  <dc:title>Letter from Howard Walter Florey to R J V Pulvertaft</dc:title>
  <dc:description>Says that Poole is sending some penicillin - says that the commercial stuff is now much better and it is common to have material up to 500 units (per mg) - thinks that Pulvertaft's experiments would be more worth while with purer material - hopes he will be successful in Jerusalem - would like reprints relating to Levin's apparatus.</dc:description>
