responds
with the universally acknowledged ideas of accountability; for, with a
wise, and efficient Cause, we infer there is an intelligent creation,
and the desire to communicate, guide and bless, is responded to by man,
who loves, obeys, and enjoys. Nothing is gained by attributing to nature
vicegerent forces. Is it not preferable to say that she responds to
intelligent, loving Omnipotence? Our finiteness is illustrated by our
initiation into organized being. Emerging from a rayless atom, too
diminutive for the sight, we gradually develop and advance to the
maturity of those _conscious powers_, the exercise of which furnishes
indubitable evidence of our immortality. We are pervaded with invisible
influences, which, like the needle of the compass trembling on its
pivot, point us to immortality as our ultimate goal, where in the sunny
clime of Love, even in a spiritual realm of joy and happiness, we may
eternally reign with Him who is all in all.

CHAPTER II.

PHYSIOLOGICAL ANATOMY.

THE BONES.

All living bodies are made up of tissues. There is no part, no organ,
however soft and yielding, or hard and resisting, which has not this
peculiarity of structure. The _bones_ of animals, as well as their flesh
and fat, are composed of tissues, and all alike made up of cells. When
viewed under a microscope, each cell is seen to consist of three
distinct parts, a _nucleolus_, or dark spot, in the center of the cell,
around which lies a mass of granules, called the _nucleus;_ and this, in
turn, is surrounded with a delicate, transparent membrane, termed the
_envelope_. Each of the granules composing the nucleus assimilates
nourishment, thereby growing into an independent cell, which possesses a
triple organization similar to that of its parent, and in like manner
reproduces other cells.

A variety of tissues enters into the composition of an animal structure,
yet their differences are not always distinctly marked, since the
characteristics of some are not unlike those of others. We shall notice,
however, only the more important of the tissues.

The _Areolar_, or _Connective Tissue_, is a complete network of delicate
fibers, spread over the body, and serves to bind the various organs and
parts together. The fibrous and serous tissues a
