Through a mechanical error in correcting the type for the article, "Clinical Evaluation of Erythromycin" by Drs. Emitt H. Shoemaker and Ellard M. Yow, in the March issue of the Archives, page 397, the sense of the addendum was completely destroyed. The entire addendum should read as follows.
"Subsequent experience with the administration of erythromycin has confirmed the results reported in this paper. A patient with a staphylococcal bacteremia and meningitis has been treated with large doses of erythromycin, resulting in the sterilization of the blood stream but not the spinal fluid. This observation, along with the persistence of infection in empyema cavities reported in this paper, suggests that the diffusion of erythromycin across the serous membranes cannot always be relied upon. Erythromycin has also been used unsuccessfully in the treatment of another patient with overwhelming staphylococcal septicemia."
