The next table shows all losses of pregnancy sustained by 628 mothers and the rate of loss per 1,000 births for mothers having different numbers of births or reportable pregnancies. For all mothers it was 188.4. “Loss,” as here used, means the sum of infant deaths (or deaths in first year) and stillbirths.
