2/10/69 Dear Dr O'Brien -- Thank you for your painstaking and thoughtful reply to my questions. I will of course honor your confidences. However, I would encourage you to bring any abuses of trust in grant selection to the attention of Dr. Maiston [sic] as Director of the NIH Your critical survey of clinical test methodology in the evaluation of indomethacin was most illuminating. Quite apart from basis of financial interest, I suspect that misguided optimism may be the worst culprit! I will plan to write something further about tighter controls on licenses to prescribe new drugs. Thank you for your suggestions. Sincerely, Joshua Lederberg
