January 16 Dear Joshua I am sorry I didn't manage to send you in time my manuscripts for the APPS meeting. You know how these things are: you are never through until the last day. I hope they will not publish a volume on the Symposium, but in case they did I would like to know what you think about my paper. I also proposed to Wanrich, who organized the Symposium [END PAGE ONE] [BEGIN PAGE TWO] to split viruses from bacteria, and to ask some body else to do these last ones. If you happen to have a little time free, you might take a look at the paper and tell me very frankly [?] what you think about it. I am starting now for California where I will be with Delbruck until the end of February. Very sincerely yours Niccolo
