Copy letter from Herbert Rix, to Dr James Samuel Risien Russell 'Dear Sir, Prof. [Professor] Victor Horsley has now written about the illustration question, and the Officers saw his note to-day. They defer the general question of photographic illustrations, and, meanwhile, have instructed me, so far as your paper is concerned, to concede the point. The brains will, therefore, be reproduced photographically by the Direct Photo-Engraving Co. I am, yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 27 July 1894
