The minimun daily dose of the liver which after the administration over consecutive three days was effective in prolonging the time-period for the minimum red cell count, was found about 0.5 gr fresh bovine liver per kg body weight (Table I). By using the above minimum daily dose of a sample liver-extract, accordingly, an approximate estimation has been made on the antianaemic potency in livers of several marine animals. Nearly no difference in the potency has been found between the liver-extracts of whale, yellow tail, shark and bovine (Table I and II). It has been observed in both whale and yellow tail that the subcutaneous administration of an extract of mixture of liver and stomach showed a greater potency than that of the liver-extract only (Table III). A comparison of the results contained in Table IV with those in Table II and III reveals that the oral administration of liver-extract showed a little higher potency than the subcutaneous administration.
