fibrous layer has divided into
leatherplate and primitive vertebra.
From the intestinal-fbrou layer origi-
mates the heart with the main blood
vessels. A
Tenth stage: the ancestors of man
are skull-less vertebrates, like extant
Amphioxus. Some OF the primitive
vetebr9 have broken off. The head is
not entirely distinct from the trunk.
The medullafy-tube has not separated
into brain-bladders, and the heart is
very simple; the four chambers not
yet appearipg. The skull is wanting,
as are jaws and limbs.
Eleventh stage: the ancestors of man
are jaw-less, skulled animals. The
head is beconliug more distinct from
the trunk. The anterior end of the
medullafy tube enlarges into q blad-
der-like structure and forms the brain
which soon differentiates itself into Eve
small brain bladders; at the sides of
these appear the three higher organs
of sense. The heart is divided into
