To the Editor:—I was extremely interested in the article Pulmonary Function Studies in Children, which appeared in the August, 1960, issue of the American Journal of Diseases of Children. It is indeed gratifying to realize that pediatricians are becoming increasingly aware of the potential value of objective pulmonary measurements in children.

I would like to call your attention to an inaccuracy contained in the editorial caption which precedes this fine article. The caption reads: "Here for the first time are data on normal preadolescents." The following references should serve to dispel this notion:

  1. Morse, M.: Schultz, F. W., and Cassels, D. E.: Lung Volume and Its Subdivisions in Normal Boys 10-17 Years of Age, J. Clin. Invest. 31:380, 1952.

  2. Engstrom, I.; Karlberg, P., and Kraepelien, S.: Respiratory Studies in Children: I. Lung Volumes in Healthy Children, 6 to 14 Years of Age, Acta Pediat. 45:277, 1956.
