Dear Joshua, this is to keep you up to date with Interist. No final decision has been taken yet. We have received a formal dismissal of the contract within the legal deadline and thus our fi- nancement should end with July 1964. We have how- ever received,not formal offers, but hints that offers for renewal might be forthcoming both from Lepetit and, less clearly, from Schering. We will hear about Schering's proposals, if any, in Decen- ber or January, when luca will go there, while Le- petit will be in a position to make a formal offer only in Febraary or March. They are now undergoing chayges and have requested us not to make a sepa- rate agreement with Schering before consulting them. In the present circumstances, we can only guarantee,‘in:accord with our agreemant, to pay your fees for the period January-June 1964, as our present contract with Interist expires at the latter date. But we would be very grateful if you would not take other engagements for consulting ./- on antibacterial substances until the end of March 1964, or at least until one of us will see you. We have been testing some fluoro . DAP derivatives. The experiments are not complete, but there is nothing exciting sofar. We will re- sume fluoropoiesis soon. Giovanni is now in the chair at Parma. All the best, bn Oo L.L. Cavalli-Sforza GE. Magni
