Chemical Chem"ic*al, n.

Chemical attractionAttraction At*trac"tion, n. [L. attractio: cf. F. attraction.]
1. (Physics) An invisible power in a body by which it draws
anything to itself; the power in nature acting mutually
between bodies or ultimate particles, tending to draw them
together, or to produce their cohesion or combination, and
conversely resisting separation.
Note: Attraction is exerted at both sensible and insensible
distances, and is variously denominated according to
its qualities or phenomena. Under attraction at
sensible distances, there are, -- (1.)
Attraction of gravitation, which acts at all distances
throughout the universe, with a force proportional
directly to the product of the masses of the bodies and
inversely to the square of their distances apart. (2.)
Magnetic, diamagnetic, and electrical attraction, each
of which is limited in its sensible range and is polar in
its action, a property dependent on the quality or
condition of matter, and not on its quantity. Under
attraction at insensible distances, there are, -- (1.)
Adhesive attraction, attraction between surfaces of
sensible extent, or by the medium of an intervening
substance. (2.)
Cohesive attraction, attraction between ultimate particles,
whether like or unlike, and causing simply an aggregation
or a union of those particles, as in the absorption of
gases by charcoal, or of oxygen by spongy platinum, or the
process of solidification or crystallization. The power in
adhesive attraction is strictly the same as that of
cohesion. (3.)
Capillary attraction, attraction causing a liquid to rise,
in capillary tubes or interstices, above its level
outside, as in very small glass tubes, or a sponge, or any
porous substance, when one end is inserted in the liquid.
It is a special case of cohesive attraction. (4.)
Chemical attraction, or
affinity, that peculiar force which causes elementary
atoms, or groups of atoms, to unite to form molecules.
2. The act or property of attracting; the effect of the power
or operation of attraction. --Newton.
3. The power or act of alluring, drawing to, inviting, or
engaging; an attractive quality; as, the attraction of
beauty or eloquence.
4. That which attracts; an attractive object or feature.
Syn: Allurement; enticement; charm. Chemical fuzeFuze Fuze, n.
A tube, filled with combustible matter, for exploding a
shell, etc. See Fuse, n.
Chemical fuze, a fuze in which substances separated until
required for action are then brought into contact, and
uniting chemically, produce explosion.
Concussion fuze, a fuze ignited by the striking of the
projectile.
Electric fuze, a fuze which is ignited by heat or a spark
produced by an electric current.
Friction fuze, a fuze which is ignited by the heat evolved
by friction.
Percussion fuze, a fuze in which the ignition is produced
by a blow on some fulminating compound.
Time fuze, a fuze adapted, either by its length or by the
character of its composition, to burn a certain time
before producing an explosion. chemical harmoniconSinging Sing"ing,

1. An apparition; a specter. [Obs.]
2. (Opt.)
(a) The several colored and other rays of which light is
composed, separated by the refraction of a prism or
other means, and observed or studied either as spread
out on a screen, by direct vision, by photography, or
otherwise. See Illust. of Light, and Spectroscope.
(b) A luminous appearance, or an image seen after the eye
has been exposed to an intense light or a strongly
illuminated object. When the object is colored, the
image appears of the complementary color, as a green
image seen after viewing a red wafer lying on white
paper. Called also ocular spectrum.
Absorption spectrum, the spectrum of light which has passed
through a medium capable of absorbing a portion of the
rays. It is characterized by dark spaces, bands, or lines.
Chemical spectrum, a spectrum of rays considered solely
with reference to their chemical effects, as in
photography. These, in the usual photogrophic methods,
have their maximum influence at and beyond the violet
rays, but are not limited to this region.
Chromatic spectrum, the visible colored rays of the solar
spectrum, exhibiting the seven principal colors in their
order, and covering the central and larger portion of the
space of the whole spectrum.
Continous spectrum, a spectrum not broken by bands or
lines, but having the colors shaded into each other
continously, as that from an incandescent solid or liquid,
or a gas under high pressure.
Diffraction spectrum, a spectrum produced by diffraction,
as by a grating.
Gaseous spectrum, the spectrum of an incandesoent gas or
vapor, under moderate, or especially under very low,
pressure. It is characterized by bright bands or lines.
Normal spectrum, a representation of a spectrum arranged
upon conventional plan adopted as standard, especially a
spectrum in which the colors are spaced proportionally to
their wave lengths, as when formed by a diffraction
grating.
Ocular spectrum. See Spectrum, 2
(b), above.
Prismatic spectrum, a spectrum produced by means of a
prism.
Solar spectrum, the spectrum of solar light, especially as
thrown upon a screen in a darkened room. It is
characterized by numerous dark lines called Fraunhofer
lines.
Spectrum analysis, chemical analysis effected by comparison
of the different relative positions and qualities of the
fixed lines of spectra produced by flames in which
different substances are burned or evaporated, each
substance having its own characteristic system of lines.
Thermal spectrum, a spectrum of rays considered solely with
reference to their heating effect, especially of those
rays which produce no luminous phenomena. Chemically

soluble or chemical fermentsFerment Fer"ment, n. [L. fermentum ferment (in senses 1 & 2),
perh. for fervimentum, fr. fervere to be boiling hot, boil,
ferment: cf. F. ferment. Cf. 1st Barm, Fervent.]
1. That which causes fermentation, as yeast, barm, or
fermenting beer.
Note: Ferments are of two kinds: (a) Formed or organized
ferments. (b) Unorganized or structureless ferments.
The latter are also called soluble or chemical
ferments, and enzymes. Ferments of the first class
are as a rule simple microscopic vegetable organisms,
and the fermentations which they engender are due to
their growth and development; as, the acetic ferment,
the butyric ferment, etc. See Fermentation.
Ferments of the second class, on the other hand, are
chemical substances, as a rule soluble in glycerin and
precipitated by alcohol. In action they are catalytic
and, mainly, hydrolytic. Good examples are pepsin of
the dastric juice, ptyalin of the salvia, and disease
of malt. Stereo-chemical
