Copy letter from Herbert Rix, to Professor Michacel Foster Dr [Charles Scott] Sherrington wishes Rix to have his plates done by Morgan & Kidd, collotype process, but Rix suggested that an alternative estimate should be obtained from Cambridge, by photo-lithography. Morgan & Kidd's estimate is £80, and the Cambridge Company's is £81. Rix sends by the same post a specimen of Morgan & Kidd's work, which appears exceedingly good. Asks which estimate to accepted and whether, if Sherrington distinctly prefers one form before the other, his preference is to be followed. 28 March 1893
