Numbers 25 and 33 are duplicate cultures obtained from Lelito at different times and 34 is a duplicate culture obtained from Pierce.One of the strains is the well-known "Rawlings" strain, which has been used for many years in England and the United States for the preparation of typhoid vaccine. It was obtained for this collection from the Royal Army Medical School, England, in March, 1908. 2. A group of older cultures, consisting of 10 strains. Three of these had been obtained from Dr. ]. C. Torrey of the Cornell University Medical School, New York, more than 5 years ago; 5 were isolated by one of us (Teague) about 3 years ago at the Quarantine Laboratory, Port of New York; and 2 came from Boston. Four of the 5 cultures from the Quarantine Laboratory were from blood cultures, the other from a stool culture; the 2 cultures from Boston were obtained from blood cultures.3. A group of 12 cultures obtained from R. C. Colwell, 1st Lieut. Sanitary Corps, U. S. Army, through the courtesy of Lieut.-Col. H. J. Nichols. It was stated that these cultures did not ferment xylose and that they had been selected by Lieut. Colwell, precisely on account of this property, from a large number of cultures of B. typhosus obtained from American army camps in France. The 12 strains were derived from 9 patients, cultures from both blood and stools of 3 patients having been included. The duplicate strains were the following: C-175 Blood culture C-176 Stool culture C-48 Blood culture C-59 Stool culture C-188 Blood culture C•189 Stool culture Six of these 12 cultures were isolated between Nov. 22, 1918, and Feb. 6, 1919.
