  <dc:description>Gives details of a sample of the barium salt of penicillin which he is sending - discusses assays of Merck's purest material - possible that standards at Oxford and at Rahway do not agree - has given account of Merck's penicillin work to the TRC - will be a good thing when true pooling of information is possible.</dc:description>
