Copy letter from Herbert Rix, to Professor David Ferrier, Fellow of the Royal Society 'Dear Dr Ferrier, Dr Foster wishes me to write and say that the referees are of opinion that "a smaller number -- perhaps half -- of the figures sent in might be selected for publication. Many of the photographs, they think, "are not strikingly demonstrative" and might be eliminated. I am sending back the paper that this may be done. I am, yours faithfully, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 29 May 1894
