Copy letter from Herbert Rix, to Professor Worthington, 6 Osborne Villas, Devonport 'Dear Sir, Of course you can have access to your unpublished illustrations, but I am sorry to say that we cannot post them to you. They are bound up with other manuscripts, and no manuscript is allowed to leave the house without the permission of the Council. Perhaps you will be able to call here when you come to town to give your lecture. I am, yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 16 February 1894
