To Ernst Haeckel 30 December  – 3 January 1
Down. | Bromley. | Kent. S.E.
My dear Sir
Your letters are always most kind.2 I shall be proud to receive your monograph on the Radiolariæ which I saw & much admired in London;3 but I know so little of the group that in truth I am not worthy of your present. I sent off a few days since to Jena a copy of a paper by me, which if you have time I think is worth your reading.4
My health continues very weak & I have no strength to spare, so I am sure you will excuse the brevity of this note.
With very sincere respect believe me my dear Sir | Yours truly obliged | Charles Darwin
P S. Jan 3.
By a mistake this letter was put in a wrong envelope & you will have have received another note addressed to a friend which I fear will have surprized you.5
Please to tear it up. As there has been so much delay owing to my unfortunate mistake, I have directed this to Jena instead of to Berlin6
Will be proud to receive EH’s Die Radiolarien .
Health continues very weak.
[P.S. 3 Jan] Has sent EH another letter by mistake.
