d even the egg is but a
modified epithelial cell attached to the walls of the ovary, which in
turn is morphologically but a gland. Thus Nature deals in simples, and
with her units of structure elaborates as her crowning work a temple in
which the mind of man, formed in the image of God, may dwell. Her
results are not the less marvellous because we are beginning to dimly
trace the process by which they arise. It should not lessen our awe and
reverence for Deity, if with minds made to adore, we also essay to trace
the movements of His hand in the origin of the forms of life.
Some writers of the evolution school are strenuous in the belief that
the evolution hypothesis overthrows the idea of archetypes, and plans of
structure. But a true genealogy of animals and plants represents a
natural system, and the types of animals, be they four, as Cuvier
taught, or five, or more, are recognized by naturalists through the
study of dry, hard, anatomical facts. Accepting, then, the type of
articulates as founded in nature from the similar modes of development
and points of structure perceived between the worms and the crustacea on
the one hand, and the worms and insects on the other, have we not a
strong genetic bond uniting these three great groups into one grand
subkingdom, and can we not in imagination perceive the successive steps
by which the Creator, acting through the laws of evolution, has built up
the great articulate division of the animal kingdom?

[Insects, Myriopods and Spiders] which I have called Protracheata in my
'General Morphology' has developed directly from the true Annelides
(Coelminthes), or, the next thing to this (_zunachst_), out of
Zoea-form Crustacea (Zoepoda), will be hereafter established only
through a sufficient knowledge and comparison of the structure and mode
of growth of the Tracheata, Crustacea and Annelides. In either case is
the root of the Tracheata, as also of the Crustacea, to be sought in the
group of the true jointed worms (Annelides, Gephyrea and Rotatoria." He

viz., in the Devonian.]
