Copy letter from an unknown correspondent, to the Cambridge Instrument Company The correspondent has the Messrs estimate for the two plates to illustrate Dr [Charles Scott] Sherrington's paper. He asks the Messrs to ascertain if Dr Sherrington will allow the disarrangement of the figures and to ask whether Dr [Michael] Foster approves of the estimate. They can then proceed with the plates and the correspondent would be glad to know approximately when they will be finished. 2 April 1890
