 My Dear Dr. Torrey


 I send you a slip containing
 the reference to plates
 for Sitgreave's report. I find you do not
 agree as to names in the [message?] sent
 me. Please make in the proof the
 corrections desired and return immediately. 
 I will try to delay the printing
 for a few days - but the proof
 should come back by return
 of mail.


 Yours truly,
 S.F. Baird
