divided into three kingdoms; the first consisting of minerals, the
second of vegetables, and the third of animals. The Mineral Kingdom
comprises all substances which are without those organs necessary to
locomotion, and the due performance of the functions of life. They are
composed of the accidental aggregation of particles, which, under
certain circumstances, take a constant and regular figure, but which are
more frequently found without any definite conformation. They also
occupy the interior parts of the earth, as well as compose those huge
masses by which we see the land in some parts guarded against the
encroachments of the sea. The Vegetable Kingdom covers and beautifies
the earth with an endless variety of form and colour. It consists of
organized bodies, but destitute of the power of locomotion. They are
nourished by means of roots; they breathe by means of leaves; and
propagate by means of seed, dispersed within certain limits. The Animal
Kingdom consists of sentient beings, that enliven the external parts of
the earth. They possess the powers of voluntary motion, respire air, and
are forced into action by the cravings of hunger or the parching of
thirst, by the instincts of animal passion, or by pain. Like the
vegetable kingdom, they are limited within the boundaries of certain
countries by the conditions of climate and soil; and some of the species
prey upon each other. Linnaeus has divided them into six
classes;--Mammalia, Birds, Fishes, Amphibious Animals, Insects, and
Worms. The three latter do not come within the limits of our domain; of
fishes we have already treated, of birds we shall treat, and of mammalia
we will now treat.
