December 7, 1953 Dr. Shozo Inoki 109 Wylie Hall Indiana University Bloomington, Indiana Dear Dr. Inoki: Thank you for your letter of November 28. I am happy to learn of your safe arrival at Dr. Sonneborn's laboratory. I will, of course, be very happy to re- ceive your visit here at any time subject to your own convenience. As I have indicated to Dr. Sonneborn, however, I expect. to be visiting Bloomington myself sometime in the spring, so that a favorable opportunity for our meeting is thus doubly assured. I note with interest that you are now undertaking a study with the trypan- osome which possesses a kinetosome. I hope that in addition to your studies with antiserum you will also have the time and inclination to review the earlier observations on the effects of various dyes on the supposedly induced disappear ance of the kinetosome. May I inqiire whether you are well acquainted with one of your countrymen, a Mr. Tetsuo Tino, now at the National Institute of Genetics in Japan. If so, I would be indebted to you for whatever appraisal you would care to make with respect to his application for a fellowship in this department. Yours sincerely, Joshua Lederberg, Associate Professor of Genetics /mg
