Dear Josh:

Henry Vogel and I are writing a new chapter on "Morphology,
Physiology, and Genetics" for the 3rd edition of Dubos! "Bacterial and
Mycotic Infections of Man." We would like to use your Figures 1 and 2
(conjugal pairing) from J. of Bact. 71: 497-498, 1956, and would
appreciate both your permission to do so and the appropriate glossy prints.

Following your concurrence permission also will be requested from the
publisher.

With very best regards to Esther and you,

Sincerely,

Ode)
