Copy letter from Herbert Rix, to the Cambridge Scientific Instrument Company Admits to a possible error in the matter of the plates for Victor Alexander Haden Horsley and Edward Albert Schafer's paper, with Rix having recorded in his book that the plates had been sent, while he in fact has three still in his possession. Rix notes that he will send them by this post, and asks to know how matters now stand. The text has been printed so the numbering of the plates cannot change. 24 January 1888
