Copy letter from Herbert Rix, to Messrs West, Newman & Company, 54 Hatton Garden Herewith are three maps to illustrate a 'Philosophical Transactions [of the Royal Society]' paper by Messrs [C Barrington] Brown and [John Wesley] Judd, for estimate. The coloured spots showing the position of the mines are to be reproduced on the geological map, thus reducing the illustrations to two maps instead of three. [May 1895]
