The relationship between the locomotive velocity of amoeba which had not been fed for 24 h and the concentration of the test solutions was examined. With solutions of L‐amino acids, protein substances, and alcian blue 8GS, an increase in velocity began at very low concentrations, reaching a maximum at a higher concentration and as the concentration increased further, the velocity fell to zero. In contrast, no increase was observed with D‐glutamic acid and β‐alanine. Moreover, the velocity of well fed amoebae did not increase significantly even in L‐amino acid solution. These results may suggest a correlation between orthokinesis and amoeboid phagocytosis.
