  <dc:title>Letter from Howard Walter Florey to C H Andrewes, National Institute for Medical Research, Hampstead</dc:title>
  <dc:description>Will send penicillin  - Robinson is doing syntheses of simple tetronic acids - no reason to think they have antibacterial action - foundation for penicillin being a tetronic acid not clear - Raistrick has published paper on antibacterial substance he says may be better than penicillin - only penicillin so far has wide range between toxicity for cells and inhibitory powers for bacteria.</dc:description>
