  <dc:title>Letter from Howard Walter Florey to H E Huxley, MRC Laboratory of Molecular Biology, Cambridge</dc:title>
  <dc:description>Discusses question of markers - might be possible to put enough heavy atoms into a protein to make it sufficiently electron opaque to show in the EM - thorotrast not very good as is rather toxic - comments on this - best to do as Huxley suggested and try to get out smallest particles from saccharated iron oxide - want something in range below 50A - comments on this.</dc:description>
