Dear Professor Lederberg :

I am preparing for the trip to U.S.A. and I shall arrive in Palo Alto
on the 30th May and as I told you, I shall be glad to see you on the 31st
and give a seminar on one of the following topics ;:

1) Chemical Nature and Biosynthesis of Streptolysin S!' .
2) Ribonucleases in Takadiastase : Chemical Nature, Properties

and Applicationd,

The Ministry of Education of Japan is now planning to establish
an Institute on Space Science, in which a section on space biology
is considered. I, as one of the consulting staffs for the Institute,
should like to see several laboratories besides yours, in which space

biology is studied. So I should like to ask you if you could tell to

Dr. M. Ohashi and hés wife, both my former students, will take
care of me during my stay in Palo Alto.
