|Copy letter from Herbert Rix, to Dr [John Berry] Haycraft, Physiological Laboratory, University, Edinburgh
|15 May 1891
|'Dear Dr Haycraft,
Dr Michael Foster has instructed me to get clichés prepared of the illustrations to your striped muscle paper, in anticipation of the leave of Council. I must explain that the original blocks never under any circumstances leave the house, but that the clichés can be sent to you at your own expense & that the expense of clichés is very small.
Asst. Sec. R.S. [Assistant Secretary, Royal Society]'.
