6/25/51 Dear Josh, Enjoyed the chapter very much. It will be a useful thing indeed in tracking new students. Jane glanced through it, and I must agree with her--it is damn well written. I have only two minor comments. 1) Page 97. (footnote) Though we did find no accumulation of mutants in resting cultures, we did not report this observation--as stated in foot note. 2) Page 99--Sixth line from bottom--definite article before "zero term . . . "? By the way are any arrangements being made to reproduce your C.S.H. ms? We would like a copy very much. I caught my first cold the Saturday after the symposium and am just recovering.
