Letter from Howard Walter Florey to H Schutze, Lister Institute, Elstree Has received letter from bacteriologist, R W Linton, of Newark, Delaware, who would like some strains of Pasteurella pestis - says Linton's work on improving vaccines is handicapped by lack of suitable strains - is particularly interested in Professor Otten's strains from Java - asks if Schutze would be willing to send some subcultures. 14 February 1942
