  <dc:title>Letter from Howard Walter Florey to E Gurr, Michrome Laboratories, Upper Richmond Road West, London</dc:title>
  <dc:description>Thanks for information about carbochrome ink - application of this to endothelium results in outlining of cells with lines similar to those produced by silver staining - discusses this and possibility that phenomenon might be due to ionic detergent in the ink - asks for a sample of the carbon without detergent - would be interesting to see if cetyl trimethyl ammonium bromide, a cationic  detergent, were effective.</dc:description>
