The teratogenic effect of thalidomide has recently received much attention. The following case illustrates a neonate's "resistance"—in contrast to the usually expected "susceptibility"—to an inordinate amount of transplacentally acquired bromide, supporting Day's contention that prediction of toxicity is risky.1
