Abstract
SUMMARY. A small soil amoeba was purified by an agar‐surface migration method. The amoeba was grown axenicly in a liquid medium composed of 1% proteose peptone, 1% glucose, and inorganic salts. The amoeba was identified as a species of Acanthamoeba. A hypothesis on the mechanism of agar‐surface purification of amoebæ is proposed. The nutritional requirements of this isolate are discussed; it is concluded that this organism metabolizes glucose.
