Abstract
A series of thirty pairs of saliva-samples from mothers and their new-born infants were tested for their content of group-specific substances. It was found that the distinction between secretors and non-secretors was as sharp in the infants as in the mothers, indicating that this character is fully developed at birth and contradicting the report of Hartmann.
