  <dc:title>Letter from Alfonso Sella, Istituto Fisico, Rome, to Charles Vernon Boys</dc:title>
  <dc:description>In the course of experiments on diamagnetism, he has difficulty in finding a perfectly elastic thread. Having read Boys's paper on the properties of quartz fibres, he asks if Boys could send some. The fibre would have to bear 6 grammes and should be at least 40 centimetes in length. </dc:description>
