Since the degree of largeness of a dose is relative and depends on the frame of reference, there may be reason for making the amount administered a strong point in discussing the half-life of steroids in the newborn. Many physiologic and biochemical functions of infants differ in degree from similar functions in adults, and we feel it is of importance to consider these factors when investigating allied problems. While we agree it is important to establish the
