Lindegren Southern 111 U data from yeast genetics . The mathematical formalization of oreesing~over is an impertent research area that has ocoupled the attention of a variety of workers (e.g., the very elaborate proposale of Oven and Sir Renald Fisher). A hasty reading of Seult's analysis (to ubich T had access independeAitly ef the SF, and whieh was not furnished with the application) leads me to think thet he hes made en interesting advence in the applicetion of a preup—~tieeretieal approach (a notion on vhieh I wnsuscersfully sought te elicit sane mathematical interest in 1947) and he appears’ to have been able to simplify end generalize seme derivations in tetrad theory, This work should definitely be encouraged, and Scinlt seems rather ebright lad, but I doubt that this is the right track. No theoretical development that is goings to require expensive machine-——~programing is going to be partieulably useful, and I suspect the theary isself has not yet been The data that the Lindegrens hace sccwslated be entirely feasible on a nore modest basise after they have hed a preliainary survey ve could moaningfully enquire whether they warrant the type ef analyais indicated here. 'g reputation and atanding have been reviewed in pfevicus evhhuations, end I meed not repeat my previous remeris, It is characteristic that he should ask for $800 travel for a stationary project. I think enough ef Selult to vant te keep him in business, It is a question I cennet snewer whether he would not be far better off in mere rigorous surroundings; one recamendatéon I would be prepared to consider would be a grant sufficient to subsidize his om salary, i.e., about 4500 altogether. ; DW From 5 Clow) to 1 (high) Signature
