It must be for September rather than March,and I shall not presumably be ver to spend all the five months in the U.S.A. I hope, however, te sping + 3 months at your place. This might be enough fir some/Pegbard BRich we might plan in advance,and for which | would welcome your suggestions. As to my programme, 1 cannot fix it in detail since now, but it would be roughly «is follows : arriving to New York ig August, second half, spend a couple of weeks there and,if you will be at Ma- dison in the second or third week of Sevtmmber, join you there. I shall have to leave for italy shortly before or after Xmas,as 1 am supposed to be back here for Jan.15 . I would like to make a two weeks trip to Californiabmt have no idea where to fit this,as it depends on various circumstances, like Buzzati's presence at La Jolla,and the possibility of securing money for the journey (the Rockefeller pays only my travel to Madison). I imagine it should be easy to make ahorter trips from Madison to neighbouring places of scientific interest during the rest of my stay. , My fellowship will paymfor self and wife, $ 325 a month. This should be free of tazx,i imagine. I have no idea of the cost of life at Madison,and should be grateful if you could give me a rough impression of it. We would of course be without the children and some- thing like a dcuble-—bedroom with use of the bathroom would suit us. Re genetic analysis of drug resistance ; I wonder if we might dedicate a few evenings in Madison to writing xk the booklet you suggested ? A book of 10U-150 pages,expanding and completing the joint paper of Rome,especially if we agreed in advance on the contents, might be not too long to write down in detail when there,and my wife could help in the typing etc. 1 would care for the literature in advan- ce so as to have everything ready before I come. i would suggest to group the contents roughly as follows :; (i)drug action - types of drugsp their activities,mechanism of action,environment in which they act ; (ii)drug adaptation - genetics of the individual and of the population, experimentatl distinction, mutation to reshmbance,recombination , phy- siology of resistance,drugs gas indueers of genetic changes ; (iii)drug 3 association (synergism and antagonism, physiol.and genetical ; (iv)drug production — chemistry of drugs in relation to metabolites,and genetics of antibiotic producing strains.Of course, (ii) would be the central .y subject, out I think that an introductory (i) would be EES en BS (F) a uppae odd Con.
