Dan Callahan [stamped, JUL 28 1985] Dear Dan Another dinner [?] -- Thank you, but I really can't. I know you mean well. Yours, Joshua. I'm glad you have Jack Whitehead as a backer. I wish I could say the same on behalf of R.U. -- after untold hours of effort for him in the (good) work(s) of establishing the Whitehead Institute. Whitehead D.C. 7/29/85 arr
