In previous investigations1 it was observed that the antistreptolysin titer of infants at the onset of infections was lower than that of older persons and that their antistreptolysin response to infection with beta hemolytic streptococci was minimal. Furthermore, Wilson, Wheeler and Leask2 observed that the average antistreptolysin titer of a group of new-born infants (56 units)3 was approximately that of their mothers (50 units). Repeated determinations showed that the mothers' titers remained at a constant level while those of the infants diminished progressively. Wilson and her associates considered this an indication of placental transmission of the antibody. Blood drawn from the umbilical cords of the majority of infants studied by Coburn and Pauli4 contained more antistreptolysin than did the corresponding maternal blood.
Lippard and Johnson1 encountered occasional infants whose blood clots showed maximum resistance to dissolution by hemolytic streptococci during the early part of an
