I want to take this opportunity to express my personal appreciation for your dedicated participation in the work of this Committee, which I consider to be one of the most important activities of the Academy. I recognize that your contribution has been a major factor in the success of the Committee's meetings with the Soviet Academy on issues of international security and arms control. I am particularly grateful for your successful initiation of a dialogue on BW with the Soviet Academy. There is one procedural matter to which I must call your attention. As required in the appointment of Committee members, I am enclosing a copy of the statement, "On Potential Sources of Bias." If there have been any changes in your situation since your original appointment to the Committee, please return the form attached to my office with your letter of acceptance of this appointment. Thank you again for your contribution to this unique Academy activity. Yours Sincerely, Conk President.
