The sensitivity of allophane soil to dehydration was studied from the pH dependence of electrophoretic mobility. (1) The isoelectric point of allophane soil rose from pH ca. 3.8 to pH ca. 5.5 by air drying. This result suggests that the air drying treatment promotes the positive colloidal character of allophane soil in weak acid medium. (Fig. 1 ) (2) The curve of mobility of pF 4.8 material revealed the intermediate feature between those of moist and air dried materials. (Fig. 1
