Copy letter from Herbert Rix, to Professor Arthur Rucker, Fellow of the Royal Society 'Dear Sir, With reference to Captain [Ettrick William] Creak's paper, I find that your recommendation that the geological map in 10 colours should be simplified has not been carried out, and certain other points in the latter half of your report have been overlooked. Before I proceed farther with the paper, I should like to know that it is with your knowledge that these points have been omitted in revision. I am, yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 18 December 1895
