Abstract
IN previous communications1,2 the existence of a third normal, embryonic hæmoglobin was reported to be present in the blood of fœtuses up to five months of intra-uterine life. The hæmolysates of the blood of these fœtuses were characterized by their electrophoretic mobility on filter paper in a buffer solution of p H 8.6, which was slower than that shown by the hæmolysates obtained from the cord blood of full-term new-borns. The paper electrophoresis method did not permit us, however, to separate the different hæmoglobin fractions present either in the fœtal or in the embryonic blood.
