Dear Professor Hilpinen:

	Thanks for your letter of December 23.  We will proceed as
you suggest.

	However, there is still one point that worries me.  I would
be entirely convinced by your letter if you were able to assure
me that there had been no problems recently or that they had been
successfully solved.  Professor Tandberg didn't answer the part of
my letter asking what success ICSU had had recently in assuring
attendance at international meetings in the Soviet Union.  The
problem is 20 years old, so there must be some record of success
or failure.
