  <dc:title>Letter from Howard Walter Florey to R D Coghill, United States Department of Agriculture, Peoria</dc:title>
  <dc:description>Excited that Coghill can brew material of 200-220 units per cc - considerable delay in getting Coghill's reports - could they be sent direct - has material of 1000 unites per mgm, very potent but not pure - has about half the molecule crystalline.</dc:description>
