Copy letter from Herbert Rix, to Messrs West, Newman & Company, 54 Hatton Garden, E.C. 'Please let me have, as early as possible, estimate for reproducing inclosed drawings as quarto plates for "Phil. Trans." ['Philosophical Transactions of the Royal Society'] by cheapest lithographic process. The figures might be reduced as small as the inclosed photographs if you think that they will come out as clearly that size. HR'. 27 July 1894
