Dear Josh, _

Since I came back to Japan, I have had to bound up
in the arrangement of the Annual Meeting of the Genetics
Society of Japan. The day before yesterday the meeting =
had finished and now I can come back again to my routine.
life in my laboratory after two months lapse. -

_ Today I will start the test of lysozyme and sodiun
lauryl sulfate sensitivity of two phase cultures.
Is there any progress in the repeating experiment oh
_phase-l and phase-2 DNA density gradient? I understand —
you are going to test the reproducibility of the phase-]
and phase-2 difference with the same DNA sample as I ..
used; and if the difference is really between two samples,
to investigate whether the difference is in basé compositian |
or not. oS OT

I recalled I have foregotten one business before Tleft
Stanford: I received 5,000 yen from you just before you ~~
left from Haneda, expecting to return by U. S. dollar when
I visited Stanford. Carelessly I brought back them and”
exchanged all U. S. dollar I.brought back Japan to. Japanese
yen. It is not impossible but cumbersome to reexchange
and send back to you. So, If you do not mind, I would like
to keep them as your Japanese fund ( I guess it igs convenient
for you in some occasions). ‘Please: let me know any time —
in cases you want to get some Japanese goods by the fund,

Best wishes to Esther and the people in your lab.

Sincerely yours

Tetsuo Iino
