WALTER REED ARMY INSTITUTE OF RESEARCH WALTER REED ARMY MEDICAL CENTER WASHINGTON 12, D. G. bes May 21, 1960 Dear Joshua and Esther: I sent off the Serratia cultures for Esther before I left for Utah, so I expect they have arrived by now. I guess Hertzenberg has filled you in on the (ugh) Symposium by now. I flew back to Chicago with Jim Crow which along with see- ing Hertzenberg was the best part of the whole trip. Lindegren asked me the same question over and over after the paper I presented in Phila. and although I answered him four times, he still didn't seem to hear me. I think he doesn't have all his marbles anymore. By & the way, the GSS approved the application(in case you hadn't heard), but, as you know it still faces the Council. The whole GSS session was horribly tedious and seems to be getting worse each time. Jim and I both wish you were still & with the group for many reasons. Best regards to all. As ever, J LA Division of Immunology
