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.
