Copy letter from Herbert Rix, to E Maunde Thompson, British Museum, W.C. 'Dear Sir, The prize for the trisection of the angle is, I believe, a popular superstition. We are continually having communications about it, but no such prize has ever been offered by this Society, nor, so far as we are aware, by any other scientific society. I am, yours faithfully, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 11 January 1894
