[stamped, MAR 23 1966] [written in different handwriting, Mei Fradkin 1962-63] 3/16/66 Dear Josh, That was a very pleasant surprise to talk to you on the phone! I am sending you my notebook including the experiments in search for new linkage groups with high melting temperatures (e.g. 108, 109, 110, 111, 112, 113, 114 and 120) and some others -- perhaps you have some use too. Now I am somewhat more settled in this new academic surroundings, I am enjoying my teaching very much. In 1963 I remember a hand book [sic] on transformation was being put together at the Lab. Do you think I may have a copy of that? With best regards to you and Esther, Mei Fradkin P.S. Please let me have the notebook back when you are through.
