  <dc:title>Letter from George Gabriel Stokes, Lensfield Cottage, Cambridge, to Charles Vernon Boys </dc:title>
  <dc:description>He finished his last letter in a hurry and forgot to say that D referred to diameter. He has not yet attempted to fully calculate bands for the transmitted light. For a complete theory, diffraction as well as refraction would have to be taken into account. In calculating the polarisation of the diffracted light, he relied upon a result he produced long ago in a paper for the Transactions of the Cambridge Philosophical Society. A crucial experiment in that paper could be done more simply with a silvered quartz fibre, but he does not have time to perform it.</dc:description>
