Dear Dr. Lederberg:

Please excuse me to write this letter
after a long silence, because I am very glad
to inform you that I had a position in Sonneborn's
laboratory, Indiana University, Bloomington,
Indiana. As you suggested to me, J oan say
that he was kindly interested in my work on
the antigenic variation in Trypanosoma gambiense.

Now i am very happy to be able to have
a good’ oppotunity for my further studies on
the cytoplasmic inheritance of protozoa. Before
anything, therefore, I thould be very grateful»
to your kind suggestion.

according to my plan, I shall start here
at the beginning of September and arrive to
Bloomington by lst of October. When I shail
have arrived there, I shall be very glad to
see you and to discuss about cytoplasmic inheri-
tance. If you would kindly manage to make

‘an opportunity for seging se, I should be via nwrch
thankful to you. we

With best wishes, —

Very truly yours,

shozo an M.D.
