503 samplings of palmitic acid in amniotic fluid are correlated with gestational age during labor or not. In nine cases of R.D.S. determinations during labor were of very low values, but not in those before labor started. Results are discussed, indicating that values over 2 mg./100 ml. show adequate pulmonary maturity. Inferior values would only be valuable if samples are obtained during labor.
