Copy letter from Herbert Rix, to Mrs Marshall, Belle Vue House, Cheque Walk, S.W. 'Dear Madam, I much regret that our printers (whose business it is to dispatch our publications) should have been so careless as to overlook our notification of the death of our late eminent Fellow, Professor Marshall, which was duly sent to them on the 2nd January and that you should have had the trouble of returning the papers which they thoughtlessly posted. I am, Dear Madam, your obedient servant, Herbert Rix Asst Sec RS [Assistant Secretary, Royal Society]'. 7 May 1891
