Mithun UNIVERSITY OF EDINBURGH PL DEPARTMENT OF ZOOLOGY, WEST MAINS ROAD, EDINBURGH, 9 iP) v Yv TELEPHONE 42080 2nd September Dear Josh, - I feel lukewarm: not anti, just lukewarm. He's certainly energetic, consistent, and thorough, to judge from his papers; and people here say that he is the best pupil Gorer has had. I dont know him personally at all. But again to judge from his papers, I dont feel he can have very wide interests: why work on mouse erythrocyte antigens, unless you have some wider purpose? And he seems to me to be rather laboring the question whether soluble antibodies kill some tumour homografts (or am I just bored with that one?). I should think that the main thing is to find out whether he is prepared to take an interest in the deeper sort of questions which you are asking. I've asked one or two people here about him (without saying anything about your idea,naturally), and they think much the same. But none of them knew him really well. But maybe you've already decided by now. And if asked for alternative sugestions, I feel stumped. By the way, I finally turned down the London job, and so will put out feelers about leaves of absence from here. I'm hoping to have the chick erythrocytes tteared up and ready for publication by the end of the year. I think there's a pretty sharp limit to the extent, pne can take such a complex antigenic system; I'm starting on S sulphanilic acid-azo-protein, but so far nothing has worked well. Did you see Boyse's result that spleen cells from an immunised mouse made much more antibody after transfer into an Fi than alder iso-transfer? This might be a difficulty for you, but of course it might be many other things.
