Allophane and imogolite were negatively stained with LaCl3 and examined in an electron microscope. Many white spots having a diameter of 20 to 25 Å and white striatums having a width of 8 to 10 Å appeared against dark background in the micrographs of allophane and imogolite, respectively. This is taken as an evidence of the presence of the hollow in the unit particles of allophane and fibrous structural units of imogolite. In some micrographs unit particles of allophane appeared to have thicker and electron denser wall. This is interpreted in terms of positive staining through simultaneous adsorption of La3+ and CI- ions.
