Homology \Ho*mol"o*gy\, n. [Gr. ? agreement. See Homologous.]
1. The quality of being homologous; correspondence; relation;
as, the homologyof similar polygons.
[1913 Webster]
2. (Biol.) Correspondence or relation in type of structure in
contradistinction to similarity of function; as, the
relation in structure between the leg and arm of a man; or
that between the arm of a man, the fore leg of a horse,
the wing of a bird, and the fin of a fish, all these
organs being modifications of one type of structure.
[1913 Webster]
Note: Homology indicates genetic relationship, and according
to Haeckel special homology should be defined in terms
of identity of embryonic origin. See Homotypy, and
Homogeny.
[1913 Webster]
3. (Chem.) The correspondence or resemblance of substances
belonging to the same type or series; a similarity of
composition varying by a small, regular difference, and
usually attended by a regular variation in physical
properties; as, there is an homology between methane,
CH4, ethane, C2H6, propane, C3H8, etc., all members
of the paraffin series. In an extended sense, the term is
applied to the relation between chemical elements of the
same group; as, chlorine, bromine, and iodine are said to
be in homology with each other. Cf. Heterology.
[1913 Webster]
General homology (Biol.), the higher relation which a
series of parts, or a single part, bears to the
fundamental or general type on which the group is
constituted. --Owen.
Serial homology (Biol.), representative or repetitive
relation in the segments of the same organism, -- as in
the lobster, where the parts follow each other in a
straight line or series. --Owen. See Homotypy.
Special homology (Biol.), the correspondence of a part or
organ with those of a different animal, as determined by
relative position and connection. --Owen.

Methane \Meth"ane\, n. [See Methal.] (Chem.)
A light, colorless, gaseous, inflammable hydrocarbon, CH4;
marsh gas. It is the simplest of the aliphatic hydrocarbons.
See Marsh gas, under Gas.
[1913 Webster]
Methane series (Chem.), a series of saturated hydrocarbons,
of which methane is the first member and type, and
(because of their general chemical inertness and
indifference) called also the paraffin (little affinity)
series. The lightest members are gases, as methane,
ethane; intermediate members are liquids, as hexane,
heptane, etc. (found in benzine, kerosene, etc.); while
the highest members are white, waxy, or fatty solids, as
paraffin proper.

impression, form of character, model, from the root of ? to
beat, strike; cf. Skr. tup to hurt.]

comes to be actually exhibited. --South.
[1913 Webster]
4. That which possesses or exemplifies characteristic
qualities; the representative. Specifically:
(a) (Biol.) A general form or structure common to a number
of individuals; hence, the ideal representation of a
species, genus, or other group, combining the
essential characteristics; an animal or plant
possessing or exemplifying the essential
characteristics of a species, genus, or other group.
Also, a group or division of animals having a certain
typical or characteristic structure of body maintained
within the group.
[1913 Webster]

divisions or types. --Haeckel.
[1913 Webster]
(b) (Fine Arts) The original object, or class of objects,
scene, face, or conception, which becomes the subject
of a copy; esp., the design on the face of a medal or

[1913 Webster]
(c) (Chem.) A simple compound, used as a mode or pattern
to which other compounds are conveniently regarded as
being related, and from which they may be actually or
theoretically derived.

5. (Typog.)
(a) A raised letter, figure, accent, or other character,
cast in metal or cut in wood, used in printing.
(b) Such letters or characters, in general, or the whole
quantity of them used in printing, spoken of
collectively; any number or mass of such letters or
characters, however disposed.
[1913 Webster]
Note: Type are mostly made by casting type metal in a mold,
though some of the larger sizes are made from maple,
mahogany, or boxwood. In the cut, a is the body; b, the
face, or part from which the impression is taken; c,
the shoulder, or top of the body; d, the nick
(sometimes two or more are made), designed to assist
the compositor in distinguishing the bottom of the face
from t`e top; e, the groove made in the process of
finishing, -- each type as cast having attached to the
bottom of the body a jet, or small piece of metal
(formed by the surplus metal poured into the mold),
which, when broken off, leaves a roughness that
requires to be removed. The fine lines at the top and
bottom of a letter are technically called ceriphs, and
when part of the face projects over the body, as in the
letter f, the projection is called a kern.
[1913 Webster] The type which compose an ordinary book
font consist of Roman CAPITALS, small capitals, and
lower-case letters, and Italic CAPITALS and lower-case
letters, with accompanying figures, points, and
reference marks, -- in all about two hundred
characters. Including the various modern styles of
fancy type, some three or four hundred varieties of
face are made. Besides the ordinary Roman and Italic,
some of the most important of the varieties are

[1913 Webster] The foregoing account is conformed to
the designations made use of by American type founders,
but is substantially correct for England. Agate,
however, is called ruby, in England, where, also, a
size intermediate between nonpareil and minion is
employed, called emerald.
[1913 Webster]
Point system of type bodies (Type Founding), a system
adopted by the type founders of the United States by which
the various sizes of type have been so modified and
changed that each size bears an exact proportional
relation to every other size. The system is a modification
of a French system, and is based on the pica body. This
pica body is divided into twelfths, which are termed
``points,'' and every type body consist of a given number
of these points. Many of the type founders indicate the
new sizes of type by the number of points, and the old
names are gradually being done away with. By the point
system type founders cast type of a uniform size and
height, whereas formerly fonts of pica or other type made
by different founders would often vary slightly so that
they could not be used together. There are no type in
actual use corresponding to the smaller theoretical sizes
of the point system. In some cases, as in that of ruby,
the term used designates a different size from that
heretofore so called.
