Following your suggestion, we will plan to go ahead with the course without any commitment from you,but with the hope that you will see your way clear to take part in it. In any event, we shall keep you posted on developments. I hope I shall be able to get up to Wisconsin during my stay in Chicago. However, I imagine I am going to be pretty busy, and rush to get back as soon as the series of lectures is over. I mey, therefore, not be able to make it. With best personal regards to you and Esther, I em Sincerely yours, Ge. W. Beadle GWBspr DW. Weyer be a a4 40. henis Yan hacens 2 Grease Coun sate tehon # be
