"Fermentation Reactions of the Ringworm Fungi"

To the Editor:— An artice by Dr. Iwamoto and myself appeared under this title in the December issue of theArchives. Since this article was submitted for publication our attention has been called to a study of The Biologic Reactions of Pathogenic Molds by Dr. S. S. Greenbaum which appeared inThe Journal of Infectious Diseases, July 1922, volume 31, page 26. I regret that we neglected to refer to this report. It contains observations of considerable interest, but we are forced to differ from the conclusions it draws in regard to the fermentative action of the trichophyta.
