in tracing, or searching out, missing articles, as
packages or freight cars.

4. (Mil.) a type of ammunition that emits light or smoke as
it moves toward its target, providing a visible path of
the projectile in flight so that the point of impact may
be observed; -- called also tracer ammunition.
[PJC]
5. (Mil.) the chemical substance used in tracer ammunition to
cause it to be visible in flight.
[PJC]
6. a chemical substance with properties, such as
radioactivity or fluorescence, which make it easily
measurable, used to observe the movements of chemically
related substances through a biological, physical, or
chemical system; -- in biochemistry, also called {labeled
compounds}.
Note: Radioactive tracers are used, for example, to measure
the retention or distribution of residues of drugs
after administration to an animal, to determine the
type and rate of metabolism; also, to measure the rate
of motion of molecules in electrophoresis or the
leakage of small quantities of material from a
container. Small fluorescent tracers may be attached in
many cases to macromolecules such as proteins or
nucleic acids, allowing the motions of such
macromolecules to be easily observed by their acquired
fluorescence, without appreciably changing their
properties. In biological and biochemial systems the
common radioactive isotopes used in tracers are
carbon-14, tritium (hydrogen-3), sulfur-35,
phosphorus-32, and iodine-131; other isotopes are also
used, including non-radioactive isotopes such as
carbon-13.

Geometrical tracery

geometricus; Gr. ?: cf. F. g['e]om['e]trique.]
1. Pertaining to, or according to the rules or principles of,
geometry; determined by geometry; as, a geometrical
solution of a problem.
[1913 Webster]
2. (Art) characterized by simple geometric forms in design
and decoration; as, a buffalo hide painted with red and
black geometrical designs.
Syn: geometric.
[WordNet 1.5]
Note: Geometric is often used, as opposed to algebraic, to
include processes or solutions in which the
propositions or principles of geometry are made use of
rather than those of algebra.
[1913 Webster]
Note: Geometrical is often used in a limited or strictly
technical sense, as opposed to mechanical; thus, a
construction or solution is geometrical which can be
made by ruler and compasses, i. e., by means of right
lines and circles. Every construction or solution which
requires any other curve, or such motion of a line or
circle as would generate any other curve, is not
geometrical, but mechanical. By another distinction, a
geometrical solution is one obtained by the rules of
geometry, or processes of analysis, and hence is exact;
while a mechanical solution is one obtained by trial,
by actual measurements, with instruments, etc., and is
only approximate and empirical.
[1913 Webster]

because their different points may be constructed by the
operations of elementary geometry.

etc., with complicated patterns of interlacing lines; --

Epeira and allied genera, as the garden spider. See
Garden spider.

square frame for ascertaining distances and heights by
measuring angles.

supported by the wall at one end only.

the curves and intersections of the molded bars of the
mullions. Window tracery is imitated in many decorative
objects, as panels of wood or metal either pierced or
in relief. See also Stump tracery under Stump, and
Fan tracery under Fan.
[1913 Webster]
(b) A similar decoration in some styles of vaulting, the
ribs of the vault giving off the minor bars of which
the tracery is composed.
