Stable cationic iron colloid solution was prepared by mixing the Hale's iron colloid (Hale 1946; Mowry 1963) with sodium cacodylate buffer solution. The colloid particles obtained were 30-50 A in size and kept their positive charges in a wide range of pH 1.8-7.6. Observations made on rat kidney tiss
