To John Davy 25 March 
Down Farnborough Kent
My dear Sir
I arrived home late last night, (bringing with me the Angler & his Friend)1 & found your Paper2 here; I write this merely in case that you might be surprised that I had not earlier acknowledged its safe arrival.—
I assure you I feel much pleased & flattered by the form you have done me the honour of putting the communication under.3
In two or three days I will forward it to the Royal Socy. & do myself the pleasure of writing to you again.—
In Haste pray believe me | Yours truly obliged | Charles Darwin
Will forward JD’s paper to the Royal Society ["On the ova of salmon", Philos. Trans. R. Soc. Lond. 146 (1856): 21–9].
