M ONTMORILLONITE is one of the several clay minerals often found in the clay fraction of soils and its identification is important in problems of soil genesis. During the study of some organic salts of montmorillonite it was observed that characteristic color reactions were given by certain aromatic diamines. Further investigation has shown that these color reactions can be used as qualitative tests for montmorillonite in the presence of other clay minerals and constituents of soils, but in the absence of organic matter.
