The lack of interest on the part of our children for America is, I think, only a consequence of the fact that they are used to consider the summer by the seaside as the best part of the year and they don't like to leave the certain for the uncertain. I agree it may be a consequence of the conservative education they get in Europe. ke. opportunity such as the one suggested in the paper ott. bent by Esther seems interesting. I do not mind spending up to 250 dollars for lodgings, especially if it means something really attractive, perhaps nearer to the lab and with an extra room that can be used as a study and left in complete disorder without hurting Alba's feelings too much, I am getting worried about the impossibility of smokin in your department.

We have now discussed with bedte and Scossiroli and there should be no major problems for including a programme of the kind.

We may perhaps discuss in more detail the programme in the summer. The programe, will, however, suffer from the block which presently hinders all fluorination activities, namely the fact that we haven't yet been able to get a copy of the Handbook of Fluorination. We are looking forward to visiting Stanford and we ask for some tips on the expected temperature and weather. Bree nF ON All the best, Yours, hu Cw Encl.
