Copy of a letter from Frederick George Novy, Professor of Bacteriology, University of Michigan to George Henry Falkiner Nuttall, Editor, Journal of Hygiene Complains that Ross has ignored his views on F Schaudinn's work in his paper in the April number of the Journal of Hygiene and gives an outline of his correspondence with Ross on trypanosomes. Ross knew about his work, although he is now being given the credit for pointing out F Schaudinn's error and he has also prevented WS Patton from making similar mistakes to Schaudinn 9/5/1906
