  <dc:title>Letter from Howard Walter Florey to H L Riley, Sparken Hill, Worksop</dc:title>
  <dc:description>Thanks for samples of carbon - two of the tubes were broken in transit - have looked at the Thermak Soft carbon black, which seems alright for particle size - cannot inject material containing tannic acid or ammonia - comments on this and on Hydrokollag 300, which was suspended in cherry gum - carbon suspensions must not clump in presence of blood serum - thanks Riley for his help.</dc:description>
