charcoal, and the sulphur and nitre combined, explode and force the wad,
which forces the ball from the gun, and is borne thro the air till it
reaches the deer, enters his body by displacing the skin and flesh,
deranges the animal functions, and death ensues. The whole and much more
is expressed in the single phrase, "a man killed a deer."

It would be needless for me to stop here, and examine all the operations
of the mind in coming at this state of knowledge. That is not the object
of the present work. Such a duty belongs to another treatise, which may
some day be undertaken, on logic and the science of the mind. The hint
here given will enable you to perceive how the mind expands, and how
language keeps pace with every advancing step, and, also, how
combinations are made from simple things, as a house is made of timber,
boards, shingles, nails, and paints; or of bricks, stone, and mortar; as
the case may be, and when completed, a single term may express the
idea, and you speak of a wood, or a brick house. Following this
suggestion, by tracing the operations of the mind in the young child, or
your own, very minutely, in the acquisition of any knowledge before
wholly unknown to you, as a new language, or a new science; botany,
mineralogy, chemistry, or phrenology; you will readily discover how the
mind receives new impressions of things, and a new vocabulary is adopted
to express the ideas formed of plants, minerals, chemical properties,
and the development of the capacities of the mind as depending on
material organs; how these things are changed and combined; and how
their existence and qualities, changes and combinations, are expressed
by words, to be retained, or conveyed to other minds.

But suppose you talk to a person wholly unacquainted with these things,
will he understand you? Talk to him of stamens, pistils, calyxes; of
monandria, diandria, triandria; of gypsum, talc, calcareous spar,
