To the Editor:
—In an article on "Prophylactic Inoculation Against Respiratory Infections During the Present Pandemic of Influenza" (The Journal, Jan. 4, 1919, p. 31), Dr. E. C. Rosenow described an atypical form of Streptococcus viridans, as it occurred in and about Rochester, Minn. This description corresponds so closely with that of the prevalent type of Streptococcus viridans, as it occurred at Camp Shelby, Miss., during the winter and spring of 1918, that I think it worth while to draw attention to it.My description of the peculiar type of Streptococcus viridans at Camp Shelby, Miss., which I had the opportunity of studying only during the latter part of the epidemic (April, May and June, 1918), was presented as part of the report by Major George L. Lathrope, M. C., before the Section on Practice of Medicine at the Sixty-Ninth Annual Session of the American Medical Association, Chicago, June, 1918
