USEMOMETRICS AND INTELLIGENT LABORATORY SYSTEMS Dr. R.G. Brereton School of Chemistry Cantock's Close BRISTOL BS8 ITS Prof. Cc. Djerassi, United Kingdom Dept. of Chemistry, tel. (0272) 303030, ext. 4707 Stanford University, telex 444174 BUPHY Stanford, CA 94305, U. S.A. 26 Nov., 1987 Dear Prof. Djerassi: I wonder whether you could referee the enclosed paper by Gray entitled "DENDRAL AND METADENTRAL ...." submitted for publication as a tutorial article to CHEMOLAB. One referee was unable to review the article within a reasonable time so has returned it to me. Because this article is somewhat dong I think that, if it is not possible to review the article fairly rapidly, it would be alright if the review took 3 or 4 weeks. If you are unable to do this, can you pass it on to a Suitably qualified colleague in your laboratory, since this saves time and postage in the long run? I thank you, in advance, for your help, yours sincerely, 1 & G. Brereton
