I am attach- ing an organization chart which will show you that many of our people do not have very much background in bacteriaf genetics. It would be nice if you could make it on Thursday, mt if not, we can arrange a special seminar for Friday morning, I am looking forward to seeing you. Sincerely yours, #lexander Hollaender,.
