They have no significance whatever,since the flat epithelia continually desquamate in health, though in asmall amount only. As soon as they occur with pus-corpuscles and withcuboidal epithelia, they have a pathological significance. These flat epi-thelia may be seen either singly or in clusters of varying size. Although.

Their number, together with the size EPITHELIA. 10!) of the cuboidal epithelia and the fact of their not containing bacteria, isas a rule sufficient to clear up the diagnosis. Cuboidal epithelia from the middle layers are never found in normalurine; they may be scant} or numerous. When cuboidal epithelia arepresent in moderate or large numbers, with many flat epithelia from theupper layers, the diagnosis of an acute process can be made. If, on theother hand, the upper layers are scanty or entirely absent, the process isa chronic one. Whe
