To the Editor:
—Reference to the standardization of the Wassermann test was made in two recent numbers of The Journal (Dec. 6, 1919. p. 1773, and Dec. 20, 1919, p. 1897). In neither of these was mention made of research work which is now being conducted at the University of Pennsylvania and the Polyclinic in Philadelphia under the direction of John A Kolmer, and which represents, no doubt, the best attempt which has as yet been made to standardize this important test. The results of this work will, I am informed, appear in a series of about twenty papers in the American Journal of Syphilis. The first two articles of this series were published in the January, 1919, number of that journal. To date, six papers have appeared. It is expected that the balance will appear during the course of this year. All laboratory workers who make the Wassermann test
