, n. pl., [NL., fr. Gr. ?, ?, stomach
+ -poda.] (Zo["o]l.)
One of the classes of Mollusca, of great extent. It includes
most of the marine spiral shells, and the land and
fresh-water snails. They generally creep by means of a flat,
muscular disk, or foot, on the ventral side of the body. The
head usually bears one or two pairs of tentacles. See
. [Written also Gasteropoda
Note: The Gastropoda are divided into three subclasses; viz.:
) The Streptoneura or Dioecia, including the
Pectinibranchiata, Rhipidoglossa, Docoglossa, and
) The Euthyneura, including the
Pulmonata and Opisthobranchia. (c
) The Amphineura,
including the Polyplacophora and Aplacophora.
, n. [L. infinitivus: cf. F.
infinitif. See Infinite
Unlimited; not bounded or restricted; undefined.
(Gram.), that form of the verb which merely
names the action, and performs the office of a verbal
noun. Some grammarians make two forms in English: (a
The simple form, as, speak, go, hear, before which to is
commonly placed, as, to speak; to go; to hear. (b
form of the imperfect participle, called the infinitive in
-ing; as, going is as easy as standing.
Note: With the auxiliary verbs may, can, must, might, could,
would, and should, the simple infinitive is expressed
without to; as, you may speak; they must hear, etc. The
infinitive usually omits to with the verbs let, dare,
do, bid, make, see, hear, need, etc.; as, let me go;
you dare not tell; make him work; hear him talk, etc.
Note: In Anglo-Saxon, the simple infinitive was not preceded
by to (the sign of modern simple infinitive), but it
had a dative form (sometimes called the gerundial
infinitive) which was preceded by to, and was chiefly
employed in expressing purpose. See Gerund
Note: The gerundial ending (-anne) not only took the same
form as the simple infinitive (-an), but it was
confounded with the present participle in -ende, or
-inde (later -inge).

opposite limbs become visible or invisible alternately. It
receives different names according to the manner in which
it takes place; as: (a)
Libration in longitude, that
which, depending on the place of the moon in its elliptic
orbit, causes small portions near the eastern and western
borders alternately to appear and disappear each month.

varying position of the moon's axis in respect to the
spectator, causing the alternate appearance and

4. (Physiol.) The act of resping or breathing; the act of
taking in and giving out air; the aggregate of those
processes bu which oxygen is introduced into the system,
and carbon dioxide, or carbonic acid, removed.
Note: Respiration in the higher animals is divided into:
) Internal respiration, or the interchange of
oxygen and carbonic acid between the cells of the body
and the bathing them, which in one sense is a process
of nutrition. (b
) External respiration, or the
gaseous interchange taking place in the special
respiratory organs, the lungs. This constitutes
respiration proper. --Gamgee.
[1913 Webster] In the respiration of plants oxygen is
likewise absorbed and carbonic acid exhaled, but in the
light this process is obscured by another process which
goes on with more vigor, in which the plant inhales and
absorbs carbonic acid and exhales free oxygen.

Southern Asia, Africa, and Madagascar.

1. That which causes fermentation, as yeast, barm, or
Note: Ferments are of two kinds: (a
) Formed or organized
) Unorganized or structureless ferments.
The latter are now called enzymes
and were formerly
called soluble ferments
or chemical ferments
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 they are proteins 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. Before 1960 the term “ferment”
fell out of use. Enzymes are now known to
be globular protein
s, capable of catalyzing a wide
variety of chemical reactions, not merely hydrolytic.
The full set of enzymes causing production of ethyl
alcohol from sugar has been identified and individually
purified and studied. See enzyme
