Down Farnborough Kent
May 5th.
My dear Sir
I write to acknowledge the safe receipt of your two specimens & to thank you for your constant & kind regard to my pursuits.— The valves are new to your collection; but they are unfortunately valves on which specific names cannot possibly be founded.—
Yours sincerely | C. Darwin
