Natural history, in its broadest sense, a history or
description of nature as a whole, including the sciences

paleontology, chemistry, and physics. In recent
usage the term is often restricted to the sciences of
botany and Zoology collectively, and sometimes to the
science of zoology alone.
Natural law, that instinctive sense of justice and of right
and wrong, which is native in mankind, as distinguished
from specifically revealed divine law, and formulated
human law.
Natural modulation (Mus.), transition from one key to its

considers those effects only which are unaccompanied by
any change of a chemical nature; -- contrasted with
mental philosophy and moral philosophy.
Natural scale (Mus.), a scale which is written without
flats or sharps.
Note: Model would be a preferable term, as less likely to
mislead, the so-called artificial scales (scales
represented by the use of flats and sharps) being
equally natural with the so-called natural scale.
Natural science, the study of objects and phenomena

analogous, in their operation and results, to designed
selection in breeding plants and animals, and resulting in
the survival of the fittest; the elimination over time of
species unable to compete in specific environments with
other species more adapted to survival; -- the essential
mechanism of evolution. The principle of natural selection
is neutral with respect to the mechanism by which
inheritable changes occur in organisms (most commonly
thought to be due to mutation of genes and reorganization
of genomes), but proposes that those forms which have
become so modified as to be better adapted to the existing
environment have tended to survive and leave similarly
adapted descendants, while those less perfectly adapted
have tended to die out through lack of fitness for the
environment, thus resulting in the survival of the
fittest. See Darwinism.
Natural system (Bot. & Zool.), a classification based upon
real affinities, as shown in the structure of all parts of
the organisms, and by their embryology.

divisions. --Gray.

theological science which treats of those evidences of the
existence and attributes of the Supreme Being which are

her, etc.; -- so called as being uttered in the easiest
open position of the mouth organs. See Neutral vowel,
under Neutral and Guide to Pronunciation, [sect] 17.

Chemist. See Alchemy.]
1. That branch of science which treats of the composition of
substances, and of the changes which they undergo in

molecules, which depend upon variations of the number,
kind, or mode of arrangement, of the constituent atoms.

the finest grade of subdivision hitherto attained.

constitution of molecules. See Atom, Molecule.

chimistry, chimist, chimical, etc.; and the
pronunciation was conformed to the orthography.
[1913 Webster]
Inorganic chemistry, that which treats of inorganic or
mineral substances.
Organic chemistry, that which treats of the substances
which form the structure of organized beings and their
products, whether animal or vegetable; -- called also
chemistry of the carbon compounds. There is no
fundamental difference between organic and inorganic
chemistry.
Physiological chemistry, the chemistry of the organs and
tissues of the body, and of the various physiological
processes incident to life.
Practical chemistry, or Applied chemistry, that which
treats of the modes of manufacturing the products of
chemistry that are useful in the arts, of their
applications to economical purposes, and of the conditions
essential to their best use.
Pure chemistry, the consideration of the facts and theories
of chemistry in their purely scientific relations, without
necessary reference to their practical applications or
mere utility.

it to be viewed as truly organic, i.e. included in the
