Since this paper was written, an excellent report of the pathological effects of asphyxia has been published by Clifford. (Clifford, S. H., Journal of Pediatrics, 18:567, 1941.) This study was made on eleven infants asphyxiated in utero and delivered by cesarean section, thus eliminating possible effects of birth trauma.
