  <dc:title>Letter from Howard Walter Florey to N G Heatley, New York</dc:title>
  <dc:description>Thanks for details of new culture medium - gives details of brews - received penicillin from ICI but highly pyrogenic - gives details of discussions with ICI - could Merck send capsules coated with the cellulose acetate mixture - is using Rake's strain - seems to grow and spore better but yields not very different from strain sent to Heatley.</dc:description>
