Copy letter from Herbert Rix, to Dr John Berry Haycraft, the Physiological Laboratory, University of Edinburgh Dr [Michael] Foster wishes Rix to ascertain Haycraft's wishes about the photographic plate illustrating Haycraft's paper. Dr Klein suggested the Autotype Company who do such work in first rate style, and they will send the work there unless Haycraft has some other views on the matter. Rix asks for an early decision and if the plate is to be done in London he ask that the negatives be forwarded. 5 January 1891
