  <dc:title>Copy letter from A H White, to Lord Rayleigh [John William Strutt], Secretary, Royal Society</dc:title>
  <dc:description>Regarding [Walter Noel] Hartley's 'Philosophical Transactions [of the Royal Society]' paper, the author has sent his two small negatives and White has seen the engravers, the Direct Photo Engraving Company. Suggests how these and Professor [Joseph Norman] Lockyer's plates should be executed resulting in a financial saving. The Company said they cannot recommend zinc blocks for such fine works and it is the Society's experience that it is an unreliable method, so that it seems a pity the things were not both arranged for collotype from the start. </dc:description>
