  <dc:title>Copy letter from Herbert Rix, to Professor James Dewar</dc:title>
  <dc:description>'I have resuspended at your request the certificate of Mr Ludwig Mond. Nothing can be added to the certificate now that it is signed. Additions can only be made by taking out a new certificate &amp; getting new signatures to it. 
Yours truly
