lath. See {Latten}, 1st {Lath}.]
1. Any work of wood, metal, plastic, or other solid material,
made by crossing a series of parallel laths, or thin

as a bearing, the bands being vertical and horizontal.

3. (Crystallography) The arrangement of atoms or molecules in

points in space, each point representing the location of
an atom or molecule; called also {crystal lattice} and
{space lattice}.

latticework trusses.

{Lattice girder} (Arch.), a girder of which the wed consists
of diagonal pieces crossing each other in the manner of
latticework.

{Lattice plant} (Bot.), an aquatic plant of Madagascar
({Ouvirandra fenestralis}), whose leaves have interstices
between their ribs and cross veins, so as to resemble

3. (Mus.) The small arch or bar at right angles to the
strings of a violin, guitar, etc., serving of raise them

resistances to be measured is indicated by the absence of
a current in a certain wire forming a bridge or connection
