Your report on penicillin, showing that we are only to get about one-tenth of the expected output this year, is very disappointing. It is discouraging to find that, although this is a British discovery, the Americans are already so far ahead of us, not only in output but in technique. I hope you are satisfied that we have the right people in charge and that labour and material difficulties are being tackled early enough and energetically enough.
Pray let me have a realistic estimate of 1945 production.
