Thanks for your letter. The Retrovirus Study Group keeps a low profile and is only hurled into action if the Chairman aggressively
seeks problems (I do not) or if someone brings a problem to its attention. It doesn't seem to me that there is a significant
problem in retroviral taxonomy at the moment, though I would hope you will let me know if you think there is an issue involving
the new human isolates that we ought to consider.
I appreciate your asking me to visit on the way to Cold Spring Harbor. That will not be a leisurely time of the year for
me, so I must decline. However, I may be at NIH on May 3 or 4 (for some discussions of hepatitis B virus) and might well
have some time on the afternoon of the 4th. If that is a good time for you, let me know and we can get together informally
(assuming I actually go). I would, however, prefer not to give a seminar on that visit; a group discussion would be fine.
