_Subordinate_, inferior in nature, dignity or power.


Relate a few more of the advantages obtained by a knowledge of
Chemistry.

Many of the wonderful operations of Nature, and the changes which take
place in substances around us, are, by its means, revealed to us. In
every manufacture, art, or walk of life, the chemist possesses an
advantage over his unskilled neighbor. It is necessary to the farmer
and gardener, as it explains the growth of plants, the use of manures,
and their proper application: and indispensable to the physician, that
he may understand the animal economy, and the _effects_ which certain
_causes_ chemically produce; and the nature of animal, vegetable, and
mineral poisons. The study is, therefore, an invaluable branch in the
education of youth: it is useful, not only in the active, but the
_moral_ life, by laying the foundation of an ardent and inquiring
mind. Even an everyday walk in the fields can be productive of
instruction, by a knowledge of it;--and let us always remember, that
"Knowledge is Power."

_Indispensable_, necessary, not to be done without.
