Copy letter from Herbert Rix, to Dr John Syer Bristowe, Fellow of the Royal Society 'Dear Sir, Dr Foster wrote to you in October last year asking you to undertake an obituary notice of Mr F. Le Gros Clark [Frederick le Gros Clark], and to the best of my belief, you consented. We have never received the manuscript. Can you tell me when we may expect it? I am, yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 15 December 1893
