Copy letter from Herbert Rix, to Professor Michael Foster, [Royal Society] 'Dear Sir, Herewith Marshall Ward on [Henry Enfield] Roscoe & [Joseph] Lunt's plates. It is a little awkward, as Roscoe got the proofs done on his own account. However, that is his own lookout. I have warned the autotype co [company] not to proceed with them till they hear further. Yours truly H Rix'. 25 July 1891
