Abstract
IT was recently reported in your pages that prenatal X-irradiation produces a higher incidence of congenital anomalies in the offspring of primiparous mice than in those of multiparous mice, and that although the difference is not great, it is “indeed significant”. In addition to gross external malformations, the classification “congenital anomaly” was also assigned by the writers to resorbed conceptuses, dead foetuses, and stunted survivors, although there is no justification for this practice, because these disparate phenomena may result from unlike effects of irradiation. Thus, collecting them together under one heading probably obscures rather than clarifies the nature of the damage done by prenatal irradiation.
