Dear Mise Louderaill:

In reply to your letter of "December 15", there is a considerable volum

of literature on bacterial genetics, to which I can hardly do justice in a

semester course. Al] I cen do is to refer you to a munber of review articles,

from yhich you can glean further references. May I suggest that you consult

the following: Heredity, 2: 145-198 1948; Bact. Reve. 11:1-40 1947 and

ll: 75-114, 19473 Ann. Rev. Microbiology, Vole. 3 and 4, 1949 andi 1950; and the

Cold Spring Harbor Sympoaium on Quantitative Biclogy, Yol. 11, 1946. You might
_ also be intevested to learn that Dr. Werner Braun, at Camp Detrick in Frederick

_ is a leading worker in this field.

Yours sincerely,

IRqI can be of any further assistance on
any specific point, please let ms know. Joshua Lederberg,

Associate Professor of Genetics
