ANATOMY, &c.

CHAPTER I.

GENERAL REMARKS.

1. ANATOMY is the science which treats of the structure and relations
of the different parts of animals and plants.

2. It is divided into _Vegetable_ and _Animal_ anatomy. The latter of
these divisions is subdivided into _Human_ anatomy, which considers,
exclusively, human beings; and _Comparative_ anatomy, which treats of
the mechanism of the lower orders of animals.

3. PHYSIOLOGY treats of the functions, or uses of the organs of
animals and plants. Another definition is, "the science of life."

4. This is also divided into _Vegetable_ and _Animal_ physiology, as
it treats of the vegetable or animal kingdom; and into _Human_ and
_Comparative_ physiology, as it describes the vital functions of man
or the inferior animals.

5. HYGIENE is the art or science of maintaining health, or a knowledge
of those laws by which health may be preserved.

6. The kingdom of nature is divided into _organic_ and _inorganic_
bodies. Organic bodies possess organs, on whose action depend their
growth and perfection. This division includes animals and plants.
Inorganic bodies are devoid of organs, or instruments of life. In this
division are classed the earths, metals, and other minerals.

7. In general, organic matter differs so materially from inorganic,
that the one can readily be distinguished from the other. In the
organic world, every individual of necessity springs from some
_parent, or immediate producing agent_; for while inorganic substances
are formed by chemical laws alone, we see no case of an animal or
plant coming into existence by accident or chance, or chemical
operations.

8. Animals and plants _are supported by means of nourishment_, and die
without it. They also increase in size _by the addition of new
particles of matter to all parts of their substances_; while rocks and
mineral
