We will be very happy to offer you the facilities of our laboratory for a month in Septeyber. Our own plana, at present, are to attend the International Micro- biology Congress at Stockholm, returning to tiemdix Canada in tine to attend the Genetics Congress at Montreal, and fron there home, For this reason, it would be perhaps most convenient if you could postpone your arrival at Madison until a week or ten days after the Congress, This will perhaps afford you time to visit sane other institutions en route, and will let me catch up on ny paper~work before your arrival. If this is agreeable to you, we can discuss further details at Montreal, and perhaps Stockholm as well. I am very much interested in your remark about the inheritance Ss of cold-induced reshstance. Do you think it applies when the = g (F*) parent is the resistant one? Perhaps this is a point we x Soul plan to clarify during your visit. / ay % fe i os Yours pltearaly f ad & ae pos J ogtiua lederberg Chairman, Department off Medical Genetics P.S.
